Router Cutting Tips for Aluminium: Getting the Best Results

Mastering Aluminium Routing with the Right Tools
Routing aluminium needs precision, the right technique, and bits designed for metal cutting. Atlas Tools aluminium router bits are engineered for clean cuts, extended tool life, and consistent results.
Why bit quality matters
Not all router bits are created equal — aluminium punishes poor geometry and rough flute finishes. Our aluminium bits include features that reduce heat, prevent chip welding, and improve finish quality.
1
Polished flutes
Smooth flutes reduce chip buildup and improve evacuation — cleaner cuts with less heat.2
Passivation treatment
Enhanced surface treatment increases corrosion resistance and durability — longer bit life.3
DLC coating option
Diamond-Like Carbon coating adds hardness and reduces friction — significantly longer tool life.Essential cutting tips
1
Speed and feed rates
Use higher spindle speeds (18,000–24,000 RPM) with moderate, steady feed rates. Too slow = heat. Too fast = deflection and edge damage.
2
Lubrication is key
Always use a suitable cutting lubricant or coolant. It prevents chip welding, reduces heat, and extends tool life — even with DLC-coated bits.
3
Chip evacuation
Polished flutes help, but you still need to clear chips. Use compressed air or vacuum extraction to avoid re-cutting and heat buildup.
4
Climb vs. conventional cutting
Climb cutting often produces better edges and less burr on aluminium, but only do it if your CNC/router has minimal backlash and solid rigidity.
5
Depth of cut
Take multiple shallow passes instead of one deep cut. For most work, 1–3mm per pass is a solid starting point to reduce heat and tool stress.
6
Secure your workpiece
Aluminium can move easily. Clamp properly or use vacuum hold-down to prevent shifting, chatter, and tool damage.
Maintenance for longevity
Even with passivation treatment and DLC options, proper maintenance extends bit life and keeps finishes consistent.
Clean bits after each use with a suitable solvent to remove aluminium residue
Inspect cutting edges regularly for wear or damage
Store bits in a dry environment to prevent corrosion
Avoid dropping or striking bits against hard surfaces
