HFP Heavy Duty Dedicated Rock Auger Bit | 300mm to 1500mm | 110mm Square Hub | From $3,490 inc GST
Heavy Duty Dedicated Rock Auger Bits Built for Hard Rock and High Torque Drilling Applications
The HFP Heavy Duty Dedicated Rock Auger Bit range is engineered for contractors, civil works, utilities, infrastructure projects, local government, mining support, quarry operations, solar farms, hire companies, OEMs, and major earthmoving operations requiring maximum drilling performance in hard and abrasive ground conditions.
Designed to suit high torque auger drives running a 110mm square hub, this premium auger range is built specifically for demanding rock drilling applications where standard earth augers or multifaceted tungsten augers are not suitable.
Fitted with large rotating rock picks and a heavy-duty rock pilot, the HFP 110mm Dedicated Rock range is designed to penetrate shale, fractured rock, decomposed rock, weathered rock, hard ground, and abrasive drilling conditions while maintaining strength, durability, and efficient spoil removal.
The 110mm square hub design, 2300mm overall length, heavy-duty tube construction, reinforced flighting, and aggressive rock cutting system make this range ideal for larger machines, high torque drives, and commercial drilling environments where downtime is costly.
Available in sizes from 300mm through to 1500mm diameter.
Supplied complete with large rotating rock picks, heavy-duty rock pilot, pin, and clip.
Built for Australian conditions and backed locally by HFP Attachments with parts, technical support, and after-sales service.
