Helical Solutions 83850 Chamfer Mill 1/4 in 2 Flute Carbide

Product Description

The HELICAL SOLUTIONS 83850 is a solid carbide chamfer mill designed for deburring, chamfering, and edge-breaking operations on a wide range of materials. With a 0.25 inch cutter head diameter and a 90-degree included angle, this single-end tool produces clean, consistent chamfers in one pass. The Zplus coating improves surface lubricity and wear resistance, making the tool well-suited for ferrous and non-ferrous applications. At 2.5 inches overall length with a 0.25 inch shank diameter, the 83850 is a compact, balanced tool that fits standard collet chucks and toolholders. Machinists, tool and die shops, and CNC operators are the primary users.

This chamfer mill is used in precision machining environments including job shops, aerospace component fabrication, mold and die work, and general CNC milling operations. It is suited for chamfering drilled holes, deburring part edges, and countersinking light features on steel, aluminum, stainless, and similar machinable alloys. The right-hand cutting direction and two-flute geometry provide efficient chip evacuation in moderate-depth chamfering cuts on both vertical and horizontal machining centers.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding machining environments
• Zplus coating reduces friction and extends tool life on ferrous and non-ferrous materials
• 90-degree included angle for standard chamfer and deburring profiles
• 0.12 inch length of cut accommodates typical edge-break and chamfer depths
• Right-hand cutting direction compatible with standard CNC spindle rotation
• Compact 2.5 inch OAL with 0.25 inch shank fits most standard ER collet chucks

Compatibility

Designed as an OEM-style replacement chamfer mill for use in standard 0.25 inch collet chucks and toolholders on CNC machining centers and manual mills.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before changing tooling. Seat the shank fully into the collet and torque the collet nut to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning production cuts.
