Drilling tools

Design: Ultra-finest grain-solid carbide, factory standard, type RT 100 T. TiAlN coated surface, right cutting. Special slot form with double bevels, special point geometry and special point thinning. With inner cooling. Normal angle of rake 30°, core thickness thicker than normal and without core gradient. The drill has a very good self-centring behaviour. Application: For drill holes with very narrow ∅ tolerances and very good surfaces. Suitable for drilling extremely deep holes up to 20 x D with high cutting speeds. Particularly suitable for short-chipping materials such as cast iron, grey cast iron, malleable cast iron and nodular graphite iron and aluminium alloys with a high silicon content. Note: The drills can be sharpened several times. RT 100 T method: • Mill a surface at right angle to the start angle of hole machining. • Produce a cylindrical pilot hole (tolerance F9) with a drilling depth of at least 1 x D. • Insert into the pilot hole with approx. 300 rpm at f = 500 mm/min. • Set the cooling lubricant pressure and speed. • Continual drilling to full drilling depth without relief cycle. • When drilling through holes with oblique exit, reduce the feed rate v f to 40% ca. 1 mm before breaking through. Deep hole drill, 20 x D

• After reaching the drilling depth, switch off the rotation and coolant, extract in rapid traverse. • Conventional coolant lubrication min. 40 bar

Note: The drills can be sharpened several times.

Cutting Tools 1

All deep holes must be piloted before starting to drill. Deep hole drills should never be moved freely in the machine when at the full speed.
