Micro 100 CS-250-090 Chamfer Mill 6 Flute 90 Degree Carbide

Product Description

The MICRO 100 CS-250-090 is a solid carbide chamfer mill designed for chamfering, deburring, and edge-breaking operations on a wide range of workpiece materials. It features a 0.25 inch cutter head diameter with a 90-degree included angle and 6 flutes, producing clean, consistent chamfers in a single pass. At 2.5 inches overall length with a 0.25 inch shank diameter, it fits standard collet and end mill holders found on most CNC machining centers and manual mills. The bright, uncoated finish makes it well-suited for non-ferrous metals and plastics where coating adhesion is not a concern. Right-hand cutting direction is standard for conventional spindle rotation.

This chamfer mill is used in precision machining environments including job shops, production facilities, and tool rooms. It handles chamfering on aluminum, brass, copper, plastics, and softer steels. The double-end geometry and 6-flute configuration support higher feed rates and improved surface finish compared to lower-flute-count tools. Typical applications include edge preparation before threading, deburring after drilling, and countersinking for fastener seating. It is installed and operated by machinists and CNC programmers working on light-to-medium duty machining operations.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision cutting applications
• 6-flute design supports higher feed rates and improved surface finish
• 90-degree included angle for standard chamfering and countersinking geometry
• Double-end type geometry extends tool versatility
• Right-hand cutting direction compatible with standard spindle rotation
• Bright, uncoated finish suited for non-ferrous materials and plastics

Compatibility

Designed as a direct-fit replacement for 0.25 inch shank chamfer mills in standard ER collet chucks, end mill holders, and set-screw style tool holders used on CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by machinists using standard collet or end mill holder tooling. Ensure the machine spindle is fully stopped and the tool holder is clean and free of chips before seating the shank. Verify runout with a dial indicator after clamping to confirm proper seating. Follow the machine manufacturer and tooling manufacturer guidelines for speed and feed parameters appropriate to the workpiece material.
