Accupro 12181928 Square End Mill 3/16 Inch 3 Flute Carbide

Product Description

The ACCUPRO 12181928 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. With a 3/16 inch cutting diameter, a 5/8 inch length of cut, and a 40-degree helix angle, this tool delivers aggressive chip evacuation and clean sidewall finishes in ferrous and non-ferrous materials. The AlTiN coating provides heat resistance and extends tool life in high-speed and dry-cutting conditions. Micrograin carbide construction gives the cutting edges hardness and wear resistance. This end mill is centercutting, allowing plunge entry, and runs in a right-hand cut, right-hand flute configuration. It is sized for use in standard CNC machining centers, vertical mills, and similar equipment.

This end mill suits general-purpose slot milling, profiling, and step milling in job shop, toolroom, and production environments. The regular-length, 2 inch overall length format fits standard tool holders without extended-reach adapters. The 3-flute geometry balances chip clearance with rigidity, making it well suited for aluminum, steel, stainless, and other structural metals. Machinists, CNC operators, and toolroom technicians working in aerospace, automotive, and general fabrication will find this a practical small-diameter option for tight-tolerance work.

Key Features

• Solid micrograin carbide construction for hardness and edge retention
• AlTiN coating for heat resistance and extended tool life in high-speed or dry-cutting conditions
• 40-degree helix angle promotes smooth cutting action and efficient chip evacuation
• Centercutting geometry allows direct plunge entry into workpiece material
• 3-flute spiral design balances chip clearance with tool body rigidity
• Right-hand cut and right-hand flute configuration for standard CNC and manual mill spindles

Compatibility

Designed as a standard 3/16 inch shank end mill for use in collet chucks, end mill holders, and shrink-fit holders accepting 3/16 inch shank tooling on CNC machining centers and manual vertical mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe state before loading or removing the tool. Seat the shank fully within the holder to the minimum insertion depth recommended by the holder manufacturer. Verify runout with a dial indicator after clamping, as micrograin carbide tools are sensitive to excessive runout at small diameters.
