Router Bits for Aluminium
Router Bits for Aluminium — Up Spiral CNC Router Bits by Atlas Tools (Australia)
Aluminium routing is all about chip evacuation, low friction, and keeping heat under control. Atlas Tools Aluminium Up Spiral router bits are tuned for clean cutting and reliable evacuation in aluminium and other non-ferrous metals.
Best sellers: 6×15 Up Spiral (Standard) vs 6×15 Up Spiral (DLC Coated). Same geometry; coating option targets lower friction + longer consistency.
ALUMINIUM UP SPIRAL
Non-ferrous machining focus: evacuation + low friction
Tip: Aluminium loves chip clearance. If you’re welding chips to the cutter, you’re either too hot, too gummy, or not evacuating cleanly.
Why an aluminium up-spiral is the default “do it properly” choice
Chip evacuation & surface finish
Aluminium makes sticky chips. Up-spiral geometry actively lifts chips out of the cut so you don’t recut debris and scratch the edge.

Heat control
Evacuation reduces rubbing. Less rubbing means less heat, less built-up edge, and less cutter loading.

DLC option = longer consistency
DLC is aimed at lowering friction and extending the window where the tool stays “sharp-feeling” on production runs.

Rule of thumb: Keep chips moving (no rubbing) If chips weld: reduce heat + improve evacuation
Aluminium Up Spiral 6×15 — DLC Coating (Best Seller)
Same cutter geometry as the standard version, but built for lower friction and longer consistency on repeat work.

Aluminium Up Spiral 6×15 — Standard (Best Seller)
Your go-to aluminium cutter when you want solid performance and value. Same core geometry; coating is the main differentiator vs DLC.

Materials these bits are suited for
Aluminium
Optimised for non-ferrous chip evacuation and cleaner edge quality.
Copper
Similar non-ferrous behaviour; focus on heat + chip control.
Brass
Stable machining when chips clear. Keep the cut clean and controlled.
Note: exact suitability depends on thickness, machine rigidity, workholding, lubrication/air blast, and your feed strategy.
Which one should you pick?
- Go DLC if you want longer “stable performance” on repeat production, or you’re pushing harder where friction becomes the enemy.
- Go Standard if you want best value and you’re not chasing maximum lifespan per cutter.
- If you’re unsure, tell us your machine, thickness, and whether you’re using air blast/coolant and we’ll point you to the right option.
Aluminium router bit FAQs
What’s the main difference between DLC and standard?
DLC is aimed at reducing friction and extending usable consistency (longevity). Geometry is the same between these two 6×15 best sellers.
What materials can I cut with these?
Primary is aluminium. They’re also suited to non-ferrous metals like copper and brass, depending on setup and chip control.
What causes aluminium to “weld” onto the cutter?
Usually heat + rubbing + poor evacuation. Improve chip clearance (air blast), keep feed moving, and reduce rubbing passes.
