Solid Tungsten Carbide Hinge Boring Bits That Keep Production Moving

In fast-paced joinery production, every second counts. Hinge boring, though a small step in the process, can quickly become a bottleneck if tool quality and precision aren’t up to scratch. Reworking poor-quality holes costs valuable time—and risks damaging high-end panels or hardware.

That’s where Leitz steps in.

Our solid tungsten carbide Z3/V3 hinge boring bits are designed specifically for CNC machines—built to perform under pressure, with accuracy you can trust.

Why Leitz Hinge Boring Bits Outperform

No More Rework: Precision-ground cutting edges and optimised spur geometry deliver clean, tear-free holes—even in tricky panel materials and decorative surfaces.

Fit-First Time: Boring diameter tolerances are tight and reliable, so hinges fit perfectly without trial and error.

Faster Production: With three cutting edges and efficient chip removal, Z3/V3 bits allow higher feed speeds and minimal downtime.

Longer Tool Life: The solid tungsten carbide construction holds its edge longer, reducing tool change downtimes.

Top 5 Tips for Perfect CNC Hinge Boring

Use a CNC-Optimised Bit:

Choose a boring bit specifically designed for CNC and multi-spindle machines. Leitz Z3/V3 bits maintain concentricity and edge sharpness—even at high speeds.

Prioritise Hole Quality Over Speed:

Fast feed rates are great—until poor hole quality causes rework. Choose tooling that delivers both speed and finish to avoid time-consuming manual fixes.

Minimise Fit Issues with Precision Tools:

Hinges must fit snugly—too tight or too loose will cause installation issues. Use tooling with exact tolerances to reduce errors and material wastage.

Maintain Machines and Collets:

Worn collets or poor machine setup can cause misaligned holes, even with the best tooling. Keep your CNC calibrated and clamping devices in top condition.

Choose a Bit That Lasts:

Constant bit changes stall production. A high-quality bit like Leitz’s Z3/V3 offers extended tool life—meaning more bored holes, less downtime.

When precision and productivity matter, Leitz hinge boring bits deliver. Designed for today’s joinery workshops, these bits eliminate rework, reduce waste, and keep your CNCs running at full speed.
