RobbJack C1-401-08-DLC | 0.250" Diameter x 0.250" Shank x 2.500" OAL 4 Flute DLC Coated Square End Mill

Description

The RobbJack C1-401-08-DLC is a high-performance 1/4 carbide square end mill made for demanding industrial applications requiring extreme precision. Featuring a specialized Diamond-Like Carbon finish, this 1/4 dlc coated end mill provides exceptional surface hardness and lubricity to prevent material adhesion. The 4 flute square end mill design is perfectly balanced to provide superior chip evacuation while maintaining a high-quality surface finish on every workpiece. As a premier robbjack square end mill, it excels in machining non-ferrous materials such as aluminum, plastics, and highly abrasive graphite. With a 0.2500" cutting diameter and a matching shank, this tool ensures maximum rigidity for precision slotting and intricate profiling tasks. The 0.250 carbide square end mill incorporates a 30-degree helix angle designed to shear through soft materials smoothly while minimizing heat generation. This 4-flute DLC-coated end mill belongs to the C1 series, renowned for its tight tolerances and exceptional runout control in modern CNC environments. Utilizing a 1/4 diameter milling end mill with DLC coating significantly reduces the coefficient of friction, effectively preventing built-up edges on the tool. The 2.5-inch overall length offers the reach necessary for deep pocketing while preserving the structural strength of the solid carbide core. Machinists trust the RobbJack C1-401-08-DLC for its ability to maintain a sharp cutting edge over extended production runs in tough, abrasive materials. This square end mill configuration is essential for creating flat-bottom cuts and sharp internal corners for mechanical components with strict blueprints. By integrating this 1/4 carbide square end mill into your shop, you can achieve higher feed rates and lower cycle times without risking premature tool failure. The right-hand cutting direction combined with a right-hand helix pulls chips away from the cut zone to maintain a clean machining path. This robbjack square end mill is a versatile solution for the medical, aerospace, and electronics industries, where dimensional accuracy is absolutely critical. Choosing the 1/4 dlc coated end mill ensures a professional-grade finish and unmatched durability for high-speed milling operations across various non-ferrous alloys.
