Accupro 12181562 Square End Mill 7/8 in 2 Flute Carbide

Product Description

The ACCUPRO 12181562 is a solid carbide square end mill designed for precision milling operations in metal and alloy workpieces. With a 7/8-inch mill diameter, a 1-3/4-inch length of cut, and a 4-inch overall length, this tool delivers consistent material removal in a standard 2-flute configuration. The AlTiN coating increases surface hardness and heat resistance, extending tool life during high-speed or dry cutting. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces. Right-hand cut and right-hand flute geometry is standard. Micrograin solid carbide construction provides rigidity and wear resistance across a range of workpiece materials.

This end mill is suited for slot milling, peripheral milling, and plunge cutting in ferrous and non-ferrous metals. The centercutting design allows direct plunge entry without a pre-drilled pilot hole, making it practical for die and mold work, fixture machining, and general CNC milling. The spiral flute geometry and AlTiN finish make it a capable choice for production environments where tool life and surface finish matter. It is sold individually and is compatible with standard collet chucks, end mill holders, and milling machine spindles accepting a 7/8-inch shank.

Key Features

• 7/8-inch mill diameter with 7/8-inch shank for direct fit in standard holders
• AlTiN finish for improved heat resistance and extended tool life
• 40-degree helix angle for efficient chip evacuation
• Centercutting geometry allows direct plunge entry
• Micrograin solid carbide blank for rigidity and wear resistance
• Right-hand cut, right-hand flute spiral configuration

Compatibility

Designed for use in standard end mill holders, collet chucks, and CNC or manual milling machine spindles accepting a 7/8-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill. Seat the shank fully into the holder to the recommended minimum engagement depth and torque the retention hardware per the holder manufacturer specifications. Verify runout with a dial indicator before beginning a production cut.
