Characteristics and usage

Non-coring bits with PDC cutters and a steel body are designed for rotary drilling of technical bore holes in soft to medium hard rock formations.

These tools are intended for applications like roof bolt drilling, blasting works, anchoring, injecting, degassing, or other during mining, geothermal drilling and other industries.

PDC non-coring bits are set with polycrystalline diamond compact (PDC) cutters of various shapes & size, depending on the type and usage of the bit.

Steel body non-coring are suitable for environments, where abrasion of the bit´s body does not pose such a threat. Therefore, they are an economic alternative to our non-coring PDC bits with matrix bodies. Another advantage of steel-bodied non-coring PDC bits is their higher ductility and consequentially higher resistance to impact loading.

Depending on the bit´s application, it´s calibration gauge is set with quality PDC segments, or tungsten carbide (TC) segments to increase wear resistance.

Main advantages of steel non-coring PDC bits

  • Very good value for money; highly effective in low-cost drilling environments
  • Option to renovate worn down bits – up to diameter of 250 mm / 9,84 inch (more info below)
