Promac HA20.0x250 - 20 x 250mm Hardwood Auger Drill Bit

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.

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.
