Kennametal’s KBDM face-milling system is designed specifically for abrasive automotive aluminium such as grades 319 and 390.

It employs a fine-pitch aluminium body with wedge-style clamps and adjustable pockets. A variety of PCD inserts is available, from mini-tips for light finishing cuts to full-face wipers, standard cartridge inserts and 12.7mm axial cutters for heavy roughing and shoulder cutting.

Developed for high volume machining, the KBDM is stocked in standard sizes of 63-200mm, although bespoke cutters up to 550mm in diameter can also be ordered. In addition, there are options for integral shank bodies, HSK mounting and left-hand cutter rotation, as well as special edge preparations and nose radii.

Kennametal recommends an initial cutting speed of 1 000m/min and feed rates of 0.01mm per tooth, although substantially higher values are said to be possible. With small diamond grains, KD1400 offers excellent chipping resistance. Using large diamond grains, KD1425 provides abrasion resistance.
