This pack of two 5/64" HSS twist drills replaces the pilot-hole bit in Snappy gold screw countersinks, letting you drill, countersink, and counterbore the correct hole for #4, #6, #8, #10, or #12 screws. These are drill-only replacements without a countersink body, sized for use with a 3/8" or 1/2" diameter counterbore -- handy for boring plug or dowel-button holes on their own.
- Drill size: 5/64" HSS twist drill (2-pack)
- Matches counterbores of 3/8" or 1/2" diameter
- Ideal for plug or dowel-button holes
- 1/4" hex shank works in power drills and quick-change chucks
Loosen the countersink's set screw to swap in a fresh drill, or use one on its own for boring plug and dowel-button holes.
