Promax 117-01614 Roughing Finishing End Mill 1/4 in

Product Description

The PROMAX 117-01614 is a solid carbide roughing finishing end mill designed for high-efficiency material removal with a refined surface finish in a single operation. The 1/4 inch diameter, 3-flute design features a 0.02 inch corner radius end geometry and a chipbreaker profile that reduces cutting forces and manages chip evacuation. An AlTiN coating provides thermal resistance and extended tool life in ferrous and high-temp alloy applications. The 35-degree helix angle promotes smooth cutting action and reduces vibration. This tool is suited for machinists and toolroom professionals working on CNC milling centers and manual mills.

This end mill is used in precision machining environments where a single tool needs to handle both roughing passes and semi-finishing work. It is particularly well suited for milling steel, stainless steel, and hardened alloys in production or job-shop settings. The chipbreaker geometry makes it effective in deeper axial cuts where chip control is critical. The straight-cylindrical shank and standard length profile allow direct installation into standard collet chucks and end mill holders without modification.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• AlTiN coating for high-temperature performance and extended tool life
• Chipbreaker profile reduces cutting forces and improves chip control
• 0.02 inch corner radius reduces stress concentration at the cutting edge
• 35-degree helix angle promotes smooth chip evacuation and reduced vibration
• Right-hand cut, right-hand flute, single-end design for standard CNC and manual milling setups

Compatibility

Designed as an OEM-style replacement or direct-fit tooling solution for standard 1/4 inch straight-cylindrical shank collet chucks and end mill holders on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholder torque and runout specifications. Ensure the spindle is fully stopped and the machine is in a safe lockout state before changing tooling. Verify shank seating depth and runout with a dial indicator before initiating cuts. Do not exceed the tool's rated depth of cut or feed rate for the workpiece material.
