New KBDM face milling platform from Kennametal


The new face milling platform uses a fine-pitch aluminum body with wedge-style clamps and adjustable pockets. A variety of polycrystalline diamond (PCD) inserts are available, from mini-tips for light finishing cuts to full face wipers, standard cartridge inserts, and 1/2 in. (12.7 mm) axial cutters for heavy roughing and shoulder cutting.

There’s more to the KBDM than a robust body design. As automakers often create their own proprietary aluminum alloys, Kennametal has developed two PCD grades to complement it: KD1400 uses small diamond grains and offers excellent chipping resistance and good wear attributes, while KD1425 uses large diamond grains, giving it excellent abrasion resistance and thermal stability but only slightly lower performance where chipping is a concern. Both are capable of very high cutting parameters—depending on the alloy and setup rigidity.
