Ultimate Durability for the Trades: Diablo 7/8 in. Impact Strong Step Drill Bit

Bring exclusive technology and unmatched efficiency to your jobsite with the Diablo DSD0875S12 Impact Strong Step Drill Bit. Engineered specifically for the rigorous demands of electricians, plumbers, and HVAC contractors, this tool is the premier choice for making fast, accurate holes in thin metals, PVC, and other plastics. At the core of its performance is the innovative 132° Split Point Tip, which eliminates the need for a center punch and prevents "walking," ensuring a precise start every time. This advanced geometry not only speeds up the workflow but also stays sharper longer, offering up to 6X the lifespan of standard step bits.

Designed for maximum versatility, this 12-step bit features an automated precision CNC grinding process that guarantees strict angle tolerances, resulting in smooth, jam-free cuts that are 2X faster than the competition. The optimized dual flute design efficiently clears debris, while the laser-etched markings provide instant visibility of hole sizes, even in low-light conditions. Equipped with a 1/4-inch hex shank, this bit is impact-ready, allowing you to switch seamlessly between standard drills and high-torque impact drivers for 75% more holes per battery charge.

Key Features

  • 6X Longer Life: Advanced Split Point Tip withstands wear and stays sharper significantly longer than standard bits.
  • Precision Speed: Automated CNC grinding delivers consistent angles for 2X faster drilling speeds.
  • No Pre-Drilling: 132° tip starts on contact without walking, making center punches obsolete.
  • Impact Ready: 1/4" Hex shank provides superior grip and stability in both impact drivers and drill drivers.
  • Jam-Free Cuts: Optimized dual flute geometry ejects chips and debris rapidly.
  • Cordless Efficiency: Engineered to provide up to 75% more holes per battery charge.
  • Clear Markings: Steps are laser-etched for easy identification of hole sizes up to 7/8".

Pro-Tip: To extend the life of your step bit even further, apply a small amount of cutting fluid or wax stick to the bit before drilling into metal. This reduces friction and heat buildup, which are the primary causes of dulling, ensuring your bit cuts like new for longer.
