What Are Spiral Drill Bit Teeth?
1.Downhole drilling machine: When drilling a downhole gun hole with a aperture less than 150 mm, in addition to the application of a rock drill, it can also be used to drill a small diameter of 80 ~ 150 mm. When drilling a gun hole with a diameter of less than 70 mm in coal or softer mineral rock, it is generally used to drill or air drill, driven by a motor (or air motor) to drill the drill pipe, and the rock (coal) chips drilled out are discharged through the spiral groove on the drill pipe.
1. Enhanced Performance The design of spiral drill bit teeth allows for better penetration rates compared to standard drill bits. This increased performance results in shorter drilling times and higher productivity.
