Description
Product Overview
The SPEED TIGER Micrograin Carbide End Mill is engineered for demanding metalworking applications. Constructed from micrograin carbide, the tool delivers superior toughness and wear resistance, allowing it to maintain sharp cutting edges even when machining tough alloys and hardened steels. The four‑flute design provides a balanced chip evacuation and rigidity, while the AlTiBN coating adds high‑temperature stability, reducing thermal deformation during extended runs. With a 1/4″ diameter, 4‑flute configuration, and a 4″ overall length, this end mill fits standard CNC spindle chucks and offers a compact footprint for tight machining spaces. The product dimensions are 0.23 x 0.23 x 2.99 inches, weighing just 2.4 ounces, making it easy to handle and store. The set includes two pieces, ensuring you have a spare ready for continuous production.
Usage
This end mill excels in a variety of industrial scenarios. It is ideal for CNC milling of alloy steels ranging from HB225 to HB325, pre‑hardened steels up to HRC45, and hardened steels up to HRC46. Machinists can use it for pocketing, contouring, and slotting operations where high precision and surface finish are critical. The tool’s micrograin carbide core tolerates the high cutting forces generated by hardened materials, while the AlTiBN coating protects against oxidation and wear at elevated temperatures. Whether you are producing aerospace components, automotive parts, or precision tooling, the end mill delivers consistent performance. Its -0.02 mm error rating ensures tight dimensional control, making it suitable for parts that require exacting tolerances.

FAQ
What materials can this end mill safely cut?
The mill is designed for carbon steels, alloy steels, pre‑hardened steels up to HRC45, and hardened steels up to HRC46. It also performs well on cast iron and other common industrial alloys.
How does the AlTiBN coating compare to standard TiN?
AlTiBN provides higher thermal stability, allowing the tool to operate at higher temperatures without losing hardness. This results in longer tool life and more consistent performance compared to standard TiN, TiAlN, or TiCN coatings.
Can I use this end mill for high‑speed machining?
Yes. The combination of micrograin carbide and AlTiBN coating makes the tool suitable for high‑speed applications, provided you follow recommended feed and speed parameters for the material being machined.
What is the recommended spindle speed for hardened steel?
For hardened steel (HRC40‑46), a spindle speed of 8,000–10,000 RPM with a moderate feed rate is typically effective. Adjust parameters based on chip load and machine rigidity.
Do you offer technical support for cutting parameters?
Absolutely. Our support team can provide detailed cutting condition charts and help you fine‑tune parameters for optimal performance on your specific material and machine setup.
