Helical Solutions 83808 Chamfer Mill 0.25in 4 Flute Carbide

Product Description

The HELICAL SOLUTIONS 83808 is a single-end chamfer mill designed for deburring, chamfering, and edge-breaking operations on metal workpieces. Built from solid carbide and finished with an Aplus coating, this tool delivers consistent performance in high-demand milling environments. The 90-degree included angle and 4-flute helical design provide clean, precise cuts with reduced chatter. At 0.25 inches in diameter with a matching 0.25-inch shank, it is sized for compact setups and tight geometries. Machinists and CNC operators in job shops, production facilities, and toolrooms rely on this style of chamfer mill for repeatable edge preparation and countersinking work.

The 83808 is suited for chamfering and deburring applications on ferrous and non-ferrous metals where a 90-degree edge profile is required. The right-hand cutting direction and 4-flute configuration support efficient chip evacuation and smooth surface finishes. With an overall length of 2.5 inches and a 0.12-inch length of cut, this tool fits standard CNC machining centers and manual milling machines running standard 0.25-inch collets or end mill holders. It is a strong fit for production runs and prototype work alike where consistent chamfer geometry is critical.

Key Features

• Solid carbide construction for rigidity and wear resistance in metal-cutting applications
• Aplus coating reduces friction and extends tool life in high-speed operations
• 90-degree included angle for standard chamfer and countersink profiles
• 4-flute helical design promotes smooth chip flow and reduces surface chatter
• Right-hand cutting direction compatible with conventional CNC spindle rotation
• Single-end configuration simplifies tool changes and holder setup

Compatibility

Designed as an OEM-style replacement or direct-use chamfer mill for machining centers and manual mills accepting a 0.25-inch shank in standard collet or end mill holder systems.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully powered down and the machine is in a safe state before loading or unloading the tool. Secure the shank fully within the collet or holder to the recommended engagement depth per the toolholder manufacturer. Verify spindle speed and feed rate settings against recommended parameters for solid carbide tooling before initiating a cut.
