1.Left hand drill bits are ideal for extracting broken, righthand threaded studs and bolts.Designed for use in reversible

drills, lathes and milling machines.
2.Unlike right handed drill bits, the drilling action will assist to loosen sheared off bolts or studs rather than tightening them

further.And made for drilling into hardened steel bolts for creating pilot holes for screw extractors.

sheared bolts and studs
4.135-degree split point reduces feed pressure and allows for easier penetration without work hardening.
5.HSS-Co drills are ideally suited for materials that are especially difficult to drill such as stainless steel and for higher chip loading.
