PFERD TOOLS PFERD 25201048 - HSS step drills, 3.5-40/10

HSS step drills for drilling and deburring thin sheets, pipes and profiles made from various materials. All step drills are equipped with a three-surface shaft for secure torque transmission. Tailored to the most common cable gland diameters. Technical data: Number of drill steps: 15 RPM of hard non-ferrous metals: 160 rpm RPM of rust and acid-resistant steels: 160 rpm RPM of soft non-ferrous metals: 80 rpm RPM of steels up to 700 N/mm²: 160 rpm RPM of thermoplastics, fibre-reinforced plastics (GRP/CFRP): 80 rpm RPM up to, for hard non-ferrous metals: 2700 rpm RPM up to for rust and acid-resistant steels: 1850 rpm RPM up to, for soft non-ferrous metals: 2700 rpm RPM up to, for steels up to 700 N/mm²: 2700 rpm RPM up to, for thermo- plastics, fibre-reinforced plastics (CRP/GRFP): 1850 rpm Version: HSS Drill steps: 3.5/6.3/10.5/12.5/15.3/18.7/20.5/22.6/26.0/28.3/29.1/32.0/35.6/37.5/40.0 Shaft diameter, metric: 10 mm Drilling range, from: 3.5 mm Drilling range, up to: 40 mm Length, total: 120 mm Advantages: Drilling and deburring in a single step. Incredibly smooth running and excellent cutting performance. Effortless to centre and drilling thanks to the high-quality drill tip. Easy to pull back when working on perforated sheets thanks to the tool cone. Non-breaking chips are cleanly transported away with a spiral drill bit.
