Engineered specifically for high-torque machines in the 12 to 24-tonne range, this auger is designed to conquer solid, non-fracturable rock, including high-grade concrete, granite, and basalt. Unlike standard augers that may bounce or stall, the TR11 features a distinctive tapered design that focuses maximum downward pressure onto a concentrated cutting path, allowing the high-grade rotating rock picks to \"eat\" through solid stone with surgical precision.\u003c\/p\u003e\n\u003cp data-path-to-node=\"4\"\u003eManufactured in Australia to withstand the absolute extremes of the construction and mining industries, the TR11 is built around a massive reinforced centre tube and a heavy-duty 100mm square drive hub. The tapered flighting is a masterstroke of engineering; it minimises friction while ensuring that crushed rock spoil is efficiently lifted away from the cutting face. When your project demands a hole in ground that most would consider \"undrillable\", the TR11 Tapered Rock Auger provides the mechanical advantage required to maintain your schedule and protect your drive unit from unnecessary stress.\u003c\/p\u003e\n\u003cp data-path-to-node=\"5\"\u003e\u003cb data-path-to-node=\"5\" data-index-in-node=\"0\"\u003eCompatible with Digga and Auger Torque 100mm Square Drive Hubs\u003c\/b\u003e\u003c\/p\u003e\n\u003chr data-path-to-node=\"6\"\u003e\n\u003ch3 data-path-to-node=\"7\"\u003e\u003cb data-path-to-node=\"7\" data-index-in-node=\"0\"\u003eKey Product Features\u003c\/b\u003e\u003c\/h3\u003e\n\u003cul data-path-to-node=\"8\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"8,0,0\"\u003e\u003cb data-path-to-node=\"8,0,0\" data-index-in-node=\"0\"\u003eRotating Rock Picks:\u003c\/b\u003e Equipped with heavy-duty, rotating tungsten carbide rock picks that self-sharpen during operation for consistent cutting performance.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"8,1,0\"\u003e\u003cb data-path-to-node=\"8,1,0\" data-index-in-node=\"0\"\u003eTapered Engineering:\u003c\/b\u003e The specialised tapered flighting reduces peripheral drag and focuses the machine’s crowd pressure directly onto the rock face.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"8,2,0\"\u003e\u003cb data-path-to-node=\"8,2,0\" data-index-in-node=\"0\"\u003e100mm Square Drive:\u003c\/b\u003e Features a reinforced hub specifically designed to handle the extreme torque outputs (15,000Nm to 42,000Nm) of large excavators.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"8,3,0\"\u003e\u003cb data-path-to-node=\"8,3,0\" data-index-in-node=\"0\"\u003eSuperior Spoil Removal:\u003c\/b\u003e Despite its aggressive rock-cutting focus, the flighting pitch is optimised to clear heavy debris and prevent \"plugging\" in the hole.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"8,4,0\"\u003e\u003cb data-path-to-node=\"8,4,0\" data-index-in-node=\"0\"\u003eExtreme Durability:\u003c\/b\u003e Constructed from high-tensile steel with heavy-duty wear strips to ensure a long service life in highly abrasive environments.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"8,5,0\"\u003e\u003cb data-path-to-node=\"8,5,0\" data-index-in-node=\"0\"\u003ePrecision Pilot Bit:\u003c\/b\u003e Features a robust rock pilot that provides a stable anchor point, preventing the auger from \"walking\" on solid stone surfaces.