RUKO KEB-HSS-TiAlN Core Drill Bit 47.0 mm, Weldon Shank 19 mm

This RUKO core drill bit stands out with its TiAlN coating, which delivers superior wear resistance and heat protection compared to uncoated HSS cutters. The 47.0 mm diameter and 30 mm cutting depth make it a dependable choice for creating large holes in steel, stainless steel, cast iron, and non-ferrous metals.

Highlights

• High-speed steel (HSS) body with Titanium Aluminum Nitride (TiAlN) coating for extended tool life
• Annular cutting design removes only the periphery, leaving a solid core for efficient chip removal
• Weldon shank 19 mm (3/4") for secure mounting in magnetic drilling machines
• Precision ground multi-flute geometry for clean, accurate holes

In daily use

The hollow core design reduces cutting forces and heat build-up, allowing faster drilling with less power consumption. Coolant is recommended to maximize performance and tool life, especially in tough materials. The cutter is suitable for industrial and professional applications where repeatable accuracy is required.
