Special steel in combination with the production according to DIN 338, provides a high breaking resistance.
Cobalt alloy makes the drill bit highly heat-resistant and suitable for tough and hard materials.
Split point for optimum centering and reduced feed force effort.
135° tip angle for quick drilling progress.
Type N spiral for optimum chip removal.
Spiral drill bit made of robust HSS-Co steel and in accordance with DIN 338, precision ground. The split point with 135° ensures quick drilling progress. Thanks to the cobalt alloy, it is highly suitable for processing tough and hard materials.
