PREMIUM THERMAL-RESISTANT DRILLING LINE

HSS DRILL BITS (GOLDEN) SERIES

Heavy-Duty High Speed Steel Golden Flute Twist Drill Bits

Minimize heat spikes, maximize cutting speeds, and secure clean concentric boreholes with the enhanced durability of the Industrial HSS (Golden) Twist Drill Bit Series. Forged from high-grade High Speed Steel (HSS) and treated with a specialized low-friction golden surface coating along the cutting flutes, these standard jobber-length straight-shank bits excel under high operational torque. Engineered for demanding industrial metal drilling, structural alloy fabrication, seasoned timbers, and high-density polymers, the dual-tone spiral configuration accelerates debris clearance to safeguard against point-dulling. Featuring an extensive size index spanning fractional diameters from 1/64″ to 1/2″ profiles alongside a robust metric range running from 1mm through 13mm engineering sizes, this elite lineup delivers heavy-duty reliance for high-volume automotive setups, commercial engineering floors, and bulk wholesale distribution networks.

Engineered Benefits

✓ Advanced Golden Flute Coating: Features a friction-reducing layer along the spiral grooves that shields the cutting edge against thermal failure, extending operational life during dense material runs.

✓ High-Precision Parallel Shank: Designed with standard uniform cylindrical shanks for uniform concentricity and secure clamping in standard keyed or keyless industrial chuck assemblies.

✓ Commercial B2B Bulk Packaging: Structured seamlessly into 50 or 100 piece inner cartons and heavy-duty master boxes (up to 5,000 units) to guarantee secure, high-density bulk storage logistics.
