3 Flute DLC Coated Solid Carbide End Mill for Aluminum | High Performance U-Shape CNC Bit - Changzhou QT TOOLS

Product Function

Designed specifically for high-speed machining of non-ferrous materials, this 3-Flute Solid Carbide End Mill is the ultimate solution for milling Aluminum Alloys, Copper, Brass, and Plastics.

The "U-Shape" groove design solves the most common problem in aluminum machining: chip packing. By ensuring rapid chip evacuation, this tool allows for higher feed rates and superior surface finishes compared to standard end mills.

Product Features

DLC (Diamond-Like Carbon) Coating: Our colorful DLC coating offers an extremely low coefficient of friction (0.1) and high hardness. This effectively prevents "built-up edge" (aluminum sticking to the tool) and extends tool life by 3-5 times compared to uncoated tools.

U-Shape Flute Geometry: Large valley design ensures smooth chip removal even during high-speed slotting and profiling, reducing cutting heat and vibration.

3-Flute Design: The perfect balance between chip space (like a 2-flute) and core strength/finish quality (like a 4-flute).

Double Relief Angle: Enhances the rigidity of the cutting edge and provides a polished surface finish on the workpiece.

Material: Ultra-fine micro-grain Tungsten Carbide substrate (HRC55) ensures high wear resistance and toughness.

FAQ

Q: Why use DLC coating for Aluminum? A: Aluminum is "sticky." Standard TiAlN coatings often react with aluminum, causing the material to weld to the tool (BUE). DLC (Diamond-Like Carbon) has a very low friction coefficient and high hardness, ensuring the aluminum slides off, leaving a mirror finish.

Q: Can this tool cut Steel or Stainless Steel? A: No. This geometry and coating are optimized for non-ferrous metals. For Steel or Stainless Steel, please check our 4-Flute AlTiN coated series.

Q: Do you offer OEM/ODM services? A: Yes! We can laser mark your logo on the shank and produce custom geometries or lengths based on your drawings.

Q: What is the delivery time? A: Stock items ship within 24-48 hours. Custom orders typically take 7-10 days.
