Fuller Countersink for Hardwoods - 1/4 in. Dia.

Fuller countersink for hardwoods (1/4 in. diameter)

A Fuller countersink for hardwoods (1/4 in. diameter) is a precision woodworking bit designed to drill a pilot hole and create a clean countersink in one operation—ideal for hardwood applications where tear-out and splitting are concerns.

Key Features

• 1/4 in. diameter pilot – sized for screws with a 1/4" shank or similar applications
• Adjustable countersink collar – lets you control screw head depth for flush or recessed finishes
• Hardened steel construction – built to handle dense hardwoods like oak, maple, and cherry
• Replaceable/tapered drill bit – reduces splitting and improves holding strength
• 4-cutter design (common on Fuller bits) – produces smooth, chatter-free countersinks

Benefits

• Drills pilot hole and countersink in one step (saves time)
• Leaves a clean, professional finish in hardwoods
• Helps prevent wood splitting and screw breakage
• Consistent screw depth for repeatable results

Typical Uses

• Cabinetmaking and fine furniture
• Hardwood joinery
• Installing hinges, hardware, or face frames
• Any project where flush or plugged screws are needed

Pro Tips

• Use moderate drill speeds to avoid burning hardwoods
• Back the bit out occasionally to clear chips
• Pair with matching wood plugs if you want a concealed fastener look
