Professional Metal Drilling: All-in-One Bit Solution for Stainless and Hardened Steel

Use the Diablo Tools DMD-S15T drill bit set for professional-grade performance in mild, hardened, and stainless steel applications. Engineered with a proprietary Thermal Shield Protective Coating and an automated CNC-ground 130-degree split point tip, this 15-piece set delivers up to 30 times longer life than standard titanium or cobalt bits while ensuring accurate, on-point starts. The optimized flute geometry enhances debris removal to maintain lower tip temperatures during high-speed operation. 

Best Used For:

  • Precision Metal Fabrication: Creating clean holes in stainless steel, cast iron, and sheet steel with zero wandering.
  • Hardened Steel Machining: Drilling through high-density hardened alloys where standard drill bits fail due to heat buildup.
  • Mixed-Media Construction: Efficiently transitioning between metal, wood, and plastic materials on diverse job sites without changing bits.

Key Performance & Safety Features

  • Thermal Shield Coating: Advanced multi-layered barrier protects the bit tip against heat, significantly increasing tool longevity.
  • 130-Degree Split Point: Unique geometry enables immediate, accurate drilling starts without the need for center punching.
  • Optimized Flute Geometry: Engineered to eject metal shavings rapidly, reducing heat transfer to the bit and workpiece.
  • 3-Flat Shank Design: Securely fits into standard drill chucks to eliminate bit slippage during high-torque applications.
  • CNC Precision Grinding: Automated manufacturing process ensures strict industrial angle tolerances for faster, more accurate hole drilling.

What's Included

  • (15) Metal Demon Drill Bits: 1/16", 5/64", 3/32", 7/64", 1/8", 9/64", 5/32", 11/64", 3/16", 13/64", 7/32", 15/64", 1/4", 5/16", 3/8".
