4-Flute 3mm Carbide End Mill – Extra Long 75mm Shank CNC Tool
4-Flute 3mm Carbide End Mill – Extra Long 75mm Shank CNC Tool
4-Flute Carbide End Mill – 3mm, Extra Long Shank 75mm
Precision-engineered for demanding industrial and CNC machining applications, this 4-flute carbide end mill delivers outstanding cutting performance on general steel, alloy steel, and die steel. With an extra-long 75mm overall length and a straight shank design, it reaches deep into workpieces where standard-length tools simply cannot. The carbide construction provides excellent hot hardness and oxidation resistance, keeping your cuts accurate even during high-speed operations. Made in Mainland China.

Frequently Asked Questions
Q: What materials can this 3mm carbide end mill cut?
A: This 4-flute carbide end mill is designed for general steel, alloy steel, and die steel up to HRC45 hardness. Its solid carbide construction and hot hardness properties make it suitable for a wide range of ferrous metals commonly machined in industrial and CNC workshop settings.
Q: What is the total length and cutting length of this end mill?
A: The overall length (L) of this end mill is 75mm, making it an extra-long shank tool ideal for deep-pocket milling. The blade (cutting) length (L1) is 12mm, and both the head and shank diameter are 3mm.
Q: Is this end mill compatible with CNC milling machines?
A: Yes. The straight 3mm long shank is compatible with standard ER collet chucks used on most CNC machining centres and manual milling machines. Always verify your machine's collet size matches the 3mm shank diameter before use.
Q: How many pieces are included in the package?
A: Each order includes 1 × 4-flute carbide end mill (Model: CAE3-3X3, 3mm diameter, 75mm overall length). If you need multiple units, simply adjust the quantity before adding to your cart.
