Why choose it

The TiAlN coating reduces friction and heat, allowing faster cutting speeds and longer intervals between regrinds. Optimized chip evacuation keeps the cutting zone clear, improving hole quality and tool life.

Ideal use cases

• Core drilling large diameter holes in steel plates and profiles
• Creating holes for pipework, cable glands, and structural connections
• Use on magnetic drilling machines in fabrication shops and on-site

Good to know

The Weldon shank ensures secure clamping and accurate centering in standard drill chucks and arbors. Internal cooling capability allows efficient heat dissipation when used with appropriate coolant supply.
