RUKO KEB-HSS-TiAlN-Mod.55-40.0mm Annular Cutter (Core Drill), 40 mm Cutting Diameter, 55 mm Cutting Depth, TiAlN Coated HSS, 19 mm Weldon Shank

Annular cutter (core drill) with 40.0 mm cutting diameter and 55 mm cutting depth, made from high-speed steel (HSS) with a titanium aluminum nitride (TiAlN) coating for high wear resistance and extended tool life. The 19 mm Weldon shank (3/4") ensures secure clamping in magnetic drilling machines and pillar drills with adapter. Internal coolant channels deliver coolant directly to the cutting zone, enabling higher cutting speeds and improved heat resistance.

Advantages

The TiAlN coating provides increased hardness and improved heat resistance compared to uncoated HSS, allowing higher cutting speeds and extended tool life. Precision ground manufacturing ensures accurate hole dimensions and clean cutting edges. Internal coolant channels optimize cooling and chip evacuation, reducing tool wear and improving surface finish.

Suitable for

• Steel
• Stainless steel
• Cast iron
• Non-ferrous metals

Key specifications
