RUKO βυθιζόμενο τρυπάνι DIN 373 HSS-E M10 κώνος Morse 2

Creating a precise, clean countersink for M10 cylindrical head screws in tough materials can be challenging with standard bits. This RUKO countersink solves that problem by providing a ground, high-performance tool that produces accurate 90° chamfers in steel, cast iron, and non-ferrous metals.

Who is it for

Machinists, metalworkers, and maintenance professionals who need a reliable countersink for socket head cap screws or similar fasteners in materials up to 1000 N/mm². Ideal for both manual and machine applications where a Morse Taper 2 shank is used.

Main features

• Manufactured to DIN 373 for consistent geometry and performance.
• Made from HSS-E (cobalt high speed steel) for enhanced heat and wear resistance.
• Three flutes provide smooth cutting and efficient chip evacuation.
• 90° cutting angle suits standard cylindrical head screws.
• Morse Taper 2 shank ensures secure mounting and concentricity.
• Bright finish reduces friction and improves chip flow.
