HSS-E Jobber drill bit, type TLS1000

HSS-E Jobber drill bit, DIN 338, ground, tip angle 130°, type TLS1000. The TLS1000-spiral provides excellent chip-evacuation enabling deep-drilling operations (>5xD without pecking is possible). Special web thinning (DIN 1412-S) (DIN 1412-C < ø3,0) for optimized chip breaking, reduced axial load and lower torque. Very stable drill bit with excellent heat resistance.

Very suitable for drilling non-alloyed and alloyed steels (tool steels, stainless steels etc.) as well as long chipping materials with tensile strengths up to 1.300N/mm².
Material groups : 1.1 - 1.5 / 2.2 - 2.3 / 3.1 - 3.3 / 4.2 - 4.5 / 4.7 / 4.11 - 4.12 / 5.1 - 5.4
