Double-fluted drill

High feed rates for short-chipping materials

Two-lip drilling – a related method of deep drilling – is used in the diameter range from 6 to 25 mm and with L/D ratios up to max. 40 mm. The tools are double-edged and usually have two guide pads in addition to the two circular grinding chamfers.

These tools are made either entirely of carbide or with a carbide drill head in combination with a tubular steel shank or solid steel shank. Due to the smaller chip space, these tools are ideal for short-chipping materials.

The special extra

of our double-fluted drills are the high, realizable feed rates for short-chipping materials that they have over conventional single-fluted drills.
