Ground drill with aggressive blade geometry. Thanks to the titanium nitride coating, it dissipates heat very efficiently and does not dull when working in hard steel grades. The 135 ° blade rake angle enables drilling even without first using a center punch. Made according to DIN 338 for professional use in industry.
Drill with cylindrical shank intended for standard self-locking and key chucks. High pressure resistance also allows use with column and magnetic drills.
Purpose / Application
Drilling in high-grade steel, including stainless, structural and cold-rolled.
Drilling without scoring due to aggressive blade geometry. Fast heat dissipation allows you to work without the use of a coolant, without burning the drill.
