Magnum 5/16" x 5/16" x 4" HSS Tool Bit Blank (BHSS5164)
Maximizing tool life in medium-duty lathe work requires the balanced cross-sectional strength of the Magnum BHSS5164 5/16" x 5/16" x 4" Tool Bit Blank. This high-speed steel (HSS) square blank is engineered to bridge the gap between small detail tools and large roughing bits, providing sufficient mass to counteract radial cutting forces during turning. The HSS grain structure allows for grinding a highly refined edge, making it suitable for both bulk material removal and achieving superior surface finishes on varied workpieces. Its 4" (101.6 mm) length ensures compatibility with standard quick-change tool posts while offering extensive material for custom profiling.
