Bromsgrove-based Walter GB Ltd (www.walter-tools.com) has launched the new G3051-P groove-turning holder with MX22-2L/R Tiger.tec indexable inserts, specifically for grooving along a shoulder.

These inserts offer widths of 1.5-3mm and can produce depths up to 6mm. Designed for use on CNC, multi-spindle and auto lathes, the grooving system can be used on a wide range of components, from precision parts for medical devices to automotive camshafts.

The holder is available in shank sizes of 12 to 25mm and features precision cooling. Inserts are positioned at a 3deg incline; and because there is a ‘level design’ on the working face (as left- and right-hand versions), there is no end-face axial contact.

The four-edged inserts are available with the new GD8 and VG8 geometries, the latter being specifically developed for finishing operations behind a shoulder.

Other features of the inserts include a large contact surface and patented dowel-pin insert location (these features provide a high degree of stability, precision and indexing accuracy); there is also a tangential positioning arrangement that results in “outstanding flatness and surface quality in machining, as well as long tool life and therefore cost efficiencies”.
