Frequently Asked Questions

  • What is a step bit for?

    It cuts several diameters with one bit and leaves a burr-free edge in thin sheet. In panels, enclosures and light gauge metal it replaces a whole drill set; it is not for thick material.

  • What drills tile and granite?

    Diamond bits. Diamond abrades rather than cuts: hammer off, low speed, and water cooling where specified.

  • Do multi-material bits really work in everything?

    They work in tile, brick, timber and thin sheet, and their advantage is not stopping to change bits. They will not match a dedicated bit's performance in any one material.

  • How is a spot weld cutter used?

    It mills out the weld nugget without drilling through the panel beneath. Work at low speed, square to the panel; it is the standard tool for body strip-down.
