Kyocera OTM86132 Indexable Chamfer End Mill 1 in

Product Description

The KYOCERA OTM86132 is an indexable chamfer end mill designed for facing and chamfering operations in metalworking applications. Built to a 50-degree lead angle with a 1-inch cutting diameter, this tool accepts XPMT 15T3 series inserts secured by screw clamping. It holds 2 inserts simultaneously and runs in a right-hand cutting direction. The overall length is 3.15 inches with a 0.75-inch shank diameter machined with a whistle notch for positive retention. Maximum depth of cut reaches 0.376 inches. The CM toolholder series designation makes this a straightforward drop-in for CM-compatible setups used by machinists and tooling engineers in production and job-shop environments.

This chamfer end mill is suited for facing operations on ferrous and non-ferrous workpiece materials in CNC machining centers. The whistle notch shank provides secure tool holding in side-lock style holders. With a 1.25-inch head length and a 0.454-inch width, the OTM86132 fits standard production chamfering and edge-prep work. It does not include through-coolant capability, so external coolant delivery should be used when cutting conditions require it. The tool is compatible with the full XPMT 15T3 insert family, giving the operator flexibility to select the appropriate grade for the material being cut.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before mounting or changing inserts or seating the tool in the holder. Use a calibrated torque driver when securing insert screws to avoid over-torquing or stripping the clamping screw. Verify tool runout after installation and before initiating a cut cycle.
