4-Flute HSS End Mill Set | TiN Coated CNC Milling Cutters 1.5–10mm

SLADE 4-Flute Titanium-Coated HSS End Mill Set – 7, 10 & 11 Piece Options

Upgrade your CNC routing, engraving, and milling work with the SLADE 4-Flute High Speed Steel End Mill Set. Available in 7-piece, 10-piece, and 11-piece configurations covering diameters from 1.5mm to 10mm, these titanium-coated (AlTiN) milling cutters deliver sharp, clean cuts on a wide range of materials — from aluminum and copper to carbon steel, mold steel, and alloy steel.

Whether you're a hobbyist machinist or a professional CNC operator, this set gives you the versatility to handle both roughing and finishing passes with confidence.

Key Features

• 4-Flute Design – Maximizes material removal rate while maintaining a superior surface finish on both roughing and finishing operations.
• AlTiN (Titanium) Coating – Reduces friction and heat buildup, extending tool life significantly compared to uncoated bits.
• High Speed Steel (HSS) Construction – Tough, wear-resistant material ideal for CNC machines, engraving machines, and milling centers.
• Wide Diameter Range – Choose from sets covering 1.5mm to 6mm (7-piece), 1.5mm to 8mm (10-piece), or 1.5mm to 10mm (11-piece) for maximum flexibility.
• Rapid Chip Removal – Flute geometry promotes efficient chip evacuation, reducing heat and improving cut quality.
• Versatile Material Compatibility – Suitable for mild steel, aluminum, copper, iron, carbon steel, mold steel, tool steel, cast iron, titanium alloys, and other non-ferrous metals.
• Sharp Cutting Edges – Precision-ground edges ensure accurate, repeatable results across every diameter in the set.

Frequently Asked Questions

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

A: These 4-flute HSS end mills with AlTiN coating are compatible with a wide range of materials including aluminum, copper, mild steel, carbon steel, mold steel, tool steel, cast iron, alloy steel, titanium, wood, and non-ferrous metals. They are not recommended for ceramics or stone, as these materials require specialized diamond or carbide tooling.

Q: What is the difference between the 7-piece, 10-piece, and 11-piece sets?

A: The 7-piece set covers diameters from 1.5mm to 6mm, the 10-piece set covers 1.5mm to 8mm, and the 11-piece set covers the full range from 1.5mm to 10mm. Choose the set that best matches the range of diameters you most commonly need for your CNC or milling work.

Q: What does the AlTiN (titanium) coating do for the end mills?

A: The AlTiN (Aluminum Titanium Nitride) coating significantly reduces friction and heat buildup during machining. This helps extend the life of each cutter, allows for higher cutting speeds, and produces a cleaner finish compared to uncoated HSS end mills.

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

A: Yes. The 4-flute geometry with sharp cutting edges makes these end mills well-suited for both roughing operations (material removal) and finishing passes (surface quality). The rapid chip evacuation design also helps keep the tool cool during extended use.

Q: What CNC machines are these compatible with?

A: These end mills are compatible with standard CNC milling machines, engraving machines, and other milling centers that accept the corresponding shank diameters (1.5mm–10mm). Always verify your machine's collet size before purchasing.
