Magnum 7/16" x 7/16" x 4" HSS Tool Bit Blank (BHSS7164)
Eliminating chatter in large-bore internal work and heavy external turning is the primary advantage of the Magnum BHSS7164 7/16" x 7/16" x 4" Tool Bit Blank. The 7/16" (11.11 mm) square cross-section offers a massive footprint that bridge the gap between standard 3/8" and 1/2" tooling, providing superior rigidity for manual lathes. Constructed from premium high-speed steel (HSS), this blank maintains high red-hardness during bulk material removal cycles in cast iron and tough steels. The 4" (101.6 mm) overall length allows for secure mounting in heavy tool holders and provides significant material for multiple custom grinding profiles over the tool's lifespan.
Features
- Superior rigidity - 7/16" square profile provides stability for deep bores and turning .
