Accupro 14735159 Square End Mill 3/8 in 5 Flute Solid Carbide

Product Description

The ACCUPRO 14735159 is a 5-flute solid carbide square end mill designed for high-performance milling in demanding shop environments. It features a 3/8-inch mill diameter, a 1-1/8-inch length of cut, and a 3-inch overall length with a straight cylindrical shank. The 36-degree helix angle promotes efficient chip evacuation and smooth cutting action. Built from micrograin carbide, this tool delivers the rigidity and edge retention required for productive cuts in ferrous and non-ferrous materials. It is a single-end tool with a bright, uncoated finish, suited for applications where base carbide performance is preferred over coated variants.

This end mill is intended for use in CNC machining centers and manual mills where precise, repeatable milling is required. The AL-5 series designation indicates it is engineered for aluminum and light alloy applications, making it a practical choice for aerospace, automotive, and general-purpose shops running aluminum workpieces. The variable index geometry and integrated chipbreaker help reduce chatter and manage chip load at higher feed rates. A licensed machinist or CNC programmer typically selects and installs this tool based on specific material and tolerance requirements.

Key Features

• 5-flute design with variable index geometry for reduced chatter and improved surface finish
• Integrated chipbreaker for controlled chip formation and improved chip evacuation
• 36-degree right-hand helix angle promotes aggressive yet stable cutting
• Micrograin solid carbide construction for extended tool life and edge integrity
• Bright/uncoated finish suitable for aluminum and light alloy milling
• Straight cylindrical shank with tight shank diameter tolerance of -0.0001 to -0.0004 inches for secure tool holding

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills accepting a 3/8-inch straight cylindrical shank end mill in the AL-5 series.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. The machine spindle must be fully stopped and the tool changer or spindle lock engaged before inserting or removing the end mill. Verify that the tool holder bore and collet are clean and free of debris before seating the shank. Confirm runout with a dial indicator after tightening to ensure the shank is within the tolerance required for the application.
