Inserts

WBH20C WL25 indexable inserts are full-radius copy turning inserts with Walter Lock positive engagement. The WL positive engagement provides maximum stability and precision for reliable machining of contours. With pocket support right under the cutting edge, and exceptional ability to prevent vibrations; the WL positive engagement is substantially better than the conventional V-shaped or even full radius grooving inserts.

The coating’s mechanical post-treatment induces a unique state of residual stress in the layer surface, which in turn increases process security. The DRAGONSKIN grade CTCP425-P with advanced AL2O3-TiN CVD coating is particularly well suited for when uninterrupted cuts are required. It delivers excellent wear resistance even at increased cutting speeds.

KBN020 excels as a 1st choice, general purpose CBN grade with a broad application range from continuous to heavily interrupted machining. Utilizing innovative new layering techniques, Kyocera has developed the MEGACOAT TOUGH coating technology. This coating combines a highly wear-resistant layer on the surface adhered to high-content CBN which is used to toughen up the edge for greater fracture resistance when encountering interruptions.

DoMultiRec multifunctional milling cutter with center cutting capability enables a single tool to perform multiple milling operations, including shouldering, pocketing, and drilling. The DoMultiRec inserts to ensure strong and sharp cutting edges during various milling and drilling operations.

A PVD-coated cemented carbide grade, AH8015 features an extremely hard high-aluminum content multilayer coating that is combined with a tough dedicated carbide substrate. The grade provides the insert with a well-balanced wear and chipping resistance.

To cover the widest possible range of applications, Walter offers the MP6 geometry in CCMT, DCMT, TCMT and VBMT basic shapes. Its short protective chamfer, which is characteristic of roughing inserts, ensures a high strength of cutting edge, even in challenging conditions, for example when machining forged parts or components with interrupted cuts. The 18° positive rake angle ensures excellent chip control during medium machining.

Together with successful AH7025 grade for first choice, AH6235 and AH8005 grades will enhance TungCut performances in parting and grooving operations with interruptions, as well as grooving and turning operations with aggressive conditions.

AddInternalCut inserts are available in two sizes: TCIG10 insert is for internal grooving of minimum bore diameter of 10.5 millimeters (.413 inches) and up. TCIG12 allows a maximum groove depth (CDX) of 3.0 millimeters (.118 inches).

SDM chipbreaker features unique T-land with variable widths and optimized rake angle that provide the insert with resistance against notch wear. Difficult metals like HRSAs are prone to cause notch wear on the insert cutting edge that can severely deteriorate insert tool life. A combination of SDM geometry and the AH8000 grade series will substantially extend tool life and provide superior predictability.
