RUKO KEB-HM-Weldon-36.0mm Solid Carbide Core Drill, 36 mm Cutting Diameter, 30 mm Cutting Depth, Weldon Shank 19.05 mm

Core drilling in tough materials like steel up to 1400 N/mm², stainless steel, and cast iron demands a tool that stays sharp, cuts clean, and lasts. The RUKO KEB-HM-Weldon-36.0mm solid carbide core drill answers that need with a precision-ground 36 mm cutting diameter and a 30 mm cutting depth, producing burr-free holes with high accuracy.

Who is it for

This annular cutter is built for machinists, fabricators, and maintenance professionals who use magnetic drilling machines or drill presses with Weldon holders. It suits workshops that regularly drill large-diameter holes in metals and need consistent, high-quality results without frequent tool changes.

Main features

• Solid carbide (hard metal) construction for extended tool life and high performance.
• Dura-Tec multi-layer coating reduces friction and heat, improving wear resistance.
• Weldon shank with 19.05 mm (3/4") diameter for secure, concentric mounting.
• Optimized 4-flute geometry ensures efficient chip evacuation and lower cutting forces.
• Compatible with internal and external cooling systems to manage heat during cutting.
• Precision ground for tight tolerances and clean, burr-free hole finishes.
