Holistic Drill Bit Gauge - 3 Drill Bit Gauges in One

I wanted to buy another Hanson Drill Gauge (enameled steel, Made in USA), but can't find that brand, so I bought this instead. The Bonewright gauge is well made of a sturdy plastic-like material, & it has measurements in fractions of inches & metric (millimeters). What I like best about it is the instructions (on 4 typed legal sized pages) which are extremely well-written, clear, & informative. Most pros will probably not need this info, but I found the section on bolt & screw measurements (which this gauge does as well, up to 6 inches, in one-eighth increments) to be informative. Well worth the money.

I picked up the Holistic Drill Bit Gauge to identify drill bits with faded or missing size markings. This gauge is made from a 1.6 mm (about 1/16 inch) thick PCB board, similar to what’s used for computer motherboards, which makes it much sturdier than the usual thin plastic gauges. This tool has three measurement scales in one – it covers metric sizes from 1.0 mm to 13.0 mm (in 0.5 mm steps), imperial sizes from 1/16 inch up to 1/2 inch (in 1/64 inch steps), and numbered drill sizes from #1 to #60. I checked several of my bits, and every hole was spot on with the markings. It’s easy to check both mm and inch sizes, which saves a lot of time if you work with both kinds of bits. The overall size is about 15 cm by 5 cm (6 inches by 2 inches), so it’s compact enough to toss in a toolbox or even keep in a pocket. For the price, you get an accurate, easy-to-read, and tough tool that’s way more durable than any cheap plastic gauge. PROS: 1.6 mm (1/16 inch) thick PCB board construction for durability Measures metric (1.0 mm to 13.0 mm), imperial (1/16 in to 1/2 in), and numbered drill bits (#1 to #60) Holes are precisely cut and labeled clearly Compact size – 15 cm x 5 cm (6 in x 2 in) Excellent value for the price CONS: None I’ve found so far at this price point SUMMARY This is a sturdy and accurate drill bit gauge that’s great for anyone needing to check both metric and imperial sizes. The build quality is solid for the price, and the measurements are reliable. Definitely recommend this to anyone with a collection of bits where the sizes aren’t marked or have worn off.

Good sturdy guide. Comes with detailed instructions and info on sizing correctly

I haven’t actually used this yet. Awaiting delivery of a new bulk drill bit indexing chest. However: I am a senior citizen tech guy and I am very pleased with what I see. I imagine that this manufacturer make quality mil spec pc boards for a primary business. This gauge is a great diversification. Sequential sizing is perfect for sorting a vast quantity of drill bits into my new storage system. Easy to read. Nice look / feel. Seems durable enough for its purposes. I’ll try to remember to update after the big (maybe 800 pieces) exercise upcoming. The instruction and tip sheet is an excellent essay. Informative, fun reading You left a minor typo for us to find; and I did ! Unfortunately, I’ve misplaced it. When I find it again I’ll be specific if you need. I might have been even happier if it stretched to 1/2”.

I have a bin of bits that are jumbled. I'd like to put them back in their marked slots, but the sizes have rubbed off the bits. First day I got it, I was on the hunt for a 3/16 bit for a project and this worked like a charm. I'm using this to organize the rest of them. Feels quite durable -- it's a thicker, hard plastic with no flex so it's not flimsy.... yet thin enough it will fit in my organizer bin. Frankly, all large sets of bits should come with one of these. Definitely worth the price for me.

This one does it all... measure drill bits in letters, numbers, fractions, and even metric. One word of advice, do as the directions say and stick the shank of the bits through the holes. The gauge is plastic and the sharp edges of the bits could damage the holes. Would be nice if they made this out of metal, though.

Same stuff they make printed circuit boards with.. The green plates! Has a great feel not like regular plastic. It has a core of fiberglass and is very rigid! Very precise and with a little care will last a lifetime. I have a stainless steel one that is unlegible and few holes. A plastic one that's OK? And an aluminum one purchased long ago. Very nice , but much less holes than this one. Without doubt this will be my go to unit. It also has a knock out for faster heads to measure length of screws and bolts. Loose that grip one the sweety roll of money! You won't regret it.

This is a great way to sort bits as it has the 3 gauges at once. Easy to read. Sure seems accurate.
