Seco 02772636 Indexable Square-shoulder End Mill 3/4 in

Product Description

The SECO 02772636 is an indexable square-shoulder end mill designed for high-accuracy milling operations in metal cutting and machining environments. Built on the Turbo 10 platform, this toolholder accepts XO.X 10T3.. insert style inserts and uses a screw-based insert holding method for secure, repeatable seating. The steel body features a 3/4 inch cylindrical shank and delivers a 90-degree lead angle with a negative rake geometry. Through-coolant capability allows direct delivery of coolant to the cutting zone, supporting longer tool life and better chip evacuation. It is suited for CNC machining centers where precision shoulder milling is required.

This end mill is used in production and job-shop milling applications where square shoulders and flat floor finishes are required. The Turbo 10 series is configured for light to medium-duty indexable milling on machining centers running at speeds up to 26,300 RPM. The 2-flute, 2-insert configuration and 0.354 inch maximum depth of cut make it well-suited for moderate axial engagement passes in steel and similar materials. Installation and insert changes are performed by machinists and CNC tooling technicians.
