Revolutionary Machining of Hardened Steels

New coating provides outstanding tool life

IMPACT MIRACLE REVOLUTION Coating

The combination of the newly developed(Al, Cr, Si)N coating with improved lubricity and a high oxidization temperature, together with the (Al, Ti, Si)N coating layer which provides excellent wear and adhesion to inner coating layer, enables efficient and reliable machining of hardened steels.

Due to manufacturing adjustments, differences in the color of the coating for different diameters may occur. This has no adverse effect on performance.

Precision-Corner Radius End Mill, 4 Flute

VFRPSRB

High precision machining is achieved via a seamless shape that suppresses chipping, a strong back taper that reduces chatter and a wiper blade providing improved surface finish.

vfr_14_en-us.png

High-Precision Corner Radius Accuracy

The corner radius of VFRPSRB is measured as follows, based on the absolute centre of the corner radius.

Completely Seamless Curved R Edge, DC≥1.5mm

A stable machined surface is achieved by a seamless blend between the radius and flank geometry.

vfr_16_en-us.png

Equipped with a Wiper Edge, DC≥1.5mm

A glossy surface finish is possible via the inclusion of a wiper edge.
