Accupro 12182181 Square End Mill 3/8 in 3 Flute Carbide

Product Description

The ACCUPRO 12182181 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. It features a 3/8-inch diameter with a 5/8-inch length of cut and a stub-length overall length of 2 inches, making it well-suited for operations where rigidity and reduced deflection are priorities. The micrograin carbide construction provides hardness and edge retention across a wide range of workpiece materials. With a 40-degree helix angle and spiral flute geometry, this tool promotes efficient chip evacuation and smooth cutting action. It is installed and operated by machinists and CNC operators in production and job-shop environments.

This end mill is configured as a single-end, centercutting tool with right-hand cut and right-hand flute direction, allowing it to plunge as well as perform peripheral and slot milling. The stub-length format provides added stiffness relative to longer reach variants, making it a practical choice for shallow-pocket and slot-milling operations on milling machines and CNC machining centers. It ships individually and carries a minimum order quantity of one unit.

Key Features

• Solid micrograin carbide construction for hardness and edge retention
• 40-degree helix angle promotes efficient chip evacuation
• Centercutting design allows direct plunge entry into workpiece
• Right-hand cut and right-hand flute direction for standard spindle rotation
• Stub-length format maximizes rigidity and minimizes deflection
• Uncoated finish suitable for use across a variety of workpiece materials

Compatibility

Designed as a direct-fit replacement or standard tooling selection for 3/8-inch collet or end mill holder setups on conventional and CNC vertical milling machines.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout tolerance. Ensure the spindle is fully stopped and the machine is in a safe state before inserting or removing the end mill. Use a properly sized collet or end mill holder to match the 3/8-inch shank diameter. Verify tool projection and overhang to maintain the rigidity benefits of the stub-length design.
