I've always been very suspicious of tapered drills. The geometry of the drill does NOT match the geometry of a wood screw. The math, using the Forest Product Laboratory equations, indicates that holding strength is sacrificed. I needed to flush install 100 #6×¾" silicon bronze wood screws. So I went with the W.L. Fuller HSS countersink and stop collar. I decided to throw in the tapered drill as a lark, to experiment with, knowing I could always pull the Stanley Screw-Mate parts and put them into the countersink. After careful alignment of the parts for my screw size, I drilled a test hole and installed the screw. I extracted the screw, cut the wood in half, re-installed the screw to check for THREAD ENGAGEMENT. This is the key feature to look for. Instead of the engagement shown in the W.L. Fuller catalog, I found 100% Thead Engagement! I was thrilled! I did not expect that!! My suspicion is over. I used the tapered drill to install all 100 screws, leaving the Stanley Screw-Mate parts on the shelf. Well done W.L. Fuller

We purchased 1/8" and 11/64" diameter sizes of these drill bits for use in our production wood shop. They seem to be of high quality to us. We use them for #8 and #10 screw sizes, which is smaller than recommended. We did find out the 1/8" are a bit small, especially for hardwoods, but the 11/64" are perfect in our experience. In our opinion the sizes recommended on the chart are too large.

I've been using these bits for over 25 years and there are no better on the market.

The Fuller taper drill / countersink / plug system is superb.

Great for predrilling holes for wood screws, makes a great tight fit that is easy to drive screws into, no more guessing diameters and length or stripping screws
