Manufacturer information

Specification

Application

for cutting fit tolerances in through holes on modern CNC machines with steady tool and workpiece clamping up to 1300 N/mm².

Execution

7–8° left-hand spiral, extremely variable pitch and inner cooling, type B

Advantage

innovative cutting geometry ensures excellent dimensional accuracy and process reliability for very high cutting parameters
high-quality solid carbide cutting material and coating ensure a very long service life
Internal cooling ensures optimum chip removal

Notes

Make sure that tools are accurately and tightly clamped (ideally use a hydro-mechanical clamping chuck or precision collet chuck). Note: Please refer to dimension table.
