Our new Serra Bites were designed for Orange vise 4th axis users looking to push the limits of low grip height work holding. These bites have just under 1/8th of an inch of grip height and a newly designed serration patter specifically for long stick out forth axis work as well as customers who are holding on to harder materials. They also feature a reversible option of a flat back for customers who do not want to leave marks in the part or second operation 4th axis work. They are made from all American A2 tool steel hardened to 60rc and will work in materials as hard as 40Rc. Sold in sets of 4 with all mounting hardware included.
