The 4-Piece Countersink Bit Set gives you the core sizes needed for clean, accurate screw installation in woodworking, cabinetry, furniture building, and general shop projects.

This set includes #6, #8, #10, and #14 countersink bits, each paired with a tapered drill bit to help create a properly sized pilot hole for wood screws. The tapered drill design helps reduce splitting, improves screw holding strength, and allows the screw to seat cleanly without forcing or tearing the surrounding material.

Use these bits when installing hardware, assembling cabinets, building jigs, fastening trim, or any project where you want screws to sit flush or slightly below the surface. The countersink cuts a clean recess for the screw head, while the tapered pilot hole helps guide the screw and support a tighter fit in wood.

Includes:

#6 countersink with tapered drill bit
#8 countersink with tapered drill bit
#10 countersink with tapered drill bit
#14 countersink with tapered drill bit

Ideal for hardwoods, softwoods, plywood, MDF, cabinet parts, furniture components, and general woodworking applications.

Customer Reviews (4.6 / 5 · 5 reviews)

Olivia ★★★★★

Drilled a few test holes in some oak scraps and the clean, chip-free finish surprised me. The #8 bit sits perfectly flush, exactly what I needed for cabinet hardware.

Elizabeth ★★★★★

The #6 and #8 sizes are the only ones I reach for in most builds, and the cutting edges are sharp enough to leave a clean recess without tear-out. I used them on some oak drawer fronts and the screws sat perfectly flush with zero fuss.

Penelope ★★★★★

Sizes #6 and #8 cover the screws I actually use for cabinets, and the bits stay centered in my drill chuck without wobbling. The cutting edges are sharp and crisp right out of the box.
