4-Flute HSS Titanium End Mill Set – 7 or 11 Pieces | 1.5–10mm CNC Milling Cutters

Upgrade your CNC machine, engraving router, or milling station with this professional-grade 4-Flute High Speed Steel (HSS) Titanium-Coated End Mill Set. Available in a 7-piece (1.5–6mm) or 11-piece (1.5–10mm) set, these cutters are designed to deliver precise, clean cuts through a wide range of materials including wood, aluminum, copper, carbon steel, mold steel, alloy steel, cast iron, and other non-ferrous metals.

Featuring an AlTiN (Aluminum Titanium Nitride) coating, each end mill offers superior heat resistance, extended tool life, and reduced friction — ideal for both roughing and finishing passes.

Key Features

• 4-Flute Design: Sharp cutting edges deliver fast material removal with excellent surface finish quality.
• AlTiN Titanium Coating: Dramatically increases hardness, wear resistance, and heat tolerance compared to uncoated HSS tools.
• HSS Material: High Speed Steel construction balances toughness and cutting performance across a variety of workpiece materials.
• Rapid Chip Evacuation: Optimized flute geometry clears chips quickly, reducing heat buildup and extending cutter life.
• Wide Size Range: Covers the most common milling diameters in a single set — no need to buy cutters individually.
• Versatile Compatibility: Works with CNC milling machines, engraving machines, and similar machining centers.
• Not suitable for: Ceramics or stone.

Frequently Asked Questions

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

A: These 4-flute HSS AlTiN-coated end mills are suitable for milling wood, aluminum, copper, carbon steel, mold steel, tool steel, cast iron, structural steel, alloy steel, and other non-ferrous metals. 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 includes cutters ranging from 1.5mm to 6mm diameter with a 6mm shank. The 11-piece set provides a broader range from 1.5mm to 10mm with a 10mm shank, making it ideal for operators who need maximum versatility for various CNC milling and engraving tasks.

Q: What does the AlTiN coating do for these end mills?

A: The AlTiN (Aluminum Titanium Nitride) coating significantly increases the hardness and heat resistance of each end mill. This means less tool wear, longer cutter lifespan, reduced friction during cutting, and better performance at higher speeds compared to standard uncoated HSS tools.

Q: Are these end mills compatible with my CNC machine?

A: Yes — these end mills are designed for use with standard CNC milling machines and engraving machines that accept 6mm, 8mm, or 10mm shank diameters, depending on the set you choose. Always verify your machine's collet size before ordering.
