Promac Hardwood Augers are the ultimate solution for drilling into tough Australian hardwoods, including Ironbark. These augers are engineered to handle the demanding nature of hardwoods with precision and durability.
Key Features:
Coarse Thread Design: The coarse thread design prevents clogging, allowing the auger to penetrate hardwood much faster, even at low revs (approximately 250rpm). This feature ensures efficient drilling with less strain on your tools.
Durable Cutting Edges: Equipped with two horizontal edges at very obtuse angles on the cutting head, these augers are built to last. The durable design reduces the need for frequent sharpening, saving you time and effort.
Versatile Range:
Sizes: Available in a comprehensive range from 10mm to 32mm, catering to various drilling needs.
Lengths: Offered in overall lengths of 250mm, 450mm, and now an extended 1m in selected sizes for deeper drilling applications.
Extensions: For through drilling, extensions are available, with sizes 22mm and over recommended to accommodate the overlap of the extension.
Promac Hardwood Augers are specifically crafted for the unique challenges of Australian hardwood, ensuring that you can drill with confidence and precision. Whether you need a standard length or an extended reach, Promac offers the quality and performance you need to get the job done right.

🪓 Frequently Asked Questions
Q: What are Promac Hardwood Auger Drill Bits used for?
A: These auger bits are specially designed for drilling into tough Australian hardwoods such as Ironbark and Jarrah. Their coarse thread and durable cutting edges make them ideal for clean, fast holes without clogging.
Q: Can I use these auger bits with any drill?
A: Yes. Promac Hardwood Augers are compatible with most power drills. For best results, use a drill with a low-speed setting around 250 RPM to prevent overheating and ensure smooth cutting through dense timber. Promac Hardwood Auger Bits feature an atom (hex) shank, making them compatible with most standard power drills and drill drivers. The hex design prevents slippage and ensures a secure grip — perfect for high-torque hardwood drilling.
Q: What sizes and lengths are available?
A: The range covers sizes from 10 mm to 32 mm, with lengths of 250 mm, 450 mm, and 1 m for deep drilling applications. Extensions are also available for through-drilling jobs.
Q: Do these augers need frequent sharpening?
A: No. The cutting edges are engineered for durability, reducing wear and keeping the bit sharp for longer — even with heavy use in hardwood.
Q: Are replacement parts or extensions available?
A: Yes to extensions, no parts. Promac offers compatible auger extensions and accessories to suit different drilling depths and applications.
