Featuring a unique tapered design, this auger is built to reduce friction and improve the efficiency of the cutting head in the most challenging sub-surface environments. Equipped with heavy-duty tungsten rotating rock picks, it provides the concentrated ripping power required to penetrate solid rock, including bluestone, basalt, sandstone, mudstone, and concrete.\u003c\/p\u003e\n\u003cp data-path-to-node=\"4\"\u003eThe tapered flighting design is the key to the TR4’s success, allowing for aggressive cutting while ensuring the auger can be easily extracted from deep bores in heavy material. Built with reinforced 8mm thick flights and a high-grade steel centre tube, this model is designed to deliver high penetration rates in non-fracturable materials where standard augers fail. The TR4 ensures that maximum downward pressure is focused directly on the tungsten carbide tips, allowing for a precise grinding action that clears a clean path through the toughest terrain.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"5\"\u003e\u003cb data-path-to-node=\"5\" data-index-in-node=\"0\"\u003eKey Product Features\u003c\/b\u003e\u003c\/h3\u003e\n\u003cul data-path-to-node=\"6\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,0,0\"\u003e\u003cb data-path-to-node=\"6,0,0\" data-index-in-node=\"0\"\u003eAustralian Made:\u003c\/b\u003e Designed and manufactured locally to withstand the extreme demands of drilling into solid Australian rock and concrete.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,1,0\"\u003e\u003cb data-path-to-node=\"6,1,0\" data-index-in-node=\"0\"\u003eTapered Design:\u003c\/b\u003e Engineered to reduce drag and friction, allowing for smoother drilling and easier extraction in dense rock.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,2,0\"\u003e\u003cb data-path-to-node=\"6,2,0\" data-index-in-node=\"0\"\u003eRotating Rock Pick Pilot:\u003c\/b\u003e Features a heavy-duty pilot specifically designed to lead the auger into hard surfaces, ensuring stability and preventing wandering.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,3,0\"\u003e\u003cb data-path-to-node=\"6,3,0\" data-index-in-node=\"0\"\u003eRotating Rock Pick Teeth:\u003c\/b\u003e Equipped with high-grade tungsten carbide rotating rock picks that provide a continuous grinding action for solid rock.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,4,0\"\u003e\u003cb data-path-to-node=\"6,4,0\" data-index-in-node=\"0\"\u003eVersatile Drive Hubs:\u003c\/b\u003e Available in 65mm Round, 50.8mm Hex, and 57mm Square drive sizes to suit your specific drive unit.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,5,0\"\u003e\u003cb data-path-to-node=\"6,5,0\" data-index-in-node=\"0\"\u003eTrue Cut Technology:\u003c\/b\u003e Guaranteed to deliver the specified hole diameter throughout the entire depth of the bore.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,6,0\"\u003e\u003cb data-path-to-node=\"6,6,0\" data-index-in-node=\"0\"\u003eHeavy-Duty Construction:\u003c\/b\u003e Built with a reinforced centre shaft and thick steel flights to handle the extreme torque required for rock drilling.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,7,0\"\u003e\u003cb data-path-to-node=\"6,7,0\" data-index-in-node=\"0\"\u003eCompatible with Auger Torque S4 Drives:\u003c\/b\u003e TR4 65mm Round Drive Augers will fit Auger Torque S4 Drives.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-path-to-node=\"7\"\u003e\u003cb data-path-to-node=\"7\" data-index-in-node=\"0\"\u003eFrequently Asked Questions\u003c\/b\u003e\u003c\/h3\u003e\n\u003cp data-path-to-node=\"8\"\u003e\u003cb data-path-to-node=\"8\" data-index-in-node=\"0\"\u003eWhen should I choose the TR4 over the DR4 series?\u003c\/b\u003e The TR4 is specifically chosen when additional clearance or reduced friction is required in heavy rock drilling.
