What is a rougher end mill?

Knuckle Rougher End Mills have a serrated cutting edge that generates significantly smaller chips than a standard end mill cutting edge. Designed for steels, Knuckle Rougher End Mills are built to withstand harder materials and feature a large core.

What is a roughing end mill used for?

Roughing End Mills, also known as ripping cutters or hoggers, are designed to remove large amounts of metal quickly and more efficiently than standard end mills.

How long are end mills?

Available with overall lengths as long as 12 inches and flute lengths up to 8 inches long. End mill types available include 2-flute, 4-flute, square end, ball end, uncoated or ALTiN coated.

What can Regal roughing end mills be used for?

Select Regal roughing end mills for difficult roughing of hardened steels or high velocity milling of aluminum and other non-ferrous materials. These 20 degree helix tools in both coarse and fine pitch tools are made from sub micro-grain carbide and designed for either wet or dry high speed milling applications in either tool or hardened steel.

What makes roughing carbide end mills so effective?

Multi-flute Triple Crown carbide fine pitch AlCrN coated roughing end mills with radius are designed for volume material removal where deflection can be an issue. The variable helix eliminates harmonic vibration and enhances chip evacuation. This multi-layer coating provides outstanding resistance to wear and abrasion to insure maximum tool life.

Which is better roughing or high efficiency milling?

While traditional roughing is occasionally necessary or optimal, it is generally inferior to High Efficiency Milling (HEM). HEM is a roughing technique that uses a lower Radial Depth of Cut (RDOC) and a higher Axial Depth of Cut (ADOC). This spreads wear evenly across the cutting edge, dissipates heat, and reduces the chance of tool failure.

What kind of rougher for cobalt end mills?

A Cobalt coarse pitch rougher for high stock removal in difficult to machine materials. Center holes at both ends enables a user to resharpen the end mill by grinding the face of the flute without distorting the roughing form. A Cobalt fine pitch rougher for high stock removal in difficult to machine materials.
