GM Series end mill that has both high hardness and elastic modulus due to

the use of carbide material and features the reasonable balance with the good cutting quality. It can extend the tool lifespan.

The GM-4R Corner-Radius End Mill is another type of cutting tool used in milling operations, specifically designed for creating rounded corners or fillets in workpieces. Here's a breakdown of its name:

● GM: As previously mentioned, this may refer to the manufacturer or the series of end mills.

● 4R: This typically denotes specific characteristics of the end mill. The "4" may refer to the diameter of the cutting tool, while the "R" indicates that the end mill has a corner radius. The "R" value specifies the radius of the rounded corner. For example, if the end mill is labeled as "4R", it means it has a corner radius of 4 units, where the unit could be millimeters or inches, depending on the measurement system being used.

Corner-radius end mills are commonly used in machining operations where sharp corners are not desired or where stress concentrations at sharp corners need to be minimized. They are particularly useful in roughing and finishing applications, as well as in machining materials prone to chipping or cracking, such as certain metals or composites.

When selecting a corner-radius end mill, factors such as the desired corner radius, the material being machined, the required surface finish, cutting speed, and feed rates are taken into account to ensure efficient and effective machining.
