Kyocera OTM86112 Indexable Chamfer End Mill 0.563in

Product Description

The KYOCERA OTM86112 is an indexable chamfer end mill designed for precision chamfering and facing operations on CNC machining centers and milling machines. It accepts XPMT 0902.. series inserts and holds two inserts simultaneously, allowing efficient material removal at a 45-degree lead angle. The tool has a cutting diameter of 0.563 inches, an overall length of 2.91 inches, and a shank diameter of 0.625 inches with a whistle notch shank type. Insert retention is handled by a screw-lock method for repeatable, secure seating during high-speed passes.

This end mill is suited for right-hand cutting applications in production and job-shop environments. The CM toolholder style and whistle notch shank make it compatible with standard milling setups where consistent chamfer geometry is required. Typical applications include facing operations on ferrous and non-ferrous workpieces where a controlled 45-degree chamfer edge must be held across multiple parts. The 0.24-inch maximum depth of cut keeps this tool in the category of finish and semi-finish chamfering rather than heavy roughing.

Key Features

• 45-degree lead angle for consistent chamfer geometry on faced surfaces
• Accepts XPMT 090208, XPMT 090216, and XPMT 090224 insert sizes
• Two-insert configuration for balanced cutting and improved feed rates
• Whistle notch shank provides positive drive and prevents shank pullout
• Screw-lock insert holding method for reliable insert indexing and repeatability
• No coolant-through design — suitable for conventional coolant flood or dry cutting setups

Compatibility

Compatible insert styles are XPMT 090208, XPMT 090216, and XPMT 090224. Toolholder style is CM. Designed for use in right-hand milling applications requiring a 45-degree chamfer end mill with a 0.625-inch whistle notch shank.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Secure the whistle notch shank fully into the tool holder before tightening, and torque the insert clamping screws according to the insert manufacturer specifications for the XPMT series. Verify runout with a dial indicator before beginning cuts. Always power down and lock out the spindle before changing inserts or removing the tool from the holder.