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-path-to-node=\"9\"\u003e\n\u003ch3 data-path-to-node=\"10\"\u003e\u003cb data-path-to-node=\"10\" data-index-in-node=\"0\"\u003eSpecifications \u0026amp; Sizes\u003c\/b\u003e\u003c\/h3\u003e\n\u003cul data-path-to-node=\"11\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"11,0,0\"\u003e\u003cb data-path-to-node=\"11,0,0\" data-index-in-node=\"0\"\u003eModel:\u003c\/b\u003e TR11 (Tapered Rock)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"11,1,0\"\u003e\u003cb data-path-to-node=\"11,1,0\" data-index-in-node=\"0\"\u003eSuits:\u003c\/b\u003e 12t – 24t Excavators\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"11,2,0\"\u003e\u003cb data-path-to-node=\"11,2,0\" data-index-in-node=\"0\"\u003eDrive Hub:\u003c\/b\u003e 100mm Square\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"11,3,0\"\u003e\u003cb data-path-to-node=\"11,3,0\" data-index-in-node=\"0\"\u003eOverall Length:\u003c\/b\u003e 1500mm\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"11,4,0\"\u003e\u003cb data-path-to-node=\"11,4,0\" data-index-in-node=\"0\"\u003eCutting Teeth:\u003c\/b\u003e Rotating Tungsten Carbide Picks\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"11,5,0\"\u003e\u003cb data-path-to-node=\"11,5,0\" data-index-in-node=\"0\"\u003eFlighting:\u003c\/b\u003e Tapered Heavy-Duty Steel\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-path-to-node=\"12\"\u003e\n\u003ch3 data-path-to-node=\"13\"\u003e\u003cb data-path-to-node=\"13\" data-index-in-node=\"0\"\u003eFrequently Asked Questions\u003c\/b\u003e\u003c\/h3\u003e\n\u003cp data-path-to-node=\"14\"\u003e\u003cb data-path-to-node=\"14\" data-index-in-node=\"0\"\u003eWhat ground conditions is the TR11 specifically designed for?\u003c\/b\u003e The TR11 is a dedicated rock tool. It is designed for solid, non-fracturable rock such as sandstone, limestone, granite, and reinforced concrete. If you are drilling in earth or shale, the RC11 or A11 series may be more efficient, but for solid stone, the TR11 is essential.\u003c\/p\u003e\n\u003cp data-path-to-node=\"15\"\u003e\u003cb data-path-to-node=\"15\" data-index-in-node=\"0\"\u003eWhy is the auger tapered instead of straight?\u003c\/b\u003e The taper allows the auger to start a smaller \"pilot\" path which is then gradually widened. This concentrated force requires less torque to break the rock's surface compared to a flat-bottomed auger, significantly increasing your drilling speed in hard materials.\u003c\/p\u003e\n\u003cp data-path-to-node=\"16\"\u003e\u003cb data-path-to-node=\"16\" data-index-in-node=\"0\"\u003eHow do the rotating picks work?\u003c\/b\u003e The teeth are designed to rotate in their holders as they strike the rock. This rotation ensures even wear across the tungsten tip, effectively \"self-sharpening\" the tool and preventing flat spots that would otherwise reduce cutting efficiency.\u003c\/p\u003e\n\u003cp data-path-to-node=\"17\"\u003e\u003cb data-path-to-node=\"17\" data-index-in-node=\"0\"\u003eCan I replace the teeth on-site?\u003c\/b\u003e Yes. The rock picks are held in by heavy-duty circlips or retainers and can be changed quickly in the field with a Rotating Rock Pick Removal Tool (C123), also available from Earthmoving Warehouse. Regularly checking and replacing worn picks is the best way to minimise downtime and protect the auger body.\u003c\/p\u003e\n\u003chr data-path-to-node=\"18\"\u003e\n\u003ch3 data-path-to-node=\"19\"\u003e\u003cb data-path-to-node=\"19\" data-index-in-node=\"0\"\u003eWhy Choose the TR11 Series?\u003c\/b\u003e\u003c\/h3\u003e\n\u003cp data-path-to-node=\"20\"\u003eWhen the ground turns to solid stone, the TR11 is the only tool that ensures you keep moving forward. It transforms your large excavator into a high-production drilling rig, delivering the precision and power needed for foundation piers, bridge abutments, and heavy infrastructure projects. By choosing the TR11, you are investing in an Australian-built powerhouse that prioritises durability and performance, ensuring that no ground is ever truly off-limits.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cstrong\u003ePROUDLY PRODUCED AND MANUFACTURED IN AUSTRALIA\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003ePlease note that all TR augers are made to order.
