GHSX Endmills

GHSX Endmills USES high-wear-resistant and heat-resistant GHSX coatings to improve reliability and long tool life in a wide range of working materials. The combination of the big dip and the distinctive flute profile helps to improve sharpness and chip evacuation. By inhibiting the change, the outer diameter tolerance is reduced by 2/3. Compared with the traditional method, the diameter adjustment is not required when replacing the tool. GHSX has high surface precision with high rigidity, long cutting edge length (4D)/ >

GHSXVL vibration type

The optimal irregular spacing of GHSXVL and irregular lead can greatly improve the grinding force and anti-fracture performance, and achieve high speed, high feed and low cutting force. GHSXVL realizes the round land, greatly improves the processing surface quality.

(circle phi 5mm or more.)

GHSXB Ballnose

The combination of ultrafine carbide substrates with new coatings improves heat resistance and wear resistance. GHSXB reduces the cutting force and has a strong helical angular R cutting edge. GHSXB improves the ability of the chip to evacuate through its unique pocket shape + widened pocket area.
