RUKO KEB-HSS-TiAlN broca de corona 54 mm mango Weldon

For metalworkers and maintenance crews using magnetic drilling machines, the RUKO KEB-HSS-TiAlN core drill bit cuts clean 54 mm holes in steel, stainless steel, cast iron, and non-ferrous metals. Its TiAlN coating withstands high heat, extending tool life in demanding production environments.

Key specifications

• Cutting diameter: 54.0 mm
• Material: High-speed steel (HSS)
• Coating: Titanium Aluminum Nitride (TiAlN)
• Shank type: Weldon shank, 19 mm (3/4 inch)
• Cutting depth: 30 mm
• Total length: 85 mm

Why choose it

The TiAlN coating provides high wear resistance and improved heat resistance, ensuring consistent performance and longer tool life. Precision-ground multi-tooth design delivers accurate, burr-free holes with automatic core ejection.

Ideal use cases

• Drilling large diameter holes in steel plates and structural sections
• Stainless steel fabrication where heat resistance is critical
• Maintenance and repair work on heavy machinery
• Use with magnetic drilling machines or pillar drills with appropriate arbor

Good to know

Coolant is recommended for optimal performance and extended tool life. The annular design removes only the periphery, reducing power consumption and drilling time compared to solid twist drills.
