Iscar Metals Inc. offers a family of reinforced TANG-GRIP blades for the INDEX Model MS18C and TRAUB TNL and TNK mill/turn machines. The blades are suitable for parting and grooving between the main spindle and subspindle. Because of their reinforced construction, the blades can be applied in long-overhang applications. Only the part of the blade needed for penetration has a reduced width. The rest is thick, which improves rigidity and stiffness, according to the company.
