RUKO KEB-HSS-TiAlN kernboor 46 mm

Large-diameter holes in steel and stainless steel are slow and laborious with twist drills, but this RUKO annular cutter removes only a ring of material, making 46 mm holes fast and clean.

Who is it for

Professional metalworkers, fabricators, and maintenance teams using magnetic drilling machines or pillar drills who need precise, burr-free holes in steel, stainless steel, cast iron, and non-ferrous metals up to 900 N/mm² tensile strength.

Main features

• High-speed steel (HSS) body with TiAlN coating for high heat resistance up to 900°C and excellent wear resistance.
• Multi-cut geometry for smooth, fast drilling — up to 3x faster than conventional twist drills for large holes.
• Weldon shank with 19.05 mm (3/4 inch) diameter for secure mounting in magnetic drilling machines.
• Designed for internal cooling to maintain cutting performance.
• Cutting depth: 30 mm; cutting diameter: 46 mm.
