End Mill, 5pcs M3-M8 4 Flutes HSS-AL Slotted Milling Cutter Drill Bits HRC6568° Metal Milling Cutter for Copper, Aluminum, Steel, Cast Iron

Description: The milling cutter is a special tool used to cut a hole for the head of a bolt or screw. This type of hole cuts and bottoms with high alignment accuracy. Due to its high production efficiency, it is commonly used in machining.

Features: The milling cutters are made of high-speed steel and are usually mounted on a milling machine.

Suitable for milling copper, aluminum, steel, cast iron, etc. High toughness, abrasion resistance, and high-speed cutting result in high hardness. Machining can be done directly or through heat treatment in the mold. Reduces tool change times, improves the efficiency of machine actuator movements, and saves time in mold making.
