Power Through Heavy Cuts with Roughing End Mill

When your machining job calls for deep cuts and consistent performance, having the right tool in hand makes all the difference. That’s where the Roughing End Mill tool steps in. Built for general-purpose heavy cutting, this end mill is designed to handle tough materials and demanding operations with ease—making it a go-to solution for manufacturers looking to boost efficiency without compromising on quality.

At the core of this tool is Cobalt High-Speed Steel (HSS-Co), a material chosen specifically for its ability to withstand heat and maintain toughness in high-load conditions. Compared to standard HSS, cobalt HSS delivers improved performance in heavy-duty machining environments.

Having the right tool in hand makes all the difference, especially when your machining hob calls for deep cuts and consistent performance. Built for general purpose heavy cutting, this end mill bit is designed to handle tough materials and demanding operations with ease.

• Higher heat resistance means you can push cutting speeds further
• Greater toughness helps reduce the risk of chipping during interrupted cuts
• Longer tool life leads to better cost-efficiency over time

So, whether you're roughing out steel, stainless, cast iron, or even aluminum and copper alloys, this end mill tool is built to last—and to cut clean.

The Roughing, Long Type Roughing End Mill features a standard torsion helix angle between 30° and 44°. This range strikes a perfect balance between chip evacuation and tool stability, which is key when you're cutting deeper or dealing with tougher materials.

• Efficient chip removal keeps your workspace clean and reduces heat buildup
• Stable cutting reduces tool deflection and vibration
• Consistent results, even in longer operations

One of the standout features of the Roughing End Mill series is its availability in 4, 5, and 6-flute configurations. The more end milling cutter has teeth, the higher rigidity and less vibration it provides, which translates to smoother finishes and higher feed rates. Combined with a straight shank for easy tool holding, this end mill tool bit offers excellent performance across a variety of machine setups.

Common Machining Applications:

• Plane cutting
• Side milling
• Groove cutting
