The IRWIN 66708 is a 6-inch aircraft extension drill bit engineered for high-performance drilling in hard metals and confined spaces. Manufactured from premium high-speed steel with a black oxide finish, this bit provides enhanced heat resistance and durability for demanding industrial applications. The 135-degree split point geometry ensures immediate penetration and prevents the bit from walking on the workpiece surface, eliminating the need for a center punch. With a 1/8-inch diameter and a 1-5/8-inch flute length, it offers the extended reach necessary for deep-hole drilling while maintaining structural rigidity. This heavy-duty bit is ideal for aerospace, automotive, and general construction tasks where standard-length bits are insufficient.

M-2 high-speed steel for strength with black oxide coating for heat and wear resistance in wood, metal or plastic applications. Split point ensures a true start and eliminates bit walking.
