Description

Product Overview

The 58° Upgraded Solid Carbide End Mills D1-D20mm General Purpose CNC Milling Cutter is designed for precision machining on CNC machining centers and high-speed milling machines. Manufactured from 0.2 μm ultra-fine-grain tungsten carbide and finished with a wear-resistant nano coating, this upgraded milling cutter is engineered to provide cutting stability, wear resistance, and consistent machining performance.

Its optimized 35° helix flute design, thickened core, double-margin structure, and fully ground cutting edges help improve tool rigidity, chip evacuation, and surface finish. Edge passivation and sandblasting treatments further support wear resistance, while multi-stage inspection helps control dimensional accuracy and runout.

Available in diameters from D1 to D20 mm, the cutter is suitable for machining a wide range of metal and non-metal materials with hardness up to HRC 58, subject to material and cutting-condition compatibility. Changzhou Boston Tool Co., Ltd. provides standard tool sizes and supports customized specifications for different machining requirements.
