Helical Solutions 06138 Chamfer Mill 1/4 in 4 Flute Carbide

Product Description

The HELICAL SOLUTIONS 06138 is a solid carbide chamfer mill designed for precise chamfering and deburring operations on metallic workpieces. Built with four flutes and a 90-degree included angle, it produces clean, consistent chamfer edges in a single pass. The 0.2500 inch cutter head diameter and matching 0.2500 inch shank diameter allow direct chuck mounting without reducers. An Aplus coating improves lubricity and heat resistance, extending tool life in ferrous and non-ferrous cutting applications. Overall length is 2.5 inches with a 0.1250 inch length of cut. Machinists and CNC operators working in job shops, toolrooms, and production environments rely on this geometry for edge preparation and countersinking tasks.

This chamfer mill is suited for use on CNC machining centers and manual mills where controlled edge breaking and chamfering are required. Right-hand cutting direction makes it compatible with standard spindle rotation. The single-end configuration and compact cutting length of 0.1250 inches work well for light chamfering passes on steel, aluminum, and similar materials. It is a practical choice for toolrooms and production shops that require consistent chamfer quality across repeat operations.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cutting conditions
• Aplus coating reduces friction and heat buildup, extending tool life
• 90-degree included angle for standard chamfer and deburring applications
• Four flutes for improved chip evacuation and surface finish
• Right-hand cutting direction compatible with standard CNC and manual mill spindles
• Matched shank and cutter diameter of 0.2500 inches simplifies toolholder selection

Compatibility

Designed as an OEM-style solid carbide chamfer mill for use in standard 1/4 inch collets, end mill holders, or equivalent toolholding systems on CNC machining centers and manual mills.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Secure the shank fully in a 1/4 inch collet or end mill holder and verify runout before cutting. Power down the spindle completely before changing or inspecting tooling. Follow shop-specific speeds and feeds guidelines for the workpiece material and coating type.
