Kyocera OTM86116 Indexable Chamfer End Mill

Product Description

The KYOCERA OTM86116 is an indexable chamfer end mill designed for facing operations in metal cutting applications. It features a 45-degree lead angle and accepts two APET 1604 screw-held inserts, allowing for fast insert changes without removing the toolholder from the machine. The cutter covers a cutting diameter range of 0.8 to 1.65 inches with a maximum depth of cut of 0.44 inches. The tool measures 3.25 inches in overall length and uses a CM-style toolholder interface with a 0.75-inch whistle notch shank. This tool is typically set up and operated by machinists and CNC technicians working in production or job shop environments.

The OTM86116 is suited for facing and chamfering operations on milling machines and machining centers. The right-hand cutting direction and whistle notch shank make it compatible with standard vertical and horizontal milling setups. With a head length of 1.35 inches and a shank length of 2.031 inches, it fits typical toolholder reach requirements in production milling. Coolant-through capability is not included, so external or flood coolant delivery is the standard approach for chip evacuation and heat management.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the toolholder. Confirm insert seating and screw torque per the insert manufacturer guidelines before initiating a cut. Verify shank clamping force meets the toolholder specification to prevent pullout during facing passes.
