PRODUCT OVERVIEW
The current evolution of the LF™ 90 long stroke is the LF™ 90D hydraulic diamond core drill. It is considered to be one of the most productive deep hole drills in its class and is packed full of new features. FEATURES: • Dump mast — creates a stable working platform and lowers the working heightdramatically. • Patented Nitro-Chuck® — offers you performance and reliability (1 year warranty). • Telescopic mast — compact transport size but still capable of 6 m (20 ft) rod pulls, easy onsite setup. • Independent dual hydraulic mast raising cylinders. • Side shifting head for improved rod handling. • Mounting configuration — truck mounted for mobility.

DRILLING DEPTH GUIDELINES
The figures in these tables have been calculated, based on field experiences, and may be reasonably expected. Ratings arebased on a vertical, straight, clean down hole using a 7 258 kg (16,000 lb) hoist (single line pull). Actual drilling capacity will depend on in-hole tools, conditions, drilling techniques and equipment used.
