HSS Square Toolbits are precision cutting tools manufactured from premium High Speed Steel (HSS), designed for a wide range of turning, facing, chamfering, threading, grooving, and general machining operations on lathes. Their square cross-section provides excellent rigidity and stability, allowing the cutting edge to be ground into various profiles for custom machining requirements. With outstanding toughness, wear resistance, and heat resistance, HSS square toolbits deliver consistent cutting performance, superior surface finish, and extended tool life across a variety of engineering materials.
