Helical Solutions 07009 Chamfer Mill 0.375 in 3 Flute Carbide

Product Description

The HELICAL SOLUTIONS 07009 is a solid carbide chamfer mill designed for chamfering, deburring, and edge-breaking operations on ferrous and non-ferrous materials. The cutter features a 90-degree included angle with a 45-degree included side angle, a 0.375-inch cutter head diameter, and three flutes ground for right-hand cutting. The APLUS coating improves wear resistance and surface finish performance in demanding milling applications. At 2.5 inches overall length with a 0.375-inch shank, this tool fits standard collet and end mill holders. It is suited for CNC machining centers and manual mills across production and job shop environments.

This chamfer mill is used in metalworking applications where consistent edge preparation is required before or after part completion. Typical use cases include chamfering drilled holes, countersinking edges prior to assembly, and deburring sharp corners on milled or turned parts. The single-end configuration and 0.153-inch length of cut make it appropriate for light-duty chamfering passes on a variety of workpiece materials. Machinists, toolroom operators, and CNC programmers working in aerospace, automotive, and general machining will find this tool applicable across a broad range of part geometries.

Key Features

• Solid carbide construction provides rigidity and wear resistance compared to HSS alternatives
• APLUS coating extends tool life in ferrous and abrasive materials
• 90-degree included angle with 45-degree side angle for standard chamfer geometry
• Three-flute design balances chip evacuation and surface finish
• Right-hand cutting direction compatible with standard spindle rotation
• 0.375-inch shank fits common collet sizes and end mill holders without adapters

Compatibility

Designed as a direct-fit replacement for standard 0.375-inch shank chamfer mills used in CNC machining centers and manual mills accepting ER or end mill collet toolholders.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet or holder and torque the retention nut according to the toolholder manufacturer specifications. Verify runout with a dial indicator before production use to avoid premature wear or poor chamfer quality.
