OSG EX-SUS-GDS 5.02mm Stub Drill Bit for Stainless Steel (Made in Japan):
- Technical Specifications: Drill diameter 5.02 mm, flute length 26 mm, overall length 70 mm, shank diameter 6.0 mm (h6 tolerance), premium high-vanadium cobalt high-speed steel substrate (HSSE / Super HSS), gold Titanium Nitride (TiN) physical vapor deposition coating, sharp high-helix flute angle 35° - 40°, 2-flute stub design, Product of OSG Corporation Japan.
- Engineered Specifically for Work-Hardening Stainless Steels: Optimized for SUS304, SUS316, duplex stainless, titanium alloys, mild steel, and copper without work-hardening the hole bottom.
- Short Rigid Stub Geometry (26mm Flute): Extremely high torsional rigidity eliminates drill wandering and breakage on CNC machining centers and swiss-type lathes.
- Titanium Nitride (TiN) Gold Hard Coating: Reduces friction coefficient, dissipates extreme drilling friction heat, and prevents chip welding onto the cutting lips.
- High-Helix 35-40° Flute Geometry: Rapidly evacuates stringy stainless steel chips from the hole, ensuring mirror-smooth hole wall finish up to 1400 N/mm² tensile strength.
- Applications: CNC precision machining, aerospace medical fittings, food-grade stainless fabrication, and hydraulic manifold drilling.
