Accupro 14735166 Square End Mill 5/8 in 5 Flute Carbide

Product Description

The ACCUPRO 14735166 is a solid carbide square end mill designed for high-performance material removal in milling operations. Built to AL-5 Series specifications, it features a 5/8-inch cutting diameter, a 1-7/8-inch length of cut, and a 36-degree helix angle that promotes efficient chip evacuation and reduced cutting forces. The micrograin carbide construction delivers hardness and wear resistance suited to demanding cutting applications. This end mill is single-end, right-hand cutting, and carries a variable index geometry with a chipbreaker profile, making it a practical choice for machinists running aluminum and non-ferrous materials at elevated feed rates.

The 14735166 is intended for use in CNC milling operations on machining centers and manual knee mills where a straight-cylindrical shank is standard. The 5-flute configuration and 36-degree helix suit high-speed finishing and semi-finishing passes. With a 4-inch overall length and a 5/8-inch straight shank, it fits standard ER and side-lock tool holders common in production and job-shop environments. The bright/uncoated finish makes it a reliable option where coated tooling is unnecessary or where regrinding is planned.

Key Features

• Solid micrograin carbide construction for hardness and wear resistance
• 5 flutes with variable index geometry for reduced chatter and vibration
• Chipbreaker profile aids chip control during deep-slot and shoulder milling
• 36-degree right-hand spiral helix promotes efficient chip evacuation
• Bright/uncoated finish suitable for non-ferrous and aluminum applications
• Single-end design; not center-cutting — requires a pilot hole or side entry

Compatibility

Designed as a direct-fit replacement or production-run solid carbide end mill for standard 5/8-inch straight-cylindrical tool holders used in CNC and manual milling applications.

Installation Notes

Installation should be performed by a qualified machinist familiar with tool-holder torque and runout specifications for carbide end mills. Ensure the tool holder bore and retention mechanism are clean and free of chips before seating the shank. Confirm tool runout with a dial indicator before initiating a cut, as excessive runout accelerates carbide wear and can cause tool failure. Because this end mill is not center-cutting, it must be entered from the side or into a pre-drilled hole.
