Has your driver bit ever destroyed the wood surface around a countersunk #4 or #6 screw? Standard Power Driver bits are sometimes too large to fit into a 1/4" diameter countersunk hole to drive a recessed screw. When that happens, the driver bit body makes a mess of the wood surrounding the hole. Normally, this is only a problem when using a 1/4" diameter countersink with #4 and #6 screws. The solution is quite simple - use a driver bit with a reduced shank. That way the bit tip can reach the screw without creating an unsightly mess. One-piece bits are usually a disappointing compromise between the need for a hardened tip and a durable body. A special Iso-Temp heat treating process makes these the toughest one piece bits available though, and their reduced shank nose can reach just a little farther into a countersunk screw hole without damaging the wood.

Comments about #0 x 1-15/16'' Reduced Shank Square Drive Bit Ball Detent:
Couldn't find a #1 square head driver in a big box store or hardware store. Even online you couldn't be sure you had a diameter than didn't exceed 1/4". McFeely's product description gave the detail needed to know I was buying the right size. The service was also great. Will buy again if I have another need for a hard-to-find hardware item.
Bottom Line Yes, I would recommend this to a friend

Why the long nose?
By JimBob (JB)
About Me Professional
Purchased to use on #0 square screws. Have plenty #1,2,&3s, but no #0s. The extended nose is ideal for recessing the screws to be followed with a plug or flush fill. Allows very small screws and deep recess. Long enough to prevent tearing the opening. Hardened tip ensures long-life and less rounded screw-head corners. #0s are hard to find, but McFeeleys is always on mark. Thank you.
Better Visibility and Better Reach
The reduced shaft design on these bits is primarily offered as a method to reach into counter bore holes for setting screws. Although I do use them this way occasionally, my primary benefit on the smaller sizes (#0 and #1) is the better visibility around the driver tip. Trying to see a small hinge screw head behind a 1/4" hex shaft driver is awkward. The reduced shafts remove this obstacle. And of course you get the usual high quality and great service that McFeely's has provided to me for years.
