Three-Flute Drill Extends Tool Life at Higher Feed Rates
Mapal’s three-flute Tritan-Drill is said to achieve more bores, a longer tool life and lower machining costs compared with two-flute drills.
Mapal’s three-flute Tritan-Drill is said to achieve more bores, a longer tool life and lower machining costs compared with two-flute drills. This universal drill handles a range of materials and provides rounder bores with fewer burrs, the company says, thanks in part to a tool geometry optimizing chip removal and providing low cutting pressure. The drill’s design enables higher feed rates with process reliability, and includes chip formation features making it useful for long-chipping materials. Models are available with diameters ranging from 5 to 20 mm and in lengths ranging to 8×D.
Applications include machining cylinder heads at high feed rates, VA rails made of heat-resistant steel alloys, and turbochargers made of cast steel. The drill can handle steels, cast materials and nonferrous metals.
