Simplify Jobsite Drilling with One Versatile Solution

The Bosch SDH30 3-Piece High Speed Steel Step Drill Bit Set is the ultimate multi-tasking solution for electricians, plumbers, and HVAC contractors. Designed to eliminate the need for carrying multiple drill bits, this set allows you to drill clean, accurate holes in up to 13 different sizes using just a single bit. Whether you are performing electrical knockouts, running conduit, installing faucets, or working on auto body repairs, these bits power through thin materials up to 1/8-inch thick, including sheet metal, ducts, stainless steel, copper, brass, plastic, and even plexiglas.

Engineered for professional performance and longevity, these step drills feature a self-starting point that grabs on contact, preventing the bit from "walking" across the surface. The balanced double-flute design ensures smooth operation by eliminating chatter and vibration, resulting in perfectly round holes every time. Additionally, the bits are equipped with a three-flat shank that locks securely into your drill chuck to reduce slippage under high torque. With re-sharpenable cutting edges, this set provides lasting value and reliability for the most demanding applications.

Key Features

  • Versatile Performance: Drills multiple hole sizes with a single bit, perfect for electrical, plumbing, and HVAC work.
  • Self-Starting Tip: Starts on contact without a center punch and prevents skating on smooth surfaces.
  • Smooth Operation: Balanced double-flute design effectively eliminates chatter and reduces vibration.
  • Secure Grip: Three-flat shank design ensures a tight hold in the chuck and prevents slippage.
  • Long Life: Cutting edges are re-sharpenable to extend the usable life of the tool.
  • Multi-Material Use: Ideal for drilling sheet metal, PVC, wood, veneers, plasterboard, and various metals.

  • (1) SDH6 Bit (6 steps, 3/16 in. to 1/2 in.)

Pro-Tip: Step bits generate significant friction, which is the primary cause of dulling. When drilling through metals like steel or stainless steel, always use a cutting lubricant or oil and run your drill at a lower RPM. This keeps the bit cool, preserves the cutting edge, and ensures a cleaner hole.
