Description
Product Overview
The SPEED TIGER Micrograin Carbide Square End Mill is engineered for demanding machining tasks across a wide range of steel alloys. Featuring a robust 4‑flute design, the tool delivers consistent chip evacuation and superior surface finish. Its 5/16″ cutting diameter and full 4″ length provide an extra‑long reach, allowing deep cuts in thick workpieces while maintaining rigidity. The shank matches the cutting diameter, ensuring optimal power transmission from the spindle to the cutting edges. Constructed from high‑grade carbide and coated with AlTiBN (aluminum titanium boron nitride), the end mill offers exceptional heat resistance, surpassing traditional TiAlN, TiN, and TiCN coatings. This combination of material and coating enables the tool to withstand the high temperatures generated during high‑speed milling of hardened steels up to HRC54, delivering reliable performance without premature wear.
Usage
Designed for both professional machinists and dedicated DIYers, this end mill excels in a variety of applications. It is ideal for milling alloy steels (HB225‑325), pre‑hardened steels up to HRC45, and fully hardened steels ranging from HRC40‑54. The tool’s precise geometry and tight tolerance of -0.02mm enable users to achieve tight tolerances in aerospace components, automotive parts, and custom tooling projects. Whether you are working on a CNC mill or a manual vertical mill, the extra‑long reach allows you to clear deep pockets and intricate features without sacrificing stability. The tool’s versatility also extends to non‑ferrous metals such as cast iron and certain aluminum alloys, making it a valuable addition to any machining toolbox.

FAQ
What materials can this end mill effectively cut?
The end mill is optimized for alloy steels (HB225‑325), pre‑hardened steels up to HRC45, and fully hardened steels up to HRC54. It also performs well on cast iron and selected non‑ferrous metals such as certain aluminum alloys.
How does the AlTiBN coating compare to traditional TiN or TiAlN coatings?
AlTiBN offers higher thermal stability, allowing the tool to operate at higher cutting speeds without degradation. This results in longer tool life and reduced downtime compared to TiN or TiAlN coated tools.
Can I use this end mill on a standard CNC machine?
Yes, the tool’s shank diameter matches the cutting diameter, making it compatible with most CNC spindle collets and manual mill chucks. Ensure the machine’s spindle speed and feed rates are set according to the material being machined.
What is the recommended cutting speed for hardened steel?
For hardened steel up to HRC54, a cutting speed of 80‑120 m/min with a moderate feed per tooth (0.04‑0.06 mm) is recommended. Adjust parameters based on specific alloy composition and machine rigidity.
