YDTech® manufacturer of hardmetal wolfram WC driving pins for face clamping,turning, milling! supplier of custon tungsten carbide face drive pins on workholding for drilling, grinding.

standard steel drive pins work well for most turning and grinding applications. However, when workpiece hardness exceeds 40 HRC, steel pins often fail. They struggle to bite into the material, leading to slippage, torque loss, and excessive heat generation. The result is premature wear, damaged drive pins, and scrapped parts.

It is important to ensure that the direction of rotation of the face drive is correctly aligned with the spindle to avoid any potential damage to the workpiece or the face drive itself. Always refer to the manufacturer's instructions and guidelines to ensure that you are using the face drive correctly and safely.

We use premium tungsten carbide blanks, precision ground and vacuum‑brazed or mechanically clamped to hardened steel bodies. Each pin is inspected for dimensional accuracy (±0.005 mm) and surface finish. Our hardness and toughness specifications guarantee reliable biting force even on workpieces exceeding 50 HRC.

to define the direction of rotation of the face drive, you need to identify the direction of rotation of the spindle of the lathe or machining center that the face drive is attached to.
