Mills Machine offers Milclaw and Kenclaw rotary drilling bits for the Water Well, Blast Hole Mining, Construction and Shallow Oil Drilling Industries. Strong KenClaw body is inside the gage cut to allow for fluid passage. Stronger/ toughter MilClaw body extends out to the gage cut and has triangular cuts to allow fluid flow. This gives faster penetration rate and allows drilling in rock up to 10,000 psi.
Mills Machine stocks a wide variety and size of rock bit (also known as roller cones or roller bits). We use this bits to meet your immediate needs and as inventory to build hole openers and underreamers. The bits we use are either new or reworked. The reworked bits are known as "retip" for the Steel Tooth Bit and "rerun" for the TCI Button Bit. Rework bits give at least 50% of the life of a new bit.
