Drills offer 140% more life

A re-engineered drill range from Seco Tools is said to increase tool life by 140%. The company’s Perfomax indexable-insert drills feature a new flute design with special anti-friction surfaces and laser-hardened fronts (60 HRc) that provide added strength, stability and accuracy.

Furthermore, the flutes have larger helixes, centre chip areas and smoother chip-flute exits, while an engineered wave pattern helps minimise contact between chips and flute surfaces. The new design also features a larger radius at the bottom of the drills’ insert pockets for extra rigidity.
Ultimately, Perfomax drills generate shorter chips that can be evacuated quickly and thereby reduce the risk of chip jamming’ which, if left unchecked, can damage the workpiece and have a negative impact on process security.
Seco’s DS2050 and DS4050 insert grades, which are recommended for use with the new Perfomax drills, are suited to drilling heat-resistant materials like titanium and titanium alloys. These grades, with their recently developed free-cutting MP and MC geometries, help increase productivity and extend insert life, says the company.
Perfomax drill bodies are available in a range of diameters from 15 to 59 mm, and in length to diameter ratios of 2xD, 3xD, 4xD and 5xD. Compatibility is offered with most spindle interfaces.
