longyear™ diamond bits - boart longyear

the longyear bits are similar to large diamond bits but with the easy smooth drilling characteristics drillers prefer. this means increased productivity throughout the entire operation and ultimately more core. to support higher penetration rates the new longyear™ formulas are combined with a new more open express geometry.the right tool for everyone!the pdc 1 drilling assistant (optional accessory) offers you practical advantages such as dust extrac-tion screw holder drill centring and depth control: 1. more than 80% of the dust is extracted during drilling. 2. quick and easy adjustment of the drilling depth. 3. the large dust box is easy to empty and clean. pdc 1 drilling assistant
