Deep Groove End Mill

Item No.: DGB/F/R
The carbide deep groove end mill is designed for high-precision machining of deep cavities, narrow slots, and hard-to-reach areas. Made from solid tungsten carbide with a long reach and reduced neck design, it provides excellent rigidity and chip evacuation in deep cutting operations. Ideal for CNC milling of molds, dies, and components with deep profiles, this end mill ensures smooth cutting and dimensional accuracy. Coated with TiSiN or NaCo4 for superior wear resistance and heat stability, it delivers reliable performance in both steel and stainless-steel machining.

Applications



1.Deep Slot and Groove Machining – Perfect for cutting narrow and deep channels in molds, dies, and metal parts.

2.Mold Cavity Milling – Ideal for deep cavity shaping and fine contour finishing in mold manufacturing.

3.Reduced Neck Machining – Designed for tight spaces and long-reach areas without tool interference.

4.Precision CNC Milling – Ensures high accuracy in deep pocket and contour machining applications.

5.High-Speed Machining – Suitable for steel, stainless steel, and alloy materials under high-speed cutting conditions.


Advantages



​​​​​​​1.Long Reach Design – Extended flute and reduced neck allow deep cutting in confined

2.High Rigidity and Stability – Solid carbide construction maintains strength and precision during deep slot machining.

3.Superior Chip Evacuation – Optimized flute design prevents chip clogging and overheating in deep grooves.

4.Wear and Heat Resistance – TiSiN and NaCo4 coatings enhance durability under continuous heavy cutting.

5.Precision Surface Finish – Achieves accurate and smooth finishes in deep and narrow cavity milling.
