OSG carbide AD drill 4D type 8678090

[Features]
Next-generation general-purpose carbide drill that supports various processing machines, from small machines and high-performance machining centers to automatic lathes and lathes.
The new wavy flute shape and low center thickness design have achieved low thrust and stable torque.
By adopting "EgiAs coating", the wear-resistant layer suppresses wear, and the nano-periodic lamination prevents the propagation of cracks.

[Use]
Work material: low/medium/high carbon steel, alloy steel, tempered steel, cast iron, ductile cast iron.
