FAQ:

Q: What size is the countersink on a Milwaukee drill?

A: The Milwaukee #10 Countersink features a 3/16 in. Drill Bit. The pre-drill and countersink bits are designed for use in Milwaukee Drill Drivers. The 1/4 in. Quick Change Hex Shanks allow for quick size changes.

Q: What is the best countersink drill bit for wood?

A: If you ask us personally, then the ultimate choice, that we would recommend you is Countersink Drill Bit, Baban Countersink Drill Bit Set 6 Pcs 1/4โ€ Hex Shank HSS 5 Flute Countersink 90 Degree Center Punch Tool Sets For Wood Quick Change Bit 6mm-19mm only Sold by Moworve.

Q: What size drill bit for counter sinking screw holes?

A: This #10 countersink with 3/16″ drill bit, by Milwaukee, looks like it would be the perfect tool for pre-drilling and counter sinking screw holes. But on first use the Hex Shank broke loose.

Q: How do you adjust the countersink on a drill bit?

A: The countersink can be adjusted on the drill bit by simply loosening the set screws and sliding it out on the bit. I found it quite cool to find a flat machined on the bit to allow securing the countersink at 1 in. out on it, without damaging the cutting edge of the flutes of the bit.
