Promax 134-02430 Chamfer Mill Solid Carbide 3/8 Inch Shank

Product Description

The PROMAX 134-02430 is a 2-flute solid carbide chamfer mill designed for chamfering, countersinking, and spotting operations on metal workpieces. It features a 3/8-inch cutter head diameter and a matching 3/8-inch shank diameter, with an overall length of 2.5 inches. The bright/uncoated finish keeps the carbide substrate exposed for general-purpose cutting. Right-hand cutting direction makes it compatible with standard CNC and manual milling setups. Machinists and tool-and-die professionals reach for this style of end mill when they need clean chamfer geometry without secondary deburring.

This chamfer mill suits light to medium-duty milling centers, knee mills, and CNC machining centers in both job shop and production environments. The 3/8-inch shank fits standard ER collet chucks and end mill holders commonly found in those setups. Typical applications include edge preparation before welding, countersink generation for fastener seating, and center-spotting prior to drilling on ferrous and non-ferrous materials. The solid carbide construction holds geometry longer than high-speed steel alternatives under consistent feed and speed conditions.

Key Features

• 2-flute geometry for efficient chip evacuation during chamfering and spotting
• Solid carbide construction for rigidity and edge retention
• Bright/uncoated finish suitable for general-purpose ferrous and non-ferrous applications
• Right-hand cutting direction compatible with standard spindle rotation
• 3/8-inch shank fits common ER collet and end mill holder tooling
• Multi-application use: chamfering, countersinking, and spotting in a single tool

Compatibility

Designed as an OEM-style replacement or standard tooling option for milling machines and machining centers accepting a 3/8-inch shank diameter in ER collet chucks or end mill holders.

Installation Notes

Installation is performed by a machinist or tooling technician. Ensure the spindle is fully stopped and locked out 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 beginning a cut, as excessive runout accelerates edge wear on carbide tooling.
