If you're a DIYer, you'll love this product
By Ventois
If you're unfamiliar with this type of punch and don't understand exactly what's meant by descriptions like "dual-head," just enlarge the Amazon photo showing the handle with two cutting heads attached and you'll get an idea of what makes this punch set unique. This exact same 27 piece kit (25 cutting heads + handle and mandrel) is sold in the U.S. rebranded under other names besides Mayhew -- such as AllPax (100K27) and Allstate (KP-100K27-AG) -- and at wildly differing prices peaking at over seven hundred dollars. They're all made by Boehm in France, which sells them in Europe under their own name, this particular kit being Boehm item number JLB350US. The "US" designation at the end is a nod to the fact these punches are made in imperial inches per U.S. preferences. Boehm also makes sets in metric sizes which are carried by some U.S. retailers under various distributor's names. The dual, interchangeable cutting head design is supposedly patented, although I can find no mention of a patent listed anywhere on the items. I only mention all this for those who may be comparing identical-looking kits under different manufacture's names online and wondering if there's a difference between them. There's not. Boehm apparently has a monopoly on the dual head design; patent number or no.For the record, Boehm manufactures one U.S. kit that's more complete than this, containing 34 cutting heads going up to 2 3/8" (Boehm item no. JLB260MTRUS -- or Mayhew 66016, which differs from the Boehm version only in that it doesn't include a separate centering pin). I couldn't find the larger kit at a reasonable enough price to justify its purchase, but no matter: the 25 cutting heads included with this kit should be sufficient for the majority of the cutting needs most of us will ever encounter. Some retailers selling these kits also sell the additional 9 punches separately if you want the complete set of imperial sizes, but they're pricey: around forty dollars each.Okay, down to business. First off, although the cutting heads appear to have a shiny chrome-like finish in the picture used here and elsewhere (at least at the time of this writing), the finish is in fact black oxide, and oiled. I have no idea what grade of steel the heads are made of, let alone where they'd fall on the Rockwell hardness scale. The best I could find was the description "high-resistant steel" on Boehm's website, so we can reasonably assume it's some sort of alloy. They appear to be quite well made; I could find no imperfections with any of them. All are sufficiently sharp and stout enough to withstand some punishment.The chrome-plated handle and mandrel are beyond stout -- they're bomb-proof! Weighing in together at almost 2 lbs, they're built for abuse. The mandrel which the cutting heads attach to -- that's the cone-shaped, ridged item you see in the picture -- screws onto the end of the well-knurled handle. Boehm makes some punch kits containing fewer and smaller cutting heads, and those kits come with the mandrel pre-attached to the handle. To do that with a mandrel capable of handling 2" punches would have resulted in a storage case incapable of fully closing and making stabilizing contact with the punches, so the mandrel is separate and lays flat in the container for these larger kits.This kit comes with no instructions because none are required. Once you screw the mandrel to the handle, attaching the cutting heads is easy. The cylindrical mandrel has four different levels of circumference, each with a shallow groove in its side allowing the cutting heads to attach with just a quick turn. Because the base on most of the cutting heads falls within four different sizes, they're able to attach to a mandrel that accommodates only four different sizes. The exceptions are the five smallest punches, which screw into a threaded opening in the mandrel's center. Because these five smallest punches -- which are 1/8" - 3/8" -- can only occupy the same threaded center, you cannot cut washers of a size that requires more than one of them. All of the threaded items worked smoothly together - no tight spots. The handle screwed into the mandrel with ease, as did the smaller punches into the mandrel's center.Once you've selected and attached the cutting head or heads it's just a matter of giving the butt of the handle a good whack with a hammer to cut your gaskets, washers or solid disks. Although this can be done with any hammer, I highly recommend using either a non-metal, shot-filled dead blow or regular soft face hammer of at least 24-ounces for precise impact and to prevent peeling chrome from the handle. For thicker materials -- especially rubber -- a hammer heavier than 24-ounce will be required. A vinyl cutting mat is also recommended. If you use wood to absorb the blow its fibrous nature will be rougher, over time, on the cutting heads sharpness, as well as likely contributing to some unwanted flaring with your cuttings due to most wood's softness. Most rubber mats could introduce similar flaring problems because of softness. So for the cleanest cuts and maximum cutting head longevity a vinyl cutting mat that's at least 3-mm thick (beware of ultra-thin Olfa mats!) and around 8-1/2" x 12" is all you'll need to handle all your hollow punching needs.One gripe about this kit (besides the steep price): While the polypropylene molded storage case is nice enough, for some puzzling reason the red interior compartment that holds all the pieces has been molded out of ultra-cheap polystyrene; one of the flimsiest plastics available. Even the clear plastic used for the throwaway "clamshell" packaging on new goods -- usually PVC, but more recently PET -- is of much better quality than polystyrene. Whether this was Boehm's call or the re-branders I can't say, but whoever was responsible made a poor choice - poor enough that I've docked the kit one star in my rating. Polystyrene is fine for cheap children's Halloween masks, but a tool kit of this cost and quality deserves a more durable interior.Like most specialty tools of this type it's overpriced. Although I had to swallow hard before laying down the cash for it, I can already see it's a purchase that pays for itself over time; its uses for fabricating and repairing are unlimited. Its ability to cut interior and exterior portions of washers and gaskets simultaneously have made it invaluable; most recently for some washers cut from teflon that have allowed an automatic dishwasher's spray arms to once again spin freely. I'm using it for numerous other jobs I've been putting off because of the time, frustration and wasted material that frequently result from attempts to create perfect gaskets and washers with a standard punch equipped with a wobbly, spring-loaded centering pin. If you're a DIYer you can't go wrong with this -- it'll outlast you. Cheap polystyrene interior excepted, of course.Postscript: After writing this review Grip-On Tools released its model 61080 hollow punch kit, which is considerably less expensive than any other dual-head 27 piece kit I've seen. Put "grip 61080" in the search field here at Amazon or Google to find it. Having never seen the Grip kit I can't vouch for its quality, but given the price difference it may be worth taking a chance on if this is an item you'll only put to occasional use.

Outstanding tool...
By Victor H. Agresti
Mayhew 66002 1/8-Inch to 2-Inch Imperial SAE Hollow Punch SetI needed a professional dual hole punch to make washer shape cutouts in soft materials. Based on my research, the only high quality product of this type on the market is made by Boehm (in France). This 66002 set is a Boehm punch set rebranded by the Mayhew Steel Company; see mayhew dot com for more information. (Note: the "Grip 61080 punch set" is an attempted clone of this set, for 1/6 the cost - but is Chinese import "quality". Just read the Amazon reviews.)This punch set can cut circle shapes if using one punch or dual cuts when using two punches simultaneously; i.e., a circle with a hole in the middle, a washer.First, screw the mandril onto the handle. Then, to use as a single punch, simply mount one punch onto the mandril. To use as a dual punch, mount an inner and outer punch on the 4-step mandril (part number 50540). Single punches of 3/8" or less can be screwed into the mandril center or directly into the handle, while larger punches screw-lock (1/8 turn clockwise twist) onto a "step" of the mandril that matches the punch's base size.Mayhew punches come in SAE (inches) and metric sizes. There are 34 different SAE sizes - 1/8" to 2 3/8". That's Society of Automotive Engineers. Although available individually, it's more economical, per punch, to buy one of these SAE sets (all sets include a case):66000 - 16 pieces: 15 punches (1/8" - 1 3/16") + handle/2-step mandril w/centering point66002 - 27 pieces: 25 punches (1/8" - 2") + handle, 4-step mandril66008 - 11 pieces: 10 punches (1/8" - 3/4") + handle/1-step mandril66012 - 10 pieces: 09 punches (1/8" - 11/32")+ handle (no mandril)66014 - 18 pieces: 15 punches (1/8" - 1 3/16") + handle/2-step mandril and compass66016 - 36 pieces: 34 punches (1/8" - 2 3/8") + handle, 5-step mandril66080 - 28 pieces: 26 punches (1/8" - 2") + 2 piece handle set w/centering point, 4-step mandrilSet 66012 is single punch only - no dual punch capability.Sets 66000, 