Magnum 3/8" x 3/8" x 4" HSS Tool Bit Blank (BHSS384)
Eliminating the need for specialized inserts, the Magnum BHSS384 3/8" x 3/8" x 4" Tool Bit Blank provides a highly rigid square platform for custom tool grinding. The 3/8" (9.53 mm) cross-section is a standard industrial size, offering the mass required to dampen vibration and resist deflection during heavy turning and facing operations. Manufactured from high-speed steel (HSS), this blank maintains its hardness at elevated temperatures, ensuring consistent performance in both alloy steels and non-ferrous metals. Its 4" (101.6 mm) length provides a robust footprint for tool holders and allows for decades of service in manual machine shops through repeated sharpening.
Features
- Standard square sizing - Fits most industrial tool holders for universal lathe use .
- Heavy-duty rigidity - 3/8" thickness resists deflection under aggressive material removal .
- Thermal stability - HSS construction maintains sharp edges under friction-induced heat.
