Accupro 14777957 Square End Mill 1/2 in 5 Flute Carbide

Product Description

The ACCUPRO 14777957 is a solid carbide square end mill designed for high-performance milling in demanding machining environments. With a 1/2 inch cutting diameter, 1-1/2 inch length of cut, and 5 flutes in a right-hand spiral configuration, this end mill is built for machinists and tooling professionals who need consistent stock removal and finish quality in a single-end tool. The 36-degree helix angle supports efficient chip evacuation, while the micrograin carbide substrate provides the hardness and wear resistance required for aggressive feeds and speeds in production settings.

The 14777957 is suited for milling operations on machining centers and CNC mills in both job shop and production environments. Its variable index flute spacing reduces chatter and harmonic vibration during extended cuts, and the integrated chipbreaker geometry helps manage chip load in deeper pocketing and slotting passes. The bright, uncoated finish makes it appropriate for a wide range of ferrous and non-ferrous workpiece materials where coating interaction is a concern.

Key Features

• 5-flute design with variable index spacing reduces vibration and chatter
• Chipbreaker geometry assists chip management in pocketing and slotting applications
• 36-degree right-hand helix angle promotes efficient chip evacuation
• Micrograin solid carbide substrate delivers hardness and edge retention
• Straight-cylindrical shank fits standard ER and side-lock toolholders
• Bright/uncoated finish compatible with dry or flood coolant cutting strategies

Compatibility

Designed as an OEM-style replacement and standard production end mill for CNC machining centers and knee mills accepting a 1/2 inch straight-cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Secure the shank fully within the toolholder to the minimum insertion depth recommended for the holder type, and verify runout with a dial indicator before cutting. Power down and lock out the spindle before changing tooling. Do not exceed the tool manufacturer-recommended feed and speed parameters for the workpiece material.
