High-Density 1/2 Inch Impact Ready Step Drill Bit with 13 Steps and 132-Degree Split Point Tip

The Diablo DSD0500S13 1/2-Inch Impact Strong Step Drill Bit delivers an industrial sheet metal and plastic processing solution engineered to drill clean, concentric openings without structural material deformation. Forged with automated CNC-milled cutting steps and balanced by an optimized dual-flute geometry, this heavy-duty step bit executes clean penetration paths up to 2X faster than standard accessories while yielding a 6X extended service lifespan. The integrated 1/4-inch hex shank establishes an impact-ready platform that mounts securely into high-torque impact drivers and standard cordless drills, utilizing a self-centering 132-degree split point tip configuration that bites instantly on slick electrical boxes, HVAC ducts, and thick-walled PVC tubes to completely stop bit walking.

Best Used For:

  • Electrical Knockout Scaling: Expanding pre-punched holes or sinking clean knockouts directly into steel electrical junction enclosures and circuit breaker boxes.
  • HVAC Duct Venting: Drilling structural pass-through holes into thin galvanized sheet metal air ducts up to 1/8-inch thickness for probe routing.
  • Plumbing PVC Routing: Creating clean, burr-free fluid openings and attachment holes across rigid plastic pipes, PVC conduits, and composite panel materials.

Key Performance & Safety Features

  • 132 Degree Split Point Tip: Self-starting nose geometry anchors immediately onto metallic finishes to initiate fast cuts without center punching.
  • 6X Service Life Matrix: Advanced thermal-resistant steel treatment safeguards step edges against heat flattening to extend tooling runtime.
  • Debris-Clearing Dual Flutes: Precision dual-flute channel architecture accelerates chip evacuation to deliver continuous jam-free drilling.
  • 75% Cordless Efficiency Booster: Optimized mechanical balance reduces rotational cutting drag to secure up to 75% more drilled holes per battery charge cycle.
  • Laser-Etched Sizing Gauges: High-contrast crisp markings embedded within the steps provide instant visual tracking of achieved diameter depths.

Pro-Tip: When cutting large diameter holes through 1/8-inch steel electrical panels, cycle your impact driver trigger at a moderate speed and apply light, continuous downward friction. Letting the 132-degree tip match the natural rotation pace lowers thermal storage, keeping the cutting steps pristine for subsequent runs.
