DFAS

High Efficiency Drilling Over a Wide Range of Applications

High efficiency counter boring in various types of applications with excellent chipping resistance.

Low cutting forces reduces burrs.
Due to its unique shape, it is possible to correct eccentric holes and cast holes with high accuracy.

Features

“XR” Point Thinning

Optimised chip control and load reduction

The thinned centre cutting edge generates a low resistance and thereby creates an optimum chip geometry for a smoother chip flow.

TRI-Cooling Technology for All Dia.

For machining stainless steel and titanium

Coolant flow is increased without reducing the rigidity of the drill. The extra coolant flow dramatically improves chip evacuation and dissipates cutting heat. This enables stable machining of stainless steel and titanium alloys.

Original Sharp Cutting Edge Shape

Suppression of Burrs

Strength is ensured by providing a flat land (gash) at the corner of the cutting edge, and by adopting a sharp cutting edge over the cutting edge, burrs are suppressed.

Cutting Performance

Cutting Edge Comparison When Machining Titanium Alloy Ti-6Al-4V

Provides stability even during high efficiency, continuous machining.

Comparision of Quantity of Holes on an Inclined Surface When Machining Stainless Steel SUS304

No tool wear even in the centre where the cutting speed is low. Tool life can be extended.