66012, 66014: mandril is part of the handle.Sets 66002, 66016, 66080: separate handle and mandril.Set 66016 includes all 34 sizes, but costs twice as much as the 66002 set.Set 66002 lacks the 5 largest punches (2 1/8", 2 3/16", 2 1/4", 2 5/16", 2 3/8") and four of the smaller punches (5/32", 7/32", 9/32", 11/32"). Individual punches retail in the $12 range for the smaller punches and over $60 each for the largest sizes - although discounts can be found if you do your research. As of this writing, Amazon doesn't sell those small sizes. To expand the 66002 set to include the five largest punch sizes would cost over $300, since these are the most expensive punches, and you would also need to buy the largest (5-step) mandril (part number 50539). If you ever plan to do that, you should save money now and just get the 66016 set, which includes all 34 Mayhew SAE size punches.The inside and outside of a washer must be from a different group of punches. I.e., the outer size must be in the group of punches that fits on a larger-diameter mandril step than the smaller punch. See the 3rd Customer Image for a graphic showing how this works. This set can cut 200 unique washer sizes (different inside and outside diameters). By also purchasing those 4 small punches cited above, 450 different washer sizes can be made.Quality of the handle, 4-step mandril, and punches - is first rate, and the cutting edges are all sharp. The mandril and handle are super heavy duty, and definitely up to the task. The polished part of the punches shown on some product photos is actually blued steel on my set; similar to a rifle barrel. The kit box should be of thicker plastic, but is OK as is. The box liner is another matter. Although well designed with a molded recess for every part of the set, it's made from cheap, very thin, polystyrene - mine arrived with part of it already cracked. Clearly, for the price of these sets, Mayhew should do better.The inside of each punch slightly tapers to a larger diameter from the cutting end, to simplify extraction of the circle cutout. Although machining of this set is seriously impressive, it's not perfect. That is, two punches on the mandril work best if both end at precisely the same spot; i.e., they touch the cutting board together. While that's true for many combinations (I didn't try them all), some are off by the tiniest amount (1/100" +/-). E.g., the 3/16" punch on my set is slightly shorter (when mounted on the mandril) than the outer 5/8" punch on the mandril. I suppose this is nitpicking since, with the proper cutting board, the tool works fine. Mayhew's online catalog doesn't say what kind of steel is used, but it appears to be very high quality and the punches arrive sharp and have stayed sharp through many cuttings. You might have to replace dulled or damaged punch rather than sharpening, IF sharpening would shorten the punch too much.It's crucially important to use a good cutting surface with any hollow punch. The C.S. Osborne Cutting Pad 10" X 10" is designed specifically for this purpose, although plastic kitchen cutting boards are much cheaper, and work very well. An end-grain hardwood cutting board might be worth a try, but a simple wood board would typically be too soft. Even side-grained maple is insufficiently hard, in that the cutter digs into the wood too far. If the cutting board is too soft (side grain oak, maple, birch, etc.) or too hard, the cutter blades could be damaged and performance compromised.I've used the 66002 to cut rubber, leather, foam, and thick felt, and it works very well. It will cut through most any soft material (lead, some types of fiberboard, soft plastics, foam, rubber, etc.). If it won't cut cleanly, experiment. For example, it's problematic making a clean cut through felt with just a cutting board - but, by laying a 1/8" thick rubber sheet on top of the cutting board, with the felt on that, it's a cinch - the two punches slice through the felt and the rubber. I use a 32 ounce steel hammer - it scuffs & slightly dents the end of the handle that gets whacked, but, so what - that's what it's for.I bought my 66002 set from MROcenter dot com, an Amazon external website vendor, for $285, w/free shipping. I bought those four small punches cited above for around $42 (includes shipping), from MyToolsForYou, an internet retailer.The big negative with this set is price. The manufacturer (Boehm) sells it to Mayhew, who sells it to a retailer, who sells it to a customer. They all make a profit off of YOU, which jacks up to price. Of course the fundamental reason for the high price is the tool's very high quality.This product could be "better", as identified above, but it's already outstanding...
