Order # LT4PLT-1, Tough Duty Piloted Taps for L4 Stitching Pins

We designed this new piloted tap (U.S. Patent number 5,562,371) to help keep the tap aligned to the drilled hole. The L4 and L6 taps are made of CPM-M4. Improper tap alignment is the number one cause of broken taps. You can do a lot to eliminate that cause with this extra bit of insurance.
