Carbide End Mill for Aluminium

The SPEED TIGER IAUE3-8-3 is a solid carbide square end mill with a 3/8 inch diameter and three flutes. It features a high-feed U-type geometry designed for high material removal rates when slotting aluminium and copper alloys. The flutes are ground in an ISO-9001 certified factory and the tool is supplied uncoated.

Machinists Cutting Aluminium and Copper Alloys

This cutter suits CNC operators and manual machinists who need effective chip evacuation while roughing or finishing non-ferrous metals. The strong tooth design with double relief angles supports higher feed speeds in these specific materials. It is not intended for stainless steel, titanium, Inconel or general steel machining where coated alternatives perform better.

Uncoated 3-Flute U-Type Geometry

The defining specification is the uncoated, three-flute U-type profile optimised for aluminium and copper alloys. This geometry drives the high feed capability and chip removal performance that determines whether the tool matches the application.

Questions about this item

What comes in the package and what else is needed to use this 3/8" end mill?

The package contains one carbide end mill with three flutes and a 3/8" cutting diameter. You will need a compatible tool holder or collet that accepts a 3/8" shank, plus a milling machine or CNC router capable of the required speeds and feeds for aluminium.

How do I decide between the different IAUE sizes listed from 1/8" to 5/8"?

Choose the diameter that matches the feature size and material removal rate you need; smaller diameters suit fine detail and tight corners, while larger diameters such as this 3/8" tool remove more material per pass in aluminium and copper alloys.

What does the uncoated carbide and U-type flute design mean for real-world aluminium cutting?

The uncoated carbide with U-type geometry provides sharp cutting edges and generous chip space, allowing high feed rates and effective chip evacuation in aluminium and copper alloys for both roughing and finishing passes.
