Snappy Tools 5/16 Inch Quick Change Drill Bit Adapter #42020

Good little item. But wish it would be made of stronger material

I became frustrated with the inability of most drill chucks to securely hold a drill bit. Too often, the bits simply "grabbed" the work and spun within the chuck, even though I had applied the most amount or torque I could muster using the chuck's key. For a time I tried some of Milwaukee's SHOCKWAVE(tm) Hex Drill Bits. These bits were good in the sense that they did not slip when securely fastened in a chuck, moreover they could also be used in an impact driver.On the downside, hex drill bits were extremely costly when compared to standard (round) jobber bits. Despite Milwaukee's claims, I found that their hex bits became dull relatively quickly. On one particularly difficult job I went through 3 hex bits in about a half hour. I simply couldn't afford to continue down that path. After some extensive research I came across Snappy's drill bit adapters. They were exactly what I was looking for. The drill bit adapters use a collet to hole the drill bit. I found this approach to be superior when it comes to preventing the bit from slipping. Occasionally a jobber bit will slip within the collect, however this is easily correctable. Simply remove the adapter from the drill/driver. Place the hex end in a vice and tighten the collet nut with an adjustable wrench or appropriately sized combination wrench. Problem solved.The other major advantage to Snappy's drill bit adapters are their cost. A single Snappy drill bit adapter is less expensive than a comparably sized Milwaukee or DeWalt impact drill bit at any of the major box stores. Moreover, if the bit held in the collet adapter becomes dull or broken, it can easily be replaced. The owner is also free to buy as good a drill bit as he or she feels is necessary. I plan to buy the entire Snappy Drill Bit Adapter Set as soon as I can.

These collets are excellent. I chuck it up in my DeWalt impact and a moment later I either have a hole or a shattered drill bit. It drills about 4 times faster, and eliminates the jammed up bit when it breaks through due to the impact mechanism hammering the bit. I've been using them almost a year now and have never had a bit spin in the collet. Also there's 180° twist in the collet shaft from the impact yet it has not broken nor does it show any sign that it will. Only problem is my coworkers are always borrowing it and don't want to give it back. Until the bit wears our or breaks....

Usual excellent Amazon delivery service and prompt refund on request. I bought the adapter because I liked the design and wanted to give it a try. It seemed to be a solid tool and well made. I suspect the design would have been flawless made for smaller bits. For further explanation, I was trying to adapt a 3/8" Kreg step drill for the pocket hole jig so that it could be a quick change drill bit. The Kreg bit is mirror finished on the shank and my first attempt didn't quite bite the bit enough to keep it from spinning in the adaptor. My second attempt worked with hard pressure from two wrenches. Could be the 1/4" quick change stem is not enough leverage to counter the larger nut for compressing the split arbor. I was not sure it would serve so I asked for a refund.

These adapters allow you to buy less expensive "regular" quality drill bits and make them a quick change bit. I have 2 full sets of these adapters, one for wood with brad point drills and another for metals. Every Snappy Tools tool I have works great and is well made.

Worked great and shipping was fast. Gets used constantly and these snappy quick change last at least 3 months doing sheet metal.

Did not work with 1/32” bit. It was too loose to grab the bit, even after using pliers and wrench to tighten collet piece. I expected more from Snappy.

THESE ARE FANTASTIC!!!I misplaced my previous adapter after using it for +10 years in the sheetmetal trade. The new adapter is drilled completely through the stem allowing you to use double ended bits. Now you can clear broken chunks of bits out of the adapter!!! I had a chunk stuck in my old one FOREVER!
