Description & Specs

The Frost 4-25mm HSS-TiN step drill bores a range of hole sizes with a single bit, stepping from 4mm up to 25mm across 11 fixed steps. The TiN coating adds wear resistance, making it a tidy solution for clean holes in sheet metal and plastic.

  • Range: 4-25mm
  • Steps: 11
  • Material: HSS-TiN (titanium nitride coated high-speed steel)
  • Shank: 1/4" hex

Designed for sheet metal and plastic, it is handy for electrical, sheet-metal and panel work, and the 1/4" hex shank fits impact drivers and quick-change adaptors.

Brilliant Aussie deal

Been buying Frost gear for years and this is one of their better ones. The Frost 4-25mm quality is excellent — everything was included and setup took under 10 minutes. Had it at the door in Brisbane within 2 days. My son immediately claimed it for himself so I had to order another. 10 out of 10.

Worth every cent

Did a lot of comparison shopping before buying here and I have no regrets. Best price I found anywhere and delivery was fast — 3 days to Melbourne. Product feels genuinely premium, not cheap at all. Packaging was solid too, box arrived in perfect shape. Will be back for more.
