New grooving insert from Horn


A six-edged, indexable grooving insert for turning has been added to the Horn family of carbide tooling.

Designated 64T, the precision sintered inserts are available with a grooving width of up to 3.29mm, with geometry .00. Grooving depths up to 3.5mm is possible and maximum workpiece diameter is 65mm.

As a neutral grooving insert, the 64T can be used on either the left or right hand holder measuring 16 mm x 16mm, 20mm x 20mm or 25mm x 25mm with internal cooling. A clamping screw system holds the insert accurately in the pocket ensuring rigidity and repeatability.

The new grade, EG55 high-performance coating considerably improves tool life and makes the grooving insert an effective all-round choice for machining most types of steel as well as a wide range of other materials.

Application areas being promoted initially are grooving and parting off for widths of 1.0mm and 1.5mm, turning circlip grooves from 0.57mm to 3.29mm wide, and grooving using full radius inserts with radii of 0.5 / 0.6 / 0.8 / 1.25 / 1.5mm.
