The Steep Taper Ultra Bit 3 performs in hard, compact soil and gravel conditions. A 4-inch and a 5-inch model are available. For ground where it is hard to do directional “pushes”, the Steep Taper Ultra Bit 3’s conical carbide cutters set at an aggressive angle to get through cobbles. A center point tooth provides easier penetration. A chunky carbide hardfacing the entire length of blade gives maximum longevity to the bit. The Steep Taper offers a low-profile, tapered design to minimize torque stealing drag. 800.558.7500, www.melfredborzall.com
