Description

Unleash Cordless Performance: Diablo SPEEDemon 1-1/2 Inch Self-Feed Bit

Redefine productivity on the jobsite with the Diablo DSF1500 1-1/2 in. SPEEDemon™ Self-Feed Bit. Engineered to meet the exacting standards of professional electricians, plumbers, and HVAC contractors, this bit features a precision heat-forged construction that delivers superior durability and consistency. The advanced 2-cutter head design is optimized for energy efficiency, requiring less power to drive through material. This innovation allows you to drill up to 2X more holes per battery charge, making it the perfect companion for your high-performance cordless drills and impact drivers.

The DSF1500 excels in speed thanks to its aggressive low-thread count feed screw, which pulls the bit effortlessly through softwoods while preventing pitch build-up. Diablo has also addressed a common frustration with its exclusive pull-out stop mechanism, designed to keep the feed screw securely in place when withdrawing the bit from deep holes. Equipped with a robust 7/16-inch hex shank, this bit ensures a secure, slip-free connection in 1/2-inch chucks, delivering the torque transmission needed for fast, clean hole making in clean wood.

Key Features

  • Forged Durability: Heat-forged from premium steel on automated equipment for strict tolerances and up to 2X longer life.
  • Cordless Optimization: Energy-efficient 2-cutter geometry delivers up to 2X more holes per battery charge.
  • Rapid Feeding: Aggressive low-thread count feed screw resists pitch buildup for faster drilling speeds.
  • Secure Feed Screw: Pull-out stop design prevents the screw from slipping out or getting lost during bit removal.
  • Clean Cuts: Balanced cutting head produces smooth holes with minimal vibration in softwoods.
  • High-Torque Shank: 7/16" Hex shank eliminates slippage in drill chucks for maximum power transfer.

Pro-Tip: The 1-1/2" diameter is the ideal size for running 1-inch schedule 40 PVC pipe (which has an outer diameter of approx. 1.315"), leaving just enough wiggle room for adjustments without compromising the stud structure. Because self-feed bits pull aggressively, always use the auxiliary handle on your drill to safely manage the torque.
