SPECIALS

High Performance Regrinds : High Performance inserts should be reground and coated by Allied Machine before returning them to production. The real economy of High Performance spade inserts is their improved production rates (100% and 500%) and increased tool life (3 to 20 times). Factory regrinding and coating provides like-new tool performance. Our factory service reduces your total cost-per-hole.
