Replaceable Drill Heads（HYK-GP WS8035）

Excellent drilling performance when machining cast iron, steel and under demanding operating conditions, such as poor machine rigidity and low spindle power.

Optimized groove geometry and unique straight-shaped chisel-edge design deliver outstanding centering capability, improving surface quality and dimensional accuracy of hole machining.

The unique chip-flute design provides superior chip breaking and chip evacuation performance, ensuring tool stability in deep-hole machining with a maximum drilling depth of 14×D.

Dedicated sub-micron grain blank substrate endows the tool with enhanced wear resistance. The AlCr-based composite coating features exceptional hot hardness and delivers outstanding wear resistance for machining cast iron and steel.
