671 General DIG-R-TACH TCT Series Earth Augers

The TCT Series Earth Augers from the 671 General DIG-R-TACH lineup are the extreme-duty champions of the auger world, purpose-built for when standard tools just can’t cut it. Designed to rip into highly compacted soils and fracturable rock, these augers turn difficult ground into manageable material when paired with high-torque drive units and heavy equipment. Whether mounted to skid loaders, tractor-loader backhoes, excavators, or track-type carriers, the TCT Series unleashes brute force that keeps productivity moving when conditions try to bring you to a halt. Rugged, aggressive, and engineered for battle, this is serious hole-digging power you can depend on.

FEATURES

• 2.0 INCH HEXAGON AUGER DRIVE CONNECTION: Provides a secure, high-strength interface for maximum torque transfer. Designed for heavy-duty powerheads delivering the force needed in extreme digging conditions.
• ONE PIECE, CAST STEEL BORING HEAD: Positions the teeth for maximum ground engagement and long-lasting wear performance. Delivers precise cutting in the most punishing environments.
• FIELD REPLACEABLE CAST STEEL PILOT HEAD: Reduces downtime and maintenance costs with simple on-site replacement. Keeps your operation moving without needing full auger rebuilds.
• FIELD REPLACEABLE TUNGSTEN CARBIDE CONICAL (BULLET)-TYPE TEETH: Built for maximum wear resistance and convenience. Quickly swap out teeth in the field to match soil and rock conditions, or to refresh performance without delay.
• HEAVY-WALLED AXLE: Designed to handle extreme torque and bending forces. Keeps the auger steady and aligned through dense, rocky, or compacted terrain.
• HEAVY-GAUGED, STEEL, HELICOID SECTIONAL FLIGHTING: Reinforced flighting provides maximum structural integrity under repeated impact. Moves material efficiently and resists wear in harsh jobsite conditions.
