Stepped Auger Bits - AS1085.18 (Section A3.2) suggests that Screw Spike holes should be stepped with a larger hole for the shank and a smaller hole for the threaded portion. - Stepped Augers feature both a large diameter (for the screw shank) and a smaller diameter ( for the screw thread) in the one drill.
- Stepped Augers have a collar fitted to ensure precise drilling depth and are matched to our screws.
- Durable body — forged SAE 1060 steel, austemper heat-treated and coated with anti-corrosive oil for longer life
- Self-feeding screw point — for faster boring into all types of wood
- Mathieson-type twist — for drilling in hard woods
- Hex shank — prevents bit from slipping in chuck
- Twin flute improves cutting and ensures fast chip removal.
