Accupro 12183397 Square End Mill 3/16 in 4 Flute Carbide Ticn

Product Description

The ACCUPRO 12183397 is a 4-flute solid carbide square end mill designed for precision milling in metal, composites, and hard materials. It measures 3/16 inches in diameter with a 1-inch length of cut and a 2-1/2-inch overall length, making it suitable for extra-long reach applications where standard-length tools fall short. The TiCN coating reduces friction and improves wear resistance for extended tool life. A 40-degree spiral helix promotes efficient chip evacuation and smooth cutting action. This tool is centercutting, allowing it to plunge directly into a workpiece. It is manufactured from micrograin carbide for consistent edge integrity under demanding conditions.

This end mill is used in CNC machining centers, manual knee mills, and precision benchtop mills across aerospace, automotive, moldmaking, and general metalworking applications. The 3/16-inch shank diameter fits standard collet systems and end mill holders in that bore size. The right-hand cut and right-hand spiral flute configuration suits conventional and climb milling passes on a wide range of ferrous and non-ferrous workpieces. Its extra-long classification makes it a common choice when machining deep slots, pockets, or features that standard-length end mills cannot reach.

Key Features

• Solid micrograin carbide construction for edge sharpness and rigidity
• TiCN finish for reduced friction and improved tool wear resistance
• 4-flute spiral design with 40-degree helix angle for efficient chip evacuation
• Centercutting geometry allows direct plunge entry into material
• Extra-long classification with 1-inch length of cut on a 2-1/2-inch OAL
• Right-hand cut and right-hand flute for standard CNC and manual mill setups

Compatibility

Designed for use in any standard 3/16-inch collet or end mill holder. Compatible with CNC machining centers and manual mills configured for solid carbide tooling in that shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Secure the shank fully within the collet or holder to the recommended grip length and torque the retaining nut per the toolholder manufacturer specifications. Inspect the collet bore and shank for chips or contamination before seating the tool. Never exceed the tool manufacturer recommended speeds and feeds for the workpiece material and coating type.
