The carbon steel bit is precision-ground to ensure smooth chip evacuation, while the high-speed steel chisel body maintains a sharp edge even under high-production demands.Performance Features Precision Geometry: Carefully ground edges provide clean-walled square mortises without the need for manual cleanup. High-Speed Steel (HSS): High-grade HSS construction provides superior heat resistance and edge retention compared to standard carbon steel. Universal Compatibility: Features a standard 3/4" (19mm) chisel shank that fits most benchtop and floor-standing mortising machines. Optimized Chip Clearance: Large side openings in the chisel allow for rapid chip removal, preventing overheating and binding during deep cuts.
