Promax 109-01614 Square End Mill 1/4 in 3 Flute Solid Carbide

Product Description

The PROMAX 109-01614 is a solid carbide square end mill designed for precision milling in demanding machining environments. This single-end tool features a 1/4 inch cutting diameter, a 3/4 inch length of cut, and a 2-1/2 inch overall length with a 1/4 inch shank. Built from micrograin solid carbide and finished with an AlTiN (aluminum titanium nitride) coating, it delivers extended tool life in high-heat applications. The 35-degree spiral flute geometry and three-flute configuration promote efficient chip evacuation and smooth cutting action on ferrous and non-ferrous materials.

This end mill is suited for slotting, profiling, and peripheral milling operations on machining centers and CNC mills. Its centercutting capability allows direct plunge entry without a pre-drilled hole. The right-hand cut and right-hand flute orientation make it compatible with standard spindle configurations. Series 109 tools from PROMAX are commonly used in job shops and production environments where dimensional accuracy and surface finish are critical requirements.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• AlTiN coating for extended tool life in elevated-temperature cutting conditions
• 35-degree helix angle promotes smooth cutting action and chip flow
• Centercutting design enables direct plunge entry into workpiece material
• Three-flute configuration balances material removal rate with surface finish quality
• Tight diameter tolerances: +0.000/-0.002 inches on mill diameter, -0.0001/-0.0004 inches on shank diameter

Compatibility

Designed for use with standard 1/4 inch collet chucks and end mill holders on CNC machining centers and manual knee mills. Fits ER16 and ER20 collet systems that accept 1/4 inch shank tooling.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank fully into the collet or holder and torque the drawbar or nut to the tool holder manufacturer's specification. Verify runout with a dial indicator after installation before commencing a cut.
