- Promac hard wood augers are designed specially for Australian hardwood.
- Coarse thread doesn't clog and makes for much faster penetration at low revs approximately 250 RPM.
- Two horizontal edges with very obtuse angles on cutting head, they last longer reducing sharpening and increasing amount of work between sharpens.
- Hex drive shank (atom compatible)
- Extensions are also available. For through drilling you require 22 mm and over.
- Made in Taiwan.
