Wood Taps

A wood tap is a precision cutting tool that cuts internal threads directly into solid wood. It is used to create threaded holes for wooden bolts, vise screws, adjustable furniture hardware, and traditional joinery — applications where threaded wood is preferred over metal fasteners.

A metal-cutting tap can technically cut threads in very dense hardwood, but the geometry is wrong for wood grain. Metal tap threads are designed to shear metal and tend to compress and tear wood fibers rather than cutting cleanly. The Infinity Tools Wood Tap is specifically designed for wood's grain structure, producing cleaner and more durable threads.

Dense, close-grained hardwoods produce the strongest and most durable wood threads. Maple, beech, cherry, hornbeam, and boxwood are excellent choices. Softer or open-grained woods like pine or oak can be threaded but may strip under repeated loading; using a hardwood dowel insert in a softer wood is a common workaround.

Yes. Wood taps should be driven with a tap wrench or T-handle that gives you controlled, low-speed torque. Avoid power tools — threading wood requires a slow, steady feed with occasional back-turns to clear chips, and power driving risks splitting the wood or stripping the threads.

The pilot hole diameter depends on the tap size. Typically the pilot hole is slightly smaller than the thread's minor diameter. Refer to the thread chart included with the Infinity Tools Wood Tap Sets for the recommended pilot hole size for each tap in the set.

Traditional uses include workbench vise screws, hand-screw clamps, and chair stretcher joints. Contemporary applications include adjustable shelving, wooden hardware for hand-built cabinetry, custom jigs with threaded clamping pressure, and decorative wooden furniture with visible thread details.

For a complete threading system, you typically need both a tap (for the female thread) and a corresponding die (for the male thread on a wooden bolt or screw). Check the Wood Tap Sets product page for information on matched components, or contact us with specific thread size questions.

Use a correctly sized pilot hole (too small increases splitting risk), clamp the workpiece firmly, keep the tap aligned with the hole axis, and advance slowly with frequent back-turns to clear chips. Working in well-dried, defect-free hardwood also reduces splitting risk significantly.
