Piloted-Countersink-Bits Published December 12, 2012 at 340 × 266 in How to Select Woodworking Countersink Drill Bits for Flush-Set and Plugged Screws It’s rare to find the old-style flat steel piloted countersink bits, but they are great for drilling countersinks quickly (if inefficiently).
Would like to order a set of “old” style, flat steel, piloted,countersink drill bits.
