4-Flute Titanium HSS End Mill Set 1.5–10mm | CNC Router Bits

7 or 10-Piece Titanium-Coated HSS End Mill Set – Precision CNC Milling Made Easy

Upgrade your CNC machine, engraver, or milling setup with this professional-grade 4-flute, titanium-coated High Speed Steel (HSS) end mill set. Available in a 7-piece (1.5–6mm) or 10-piece (1.5–10mm) set, these versatile router bits are engineered for sharp, clean cuts through a wide range of materials — from wood and aluminum to mold steel and cast iron.

Made in Mainland China.

Why Choose This End Mill Set?

• AlTiN Titanium Coating: The advanced aluminum titanium nitride coating dramatically reduces friction and heat build-up, extending tool life significantly compared to uncoated bits.
• 4-Flute Design: Ideal for both roughing and finishing passes, delivering smooth surface finishes and rapid chip evacuation.
• Hardness HRC 63–66: High Speed Steel core with extreme hardness ensures durability and resistance to wear under heavy milling loads.
• Wide Size Range: Diameters from 1.5mm to 10mm cover virtually every common CNC milling task in one convenient set.
• Multi-Material Compatibility: Suitable for wood, copper, carbon steel, mold steel, tool steel, cast iron, structural steel, alloy steel, aluminum, and other non-ferrous metals. Not recommended for ceramics or stone.

Frequently Asked Questions

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

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

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, while the 10-piece set covers 1.5mm to 10mm. Choose the 10-piece set if you need larger diameter cutters (7mm, 8mm, 9mm, and 10mm) for broader milling operations on your CNC router or machine.

Q: Are these end mills suitable for both roughing and finishing passes?

A: Yes! The 4-flute design with sharp cutting edges makes these end mills excellent for both roughing (material removal) and finishing (smooth surface) operations. The titanium AlTiN coating helps manage heat during both types of cuts, extending the working life of each bit.

Q: What CNC machines are these end mills compatible with?

A: These router bits are designed for standard CNC milling machines, CNC routers, engraving machines, and machining centers that accept shank sizes within the 1.5–10mm diameter range. Always verify your machine's collet size before ordering.
