Key Features & Benefits

• High-Speed Steel (HSS) Construction: Crafted from premium-grade steel that maintains sharpness even under extreme temperatures, ensuring longer bit life and consistent performance.
• 118° Standard Tip Angle: Optimized for versatile drilling across metals (steel, aluminum, cast iron) with reduced walking and faster penetration.
• High-Precision Grinding: Laser-measured cutting edges provide burr-free holes with ±0.1mm accuracy – ideal for precision engineering tasks.
• Optimized Flute Design: Spiral grooves efficiently remove metal shavings, preventing clogging and overheating during prolonged use.
• Universal Shank Compatibility: 9mm hex shank fits all standard drill chucks, including impact drivers and magnetic drill presses.

Why This Drill Bit Set Outperforms Others

Unlike generic drill bits that dull after minimal use, Surbahla's HSS metal drill bits undergo triple-tempering for 300% increased wear resistance. The micro-grain structure ensures stability when drilling through hardened steel up to 65 HRC. At 81mm working length and 125mm total length, these bits offer deeper reach than typical hardware store options while maintaining rigidity.

Professional-Grade Applications

These industrial-strength drill bits solve critical challenges for:

• Metal Fabricators: Create clean holes in steel plates without expensive step drilling
• Automotive Technicians: Drill through suspension components and exhaust systems without bit breakage
• HVAC Installers: Effortlessly penetrate galvanized steel ducts and brackets
• Home Workshop Users: Tackle metal shelving, tool modifications, or hobby projects with professional results

"What's the best drill bit for stainless steel?" Our customers confirm these bits outperform cobalt alternatives for 304/316 stainless at 1/3 the cost.
