The locking hole knife for tenoning machines cuts the lock holes in solid wood and board, with cutting diameters from 6 to 22 mm on 12.7 or 16 mm shanks and overall lengths from 110 to 190 mm, as listed in the specifications table.

Design and Construction

The locking hole knife pairs a solid PCD cutting edge with a steel shank sized for the tenoning machine’s chuck. Each part number fixes the cutting diameter, shank and overall length for the lock-hole position.

How It Works

The small PCD head plunges and cuts the locking hole in one cycle; the edge holds its diameter in abrasive hardwood and engineered board, keeping the hole consistent for the hardware.

Applications

• Lock hole cutting on tenoning machines
• Hardware preparation in solid wood
• Frame and door machining
• Panel furniture lock positions

Suitable Materials

• Solid wood
• Engineered board
• Hardwood frames

The PCD edge holds the hole diameter through long runs in abrasive hardwood.

Material Comparison: PCD vs. Tungsten Carbide

The figures below are typical industry data for production woodworking. PCD does not replace carbide in every job — carbide remains the right choice for low-volume general work — but on abrasive sheet goods the difference in blade life is decisive.

Figures are typical published values; actual blade life depends on the workpiece material, feed rate, depth of cut, machine condition and maintenance schedule.

Delivery Scope

Single blade. Order by part number with the diameter, bore, width and tooth count stated in the specifications table below.

Why Choose VPOINT

• One-year warranty on every blade — defects in material or workmanship are covered for 12 months from delivery.
• Custom tooling — diameters, kerfs, bores and tooth counts built to your drawing or sample.
• Non-standard fabrication — sizes outside the standard catalogue, including bore re-sizing and tooth-count changes.
• Resharpening service — blades return to service after regrinding at a fraction of new-blade cost.
• Factory-direct since 2008 — ISO 9001 manufacturing in Sichuan and Dongguan, China; 40Cr chrome-molybdenum steel bodies; no trading intermediaries.

Send a drawing, a sample or a worn blade, and our engineering team will quote the exact specification you need.

Precision & Quality Control

Every blade is inspected before shipment. Outside diameter, kerf thickness, plate thickness, bore diameter and tooth count are measured against the values listed in the specifications table, and tooth geometry (hook angle, bevel angle) is verified against the design drawing. Blades are stress-checked for runout and tension before packing.

Blades measuring outside tolerance do not ship. Inspection is performed under our ISO 9001 quality system, with batch records retained for traceability.
