Buy Gripper Inserts: Supplier & Factories

Gripper inserts are replaceable, ultra-hard wear parts fabricated from cemented tungsten carbide (typically ISO K20–K30 grades like YG8 or YG11). Engineered with hardened serrated, diamond, or pyramid teeth, they are bolted, brazed, or dovetailed into CNC lathe chuck jaws and milling fixtures. Instead of relying solely on friction, they mechanically bite into raw castings, forgings, or bar stock to transfer maximum torque during heavy roughing without slipping.

Yes, custom engineered carbide solutions comprise over 65% of our daily production. Buyers simply supply 2D drawings (PDF, DWG) or 3D step files detailing dimensions, pitch angle, mounting hole counterbores, and working load conditions. Our engineering team reviews manufacturability within 8 hours and suggests customized powder recipes to optimize tooth impact life.

Tooth pitch and profile directly dictate penetration depth and holding force. Fine cross-hatch profiles (0.8–1.2 mm pitch) are engineered for pre-turned steel or finished parts where minimal indentation depth (less than 0.05 mm) is required. Coarse pyramid teeth (1.8–3.0 mm pitch) penetrate deep into rough, scale-covered castings and forged billets, providing dependable stability against heavy axial and radial tool paths.

Conventional sintering relies on capillary action to consolidate WC powder and cobalt, which can leave microscopic pores. Sinter-HIP applies 10 MPa of pressurized argon gas at peak sintering temperatures (around 1450°C). This high uniform pressure collapses internal micro-voids, significantly boosting transverse rupture strength (TRS) and preventing tooth chipping during violent interrupted cuts.

For standard stocked inserts and blanks, orders ship within 48 to 72 hours. Custom molded or CNC-ground tooling requires 15 to 25 business days. Flexible MOQs start as low as 20 to 50 pieces for prototype testing batches, scaling smoothly to thousands for continuous tier-1 supply. We coordinate global air express (DHL, FedEx, UPS) and DDP ocean shipping to destinations across North America, Europe, and the Asia-Pacific region.
