Solid carbide end mills hold their cutting edge at higher speeds and temperatures than HSS, which is why they're the standard choice once you move beyond aluminium and plastics into steel, stainless and hardened material.

Flute count is the first thing to get right: 2 or 3 flutes with polished flutes clear chips fast and suit aluminium and other soft, gummy materials, while 4 or more flutes suit steel and stainless, where chip load per tooth is lower and heat resistance matters more than clearance.

Coating matters as much as flute geometry. TiAlN and AlTiN coatings handle the heat generated machining hardened and alloy steels; DLC (diamond-like carbon) coatings reduce built-up edge when cutting aluminium and other non-ferrous metals.

All eight profiles above are held in UK stock, same-day dispatch before 4pm.

Carbide end mills are harder and more heat-resistant than High-Speed Steel (HSS), allowing them to run at higher speeds and hold an edge longer. HSS tools cost less upfront, but carbide is the better choice for production runs and harder materials.

For aluminium, use an end mill with fewer flutes (2 or 3) and polished flutes. Fewer, polished flutes evacuate chips faster and stop material sticking to the cutter, which gives a better finish and longer tool life in soft, gummy metals.

For hardened steel, use a coated carbide end mill built for high-hardness materials, typically with a TiAlN or AlTiN coating. These handle the heat generated in hardened steel better and resist wear that would blunt an uncoated tool quickly.

A square end mill cuts a sharp 90° internal corner, suited to general-purpose milling. A corner radius end mill has a rounded cutting edge instead, which is stronger and more chip-resistant, making it the better option for heavy cuts or high-speed roughing.

TiAlN and AlTiN coatings suit high-temperature work in steel and alloys. DLC (diamond-like carbon) coatings suit non-ferrous materials like aluminium, where the priority is stopping material sticking to the cutting edge rather than resisting heat.
