It carries the ISO designation M1D075E1003C075L670 and accepts three EC10.. or EP10.. series inserts secured by screw clamping. The cutter delivers a 3\/4-inch cutting diameter with a maximum depth of cut of 0.398 inches and a 0 degree lead angle, producing true 90-degree shoulders on workpieces. Through-coolant capability is standard, with a 0.236-inch coolant hole diameter to direct fluid directly to the cutting zone. The 3\/4-inch cylindrical shank fits common milling machine and machining center spindles. Licensed machinists and CNC operators working in production or job-shop environments are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for square-shoulder milling, face milling, and slot milling on ferrous and non-ferrous materials in both conventional and CNC machining centers. The Cutter Style Mill 1-10 designation is compatible with standard tooling setups. With a maximum spindle speed of 45,900 RPM and an overall length of 6.7 inches, it accommodates a range of reach and clearance requirements in horizontal and vertical milling setups. The 1.25-inch head length provides adequate tool engagement without excessive overhang for most typical workholding arrangements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4-inch cutting diameter with 0 degree lead angle for true square-shoulder profiles\u003c\/li\u003e\n\u003cli\u003eAccepts 3 EC10.. and EP10.. series indexable inserts with screw clamping\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design with 0.236-inch coolant hole for direct cutting zone cooling\u003c\/li\u003e\n\u003cli\u003eMaximum spindle speed of 45,900 RPM for high-productivity applications\u003c\/li\u003e\n\u003cli\u003e3\/4-inch cylindrical shank for broad spindle compatibility\u003c\/li\u003e\n\u003cli\u003eISO designation M1D075E1003C075L670 for precise cross-reference and tooling catalog matching\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with EC10.. and EP10.. series indexable inserts.
