Electricians and sheet metal workers use this step drill bit to create clean, burr-free holes in control panels and junction boxes. The TiN-coated HSS body steps from 3/16" to 1/2" in six increments, letting one tool replace a full set of twist drills for thin materials.

Key specifications

  • Drill bit type: Step drill bit
  • Material: High-speed steel (HSS) with titanium nitride (TiN) coating
  • Diameter range: 3/16" - 1/2" (4.8 mm - 12.7 mm)
  • Number of steps: 6
  • Step increments: 3/16", 1/4", 5/16", 3/8", 7/16", 1/2"
  • Shank type: Straight shank, 6 mm diameter

  • Flute type: Two-flute spiral
  • Self-centering: Yes
  • Deburring capability: Yes
  • Standard: DIN 1412 C

Why choose it

The TiN coating reduces friction and heat build-up, extending tool life when drilling stainless steel up to 2 mm thick. The two-flute design clears chips efficiently, while the 118° point starts accurately without a center punch.

Ideal use cases

  • Enlarging existing holes in sheet metal up to 4 mm thick
  • Drilling clean holes in non-ferrous metals, plastics, and thin steel
  • Deburring hole edges in one operation

Good to know

Use cutting fluid or coolant for best results. The step drill is not intended for thick plate or hardened steel.
