Make it Snappy Tools 40020 7-Piece Drill Bit Adapter Set, Use on Metal, Wood or Plastic, 1/16, 3/32, 1/8, 5/32, 3/16, 7/32 and 1/4 Inch Bit Size, Hex Shank Socket

Tip: The set includes 1/8”, 5/32” and 1/4” size collets which work great for many other things including Dremel bits, Rotozip bits, die grinder bits, carbide burrs, countersinks, wire wheels and many more items. By replacing the bits that come in the collet you can create things that aren’t available in the market, such as left-handed drill bits with a hex shank. Brad point bits... The combinations keep going. Just loosen the collets and replace the drill bits with anything with those size shanks. I would give a five stars if it included 135 degree split point drill bits not complaining. I manage a hardware store, so I’m well versed in the industry, but we don’t sell this brand so I was very happy to see them on Amazon.

Anybody that uses drills on a regular basis need these bits. Besides me loosing one of them, they are super. When regular shanked bits get dull we use them over and over and they work loosy. But if these get dull all you do is go to the hardware store and buy a new bit and replace the old. Since I often times use a countersink, I replaced the 1/4" drill bit with a countersink. Because of me loosing one and using the 1/4" one for a countersink, I decided to buy another set. Believe me you won't be disappointed with these bits.

The bits slip no matter how much they are tightened.I didn't use these immediately when I received them so I was past the return window by the time I figured out what a poor choice this was.I tried cleaning the bit, changing the bit to one I have, etc. but the collar would not hold them. This through soft wood too. Not even much of a challenge. Suggest you avoid these.

Great concept for all my cheap regular drill bits....these adaptors are great and will save me $$$ over buying the hex drill bits which cost more.Buying these adaptors and the cheap 100-250 assortment of drill bits will last me. (joinery carpenter) a lifetime and then some....I hope Snappy come out with adaptor that can accept larger round drill bits....the largest bit it can accept is slightly bigger than 1/4"

I've had a set of these for years, well made, dependable and I love that you can replace the bits. I just bought 4 more sets for the sons and sons-in-law in my life.

These are ok, not the best unfortunately. All is good except the bit wants to spin in the collet when the drilling pressure is too much. Very aggravating.Example, drilling through light sheet metal. As the bit starts to break through it will spin and then you get a jagged half hole.I used brake cleaner to remove all the oil material in the collet and bit, filed flat spots (opposite) on the shank of the bit and tightened the hell out of it. Helped some but still spins.I am not using unreasonably high amounts of pressure to make it spin. Will spin in wood as well.Magnetize the shank. The bit and shank will come out of the extension very easy. I bought these to swap from bit to Phillips or nut driver socket quickly. Did not make life an easier or faster.

I have found that the Snappy Drill Bit Adapters with replaceable drills to be more efficient than using the one peice hex head drills sold in the cordless drill kits. Using the Snappy Bit Adapters still allows the easy insertion and removal of the drill. It also allows the drills to be removed from the Snappy Bit Adapter for sharpening in the Drill Doctor where as the one peice hex head drills don't fit. Buying and replacing the drills in the Snappy Bit Adapters saves my company money and a kit is in every cordless drill case.

Very useful. Solid. Wash it and the drill with a solvent to remove lubricant residue. I found using something to rough up the drill shank a little is useful for a good grip. I would buy again if needed.
