11-piece countersink drill bit set for woodworking

This 11-piece set includes countersink bits sized for #4, #6, #8, #10, and #12 screws, along with five replacement drill bits, an Allen wrench, and a storage case. It is designed for woodworkers, cabinet makers, and DIY enthusiasts who need accurate pilot holes for flush or hidden screw installation. The titanium-coated steel construction suits general workshop use.

Sustained drilling performance with chip removal

Dual-edge spiral blades on each cutter head provide faster, smoother drilling and effective chip evacuation during continuous use. This design prevents clogging and residue buildup inside the hole, maintaining clean cutting action over longer sessions. The manufacturer notes the set is not recommended for prolonged use on hardwood to preserve bit life.

Titanium-coated M2 steel with 1/4-inch hex shank

Pilot bits are made from M2 high-speed steel with a titanium coating for improved hardness, wear resistance, and long-term sharpness. The 1/4-inch hex shank allows quick, secure bit changes on hand drills, electric drills, and bench drills. An adjustable depth collar, set with the included wrench, gives consistent depth control for flush-mount or hidden screws. Buyers who need countersink sizes beyond #4 to #12 or bits rated for heavy hardwood production should look elsewhere.

Questions about this item

Does the titanium coating on the 11-piece countersink set reduce heat buildup during extended drilling in wood?

The titanium coating on the M2 high-speed steel bits improves hardness and wear resistance, which helps maintain sharpness and reduces friction during prolonged use in softwood, plywood, and plastic.

What drill chuck size is needed to use the 1/4-inch hex shank on these countersink bits?

The 1/4-inch hex shank fits standard drill chucks and quick-change adapters on hand drills, electric drills, and bench drills.

Will the adjustable depth collar on the #4 through #12 bits work with older drill presses that have limited quill travel?

The adjustable depth collar is set with the included Allen wrench, allowing precise depth control regardless of the drill press quill travel.
