Whether you're running a CNC router, engraving machine, or manual milling setup, these precision-ground cutters deliver sharp, clean cuts across a wide range of metals and materials. Available in a 7-piece (1.5–6mm) or 11-piece (1.5–10mm) set, you get the exact diameter you need — right when you need it.

Made in Mainland China.

Why Choose This End Mill Set?

• AlTiN (Titanium Nitride) Coating: Reduces friction and heat buildup, extending tool life and improving surface finish on tough materials.
• 4-Flute Design: Ideal for both roughing and finishing passes — maximises material removal while maintaining a smooth cut.
• High-Speed Steel (HSS) Construction: Tough, heat-resistant steel that holds a sharp edge through demanding machining cycles.
• Wide Diameter Range: From 1.5mm up to 10mm — one set covers fine detail work and heavier stock removal alike.
• Rapid Chip Removal: The 4-flute geometry evacuates chips efficiently, keeping your workpiece and tool cool.
• Versatile Material Compatibility: Suitable for aluminium, copper, mild steel, carbon steel, mold steel, tool steel, structural steel, alloy steel, cast iron, and non-ferrous metals.

Safety & Machining Best Practices

Always wear appropriate personal protective equipment (PPE) — including safety glasses and gloves — when operating CNC or milling machines. For workplace safety guidelines, refer to the OSHA Machine Guarding resource. Ensure correct spindle speed and feed rate for the material being machined to prevent tool breakage and extend cutter life.

Frequently Asked Questions

Q: What materials can I cut with these HSS end mills?

A: These 4-flute titanium-coated HSS end mills are suitable for aluminium, copper, mild steel, carbon steel, mold steel, tool steel, structural steel, alloy steel, cast iron, and non-ferrous metals. They can also be used on wood. They are not recommended for ceramics or stone.

Q: What is the difference between the 7-piece and 11-piece sets?

A: The 7-piece set covers diameters from 1.5mm to 6mm — great for fine detail and lighter milling work. The 11-piece set extends the range up to 10mm, giving you more versatility for heavier stock removal and a wider variety of CNC and engraving applications.

Q: What does the AlTiN (Titanium Nitride) coating do?

A: The AlTiN coating significantly reduces heat and friction during cutting, which prolongs the sharpness and life of each end mill. It also improves performance on harder metals compared to uncoated HSS tools.

Q: Are these end mills compatible with standard CNC routers and engraving machines?

A: Yes. These end mills feature standard shank diameters and are compatible with most CNC routers, engraving machines, and manual milling machines that accept collet chucks in the appropriate size range.
