Asahi Drilltec and Kalex Bits and Shoes are designed for soft formation drilling and are available in all standard sizes.

We also manufacture Drilltec Pilot Bits for inseam drilling in coal mines. The design incorporates a 16mm metric thread in the front of the Bit to cater for a Pilot Bit and features large irregular particles and waterways with large water holes.

Standard Pilot Bit sizes are 65mm and 80mm with AW / AWJ rod box thread. Other sizes and threads can be manufactured to order.

To further increase the hole diameter a Drilltec Hole Opener can be used behind the Bit. These Bits used with hole openers can be utilised with low torque drilling.

The combination of a 65mm Pilot Bit and an 80mm hole opener has proved successful when attempting to stay in the seam as it generally will deflect off the roof and floor.

Many of our mining products can be re-tipped, refurbished and repaired at our Sydney factory. Click here for more information.
