With varying applications and soil types in mind, Lone Star Drills has made four drill bit options available with different capabilities.

The heavy-duty bits are designed for water well, geotechnical and geothermal drilling.

For clay, sand and medium hard formations, Lone Star offers step drag bits. “The hardness of the bits makes them last long and retain a sharp cutting edge,” says Joe Haynes, president of Little Beaver, which manufactures Lone Star Drills. The pilot bits are three-wing, three-step for drilling holes quickly. They come in four sizes and feature carbide mounted on a 5/8-inch steel plate for durability and easy sharpening.

Roller cone bits, or tricones, are ideal for tough soils and rock thanks to their long-lasting tungsten carbide inserts. Three wheels studded with carbide spin as the bit turns. Lone Star offers the more economical roller cone bit option in two sizes.

Clean, precise round holes are achieved by PDC bits, fit for drilling in medium rock formations like granite and sandstone. They utilize balanced polycrystalline diamond compact cutters that reduce bit whirl. The bits cut through the rock using a scraping method as the cutter turns. This helps achieve maximum penetration rates by minimizing plugging. Lone Star offers the PDC drill bits in two sizes.

Finally, for the toughest of clay formations, Lone Star has designed claw bits. By ripping while digging in and loosening soil, their three fingers reduce over-torqueing and stalling. The replaceable fingers are made to last and the bits come in two sizes.

Lone Star Drills touts its products as a “convenient and powerful solution in areas with minimal resources for transportation and operation.” The company is a division of Little Beaver, which designs and manufactures hole-digging equipment in Livingston, Texas.
