7–10 Pc 4-Flute Titanium HSS End Mill Set 1.5–10mm CNC Router

7 or 10-Piece Titanium-Coated HSS End Mill Set – 1.5 to 10mm | CNC Milling Cutters for Wood, Steel & Aluminum

Take your CNC machining, engraving, and milling projects to the next level with this professional-grade 4-Flute Titanium-Coated HSS End Mill Set. Whether you're cutting mild steel, aluminum, copper, mold steel, or wood, these high-speed steel milling cutters deliver sharp, consistent results for both roughing and finishing operations.

Available in a 7-piece set (1.5–6mm) or a 10-piece set (1.5–10mm), this kit gives you versatile diameter coverage for a wide range of CNC router and milling machine applications. The titanium (AlTiN) coating dramatically extends tool life, reduces friction, and improves heat resistance — making these bits a reliable choice for hobbyists and professionals alike.

Made in Mainland China.

Key Features

• 4-Flute Design: Ultra-sharp cutting edges optimized for both roughing and fine finishing cuts.
• Titanium AlTiN Coating: Reduces heat buildup, minimizes wear, and extends the lifespan of each bit.
• High-Speed Steel (HSS) Construction: HRC 63–66 hardness for impressive durability and cutting performance.
• Rapid Chip Removal: Efficient flute geometry evacuates chips quickly, preventing clogging and overheating.
• Wide Diameter Range: 1.5 / 2 / 2.5 / 3 / 4 / 5 / 6mm (7-pc) or 1.5–10mm (10-pc) for diverse job requirements.
• Versatile Material Compatibility: Suitable for copper, carbon steel, mold steel, aluminum, structural steel, alloy steel, cast iron, and wood. Not recommended for ceramics or stone.

Frequently Asked Questions

Q: What materials can these titanium-coated HSS end mills cut?

A: These 4-flute HSS end mills with titanium AlTiN coating are compatible with a wide range of materials including mild steel, carbon steel, mold steel, alloy steel, structural steel, cast iron, aluminum, copper, and wood. They are not recommended for ceramics or stone, as the hardness of those materials can damage the cutting edges.

Q: What is the difference between the 7-piece and 10-piece set?

A: The 7-piece set includes end mills ranging from 1.5mm to 6mm in diameter, ideal for finer or smaller-scale CNC work. The 10-piece set extends the range up to 10mm, covering larger cutting diameters for more demanding milling and routing tasks. Choose based on the diameter range your projects require.

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

A: Yes. These end mills feature standard shank diameters and are designed for use with CNC routers, CNC milling machines, and engraving machines. Always verify that the shank diameter matches your machine's collet size before use.

Q: What does the AlTiN titanium coating do?

A: The AlTiN (Aluminum Titanium Nitride) coating significantly improves heat resistance and hardness at the cutting surface, reducing friction during high-speed cutting. This extends tool life, helps maintain sharper edges longer, and improves chip evacuation compared to uncoated HSS tools.

Q: How do I maintain and store these milling cutters?

A: After each use, clean the end mills to remove chips and debris. Store them in the included set holder or a protective case to prevent edge chipping. Avoid contact with ceramics, stone, or abrasive surfaces. Running at appropriate feeds and speeds for your material will maximize the lifespan of the titanium coating.
