⚡ At a Glance
- • Cutting Quality: Clean aluminium removal with smooth side walls and limited burring
- • Best for: Machinists and hobbyists working aluminium who need reliable finishing results
- • Not ideal for: Materials requiring specialised coatings or extremely hard alloys
A 3-flute square-corner end mill with DLC coating designed for aluminium work. Suitable for slotting, grooving, side milling, roughing and finishing on CNC and manual hobby mills.
Cleaner finishes - thanks to DLC coating
Diamond-like carbon coating lowers friction and improves lubricity, which reduces material adhesion on the cutting edges. Enhanced wear resistance helps at higher cutting speeds and temperatures.
Fewer built-up edges and less polishing after machining, so finishing steps are quicker and more consistent.
Faster, steadier cuts - with three-flute geometry
Three flutes provide a compromise between chip clearance and cutting-edge count, maintaining effective evacuation while offering multiple cutting passes per revolution. Geometry suits both higher feedrates and controlled finishing passes.
Slotting and grooving become more efficient without frequent clogging, improving cycle times for aluminium components.
Accurate corners - thanks to sharp square corner profile
Sharp square corners preserve internal angles and reduce radial rubbing compared with radiused profiles, maintaining dimensional accuracy. Square profile delivers predictable tool engagement in tight features.
Produces precise slots and true internal corners, reducing the need for secondary machining on fit-critical parts.
