Seco 02789772 Indexable High-feed End Mill 1.26 in

Product Description

The SECO 02789772 is an indexable high-feed end mill designed for aggressive material removal at shallow depths of cut. It accepts 2 LP06 inserts secured by screw, delivering consistent edge positioning and fast insert changes at the machine. With a maximum cutting diameter of 1.26 inches and a maximum depth of cut of 0.03 inches, this tool is engineered for high-feed milling strategies where chip load is converted to axial force rather than radial deflection. A through-coolant design channels fluid directly to the cutting zone, extending insert life and improving chip evacuation in demanding applications.

This end mill is suited for milling operations in metalworking environments, including roughing and semi-finishing passes on ferrous and non-ferrous materials. The Toolholder Style R217.21 with a modular shank and M8 modular connection makes it compatible with modular tooling systems common in CNC machining centers. The cutting range spans a minimum cutting diameter of 0.29 inches up to the full 1.26 inches, offering flexibility across varied pocket and contour milling operations. Machinists and tooling specialists working in job shops or production environments will find it suited to high-speed, low-engagement strategies.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with CNC milling setups. Ensure the machine spindle is fully stopped and the tool changer is disabled before mounting or changing inserts. Use the appropriate Torx or hex key to seat insert screws to the tool manufacturer torque specification. Confirm runout and tool projection length before initiating a cutting program.
