The GripEdge LDB3 is a 3/16" Left-Hand Twist Drill Bit engineered for reverse-direction drilling to remove broken bolts and studs. Constructed from M2 High-Speed Steel (HSS), this bit delivers exceptional hardness and heat resistance during demanding drill-out work. The left-hand cutting geometry bites into broken fastener remnants as it drills, frequently extracting the bolt during the drilling process before a separate extractor is required. Designed as a key component of the GripEdge G-FORS broken bolt extraction system, the LDB3 is purpose-built for A&P mechanics, MRO technicians, and automotive professionals.
