HSS Roughing End Mill | Coarse & Fine Pitch

BB Tool HSS Roughing End Mills are designed for efficient stock removal. The serrated cutting edges divide chips into smaller sections, helping reduce cutting load and chatter compared with a conventional smooth-edge end mill during roughing operations.

Choose the Tooth Pitch First

Coarse pitch: provides larger chip spaces and is a practical starting point for heavier stock removal.
Fine pitch: uses more cutting teeth and can provide a smoother roughing result under stable conditions.

Available Configurations

This product page contains multiple flute, coating, diameter, flute-length and overall-length combinations. TiN-coated and uncoated options may be listed. Always check the complete variant name before ordering.

How to Select a Variant

Choose coarse or fine pitch for the required roughing strategy.
Confirm the flute and coating option shown in the variant.
Match the cutting diameter and shank diameter to the feature and holder.
Select sufficient flute length, using the shortest practical overall length for rigidity.

Machining Note

Roughing conditions depend on tool diameter, tooth pitch, workpiece, machine power, setup rigidity and coolant strategy. Begin with conservative engagement and adjust using the applicable shop data or cutting-condition chart.
