Whiteside 8067774 4-Pc. Tapered Drill Bit and Countersink Set. Designed to bore a countersink for flat head screws and simultaneously drill a hole to perfectly match the screw size and length.
The 4-Flute, 82° Carbon steel Countersink Heads are designed to slip over the drill bit and are held securely with dual set screws which go down into the flutes. To adjust the drilling length, simply slide the head up or down the bit.
The matching Drill Bits have a tapered point to resist the rapid pull-in tendencies of gel-coat and other hard, thin materials; plus, they break through less abruptly, which helps reduce blowout on exit. These bits work in in wood, plastic, or aluminum. Whiteside Machine Company - Claremont, North Carolina.
