Built around the R218.20 toolholder style, it accepts two 218.20-0.250.R screw-held inserts and features a through-coolant design that delivers cutting fluid directly to the tool tip. The 1\/2 inch cutting diameter and 3\/4 inch Weldon Flat shank provide rigid, positive drive with minimal runout. With a maximum spindle speed of 30,000 RPM and a maximum ramping angle of 45 degrees, this end mill is suited for dynamic milling strategies including plunge, ramp, and contour operations. Licensed machinists and CNC tooling specialists are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in CNC machining centers handling milling operations on ferrous and non-ferrous materials. The Weldon Flat shank seats securely in standard end mill holders with set screw retention. The through-coolant capability makes it well suited for deep pocket milling and high-material-removal-rate passes where heat management is critical. The 4.33 inch overall length allows access to moderate-depth features without excessive overhang.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2 inch cutting diameter with 0.433 inch maximum depth of cut\u003c\/li\u003e\n  \u003cli\u003e2-flute ball nose geometry for contour, ramp, and finish milling\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design directs coolant to the cutting zone\u003c\/li\u003e\n  \u003cli\u003eMaximum ramping angle of 45 degrees supports aggressive helical entry\u003c\/li\u003e\n  \u003cli\u003eAccepts two 218.20-0.250.R indexable inserts retained by screw\u003c\/li\u003e\n  \u003cli\u003eMaximum spindle speed of 30,000 RPM\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch Weldon Flat shank for positive set-screw drive\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 218.20-0.250.R inserts and compatible with the R218.20-Inch series tooling system.
