Solid Carbide Milling Cutters for Hard Machining

Walter USA has introduced its ISO H Advance line of solid carbide milling cutters, consisting of seven new cutter families tailored to the requirements of hard machining of workpieces as hard as 63 HRC. These new cutters include mini and multi-flute, shoulder/slot, ballnose, and high-feed milling cutters, covering the full range of solid carbide milling. The WB10TG grade is said to achieve long tool life and high surface quality, and Walter's performance-enhancing geometry is said to yield high metal removal rates.

Suitable for a range of applications, the cutters can be applied for large or small components as well as for various milling strategies such as roughing, finishing, high-feed milling and, in the case of the ballnose mill, machining 3D contours. Their properties make them particularly beneficial for users with medium-size batches and high quality requirements. They are also ideal for users seeking high performance and excellent price-to-performance ratio. Typical areas of application include die and moldmaking as well as general metalworking.

The specific tool families are designated MC089, MC183, MC187, MC281, MC388, MC480 and MC482. MC089 is for high-feed cutting and pre-finishing. MC183, featuring a high number of teeth, is targeted at side milling and finishing. MC187 is aimed at side milling, dynamic milling and finishing. MC281 features mini end mills from 0.04" to 0.16" (1 to 4 mm) with corner radius. MC388 is for both roughing and finishing, providing universal usage for ISO H and ISO P machining. MC480 are mini ballnose end mills from 0.02" to 0.20" (0.4 to 5 mm) for copy milling of 3D contours. Finally, the MC482 family consists of ballnose end mills with two and four flutes for copy milling of 3D contours.
