Key Features & Benefits
- TiN (Titanium Nitride) Coating — increases surface hardness to 85 HRC and reduces friction by 30%, delivering longer tool life and faster cutting speeds.
- M2AL High-Speed Steel — premium European steel hardened up to 67.5 HRC for consistent performance in demanding applications.
- Step Hardened Process — produces extremely hard tooth tips that maintain their cutting edge through heavy-duty use.
- Multi-Cut Geometry — engineered tooth profile delivers smooth, fast cutting with decreased chatter and vibration.
- Fully Ground with Internal Relief — produces reamed-quality, burr-free holes while requiring less torque from the machine.
- Multi-Fit 3/4″ Universal Shank — two flat sections on the 19.05mm shank ensure compatibility with most magnetic base drill brands.
When to Use This Cutter
The AT3025 is a 30mm diameter, 25mm depth annular cutter designed for use in magnetic base drilling machines. Choose this cutter when you need clean, accurate 30mm holes in steel plate, structural sections, or fabrication work. The 25mm cutting depth suits standard plate and section work up to 25mm thick. Requires pilot pin SP16003 (6.34mm x 77mm).
Pro Tip: Always use cutting fluid and the correct pilot pin (SP16003 (6.34mm x 77mm)) for best results. Let the cutter do the work — moderate feed pressure produces cleaner holes and extends cutter life. The TiN coating performs best at recommended speeds; avoid excessive RPM.
