HRC55 Carbide End Mill

Square end mill: square end mill, called, flat end mill, too. The corners of these mills are sharp and generate a 90° angle. The most popular milling cutters in the industry are made by solid carbide or various compositions of high-speed steel.ThainLong Tool Co., Ltd,, mainly manufactured the solid carbide square end mills. Standard flute diameter of end mills are from D.1 to D20, Standard flute length of end mills are from 3L to 45L, standard shank diameter of end mills are from D4 to D20, standard overall of the flat end mills are from 50L to 150L, non-standard specification of end mills can be manufactured based on your drawings.

Usage: Flat end mills are widely used to process planes, stepped surfaces, grooves, etc.
The small core diameter of the front end can ensure the chip removal is smooth, take away the heat of cutting production, and prevent the production of built-up edge. The big core diameter at the back end enhances the rigidity of cutting tools and improve the surface quality of products.

Special variable pitch profile reduces cutting force and stress on the machine spindle.
