Accupro 12181787 Square End Mill 9/32 in 2 Flute Carbide

Product Description

The ACCUPRO 12181787 is a solid carbide square end mill designed for precise milling operations in ferrous and non-ferrous materials. It features a 9/32 inch (0.2813 inch) cutting diameter, a 1-1/4 inch length of cut, and a 3 inch overall length, classifying it as an extra-long configuration. The AlTiN finish provides heat and oxidation resistance, extending tool life in high-speed and dry-cutting applications. The 40-degree helix spiral flute geometry promotes efficient chip evacuation and smooth cutting action. This end mill is intended for use by machinists and tooling professionals in CNC machining centers, manual mills, and production environments.

This end mill is suited for slotting, profiling, and contouring operations where an extra-long reach is required. The centercutting design allows plunge cutting in addition to peripheral and slot milling. The right-hand cut and right-hand flute configuration is standard for conventional CNC and manual milling setups. The micrograin carbide grade provides a balance of hardness and toughness appropriate for precision work in steel, stainless, cast iron, and aluminum alloys.

Key Features

• 9/32 inch cutting diameter with a tolerance of +0.000 / -0.002 inches for precise fitment
• 1-1/4 inch length of cut in an extra-long overall length of 3 inches
• Solid micrograin carbide construction for hardness and edge retention
• AlTiN coating for elevated heat resistance and extended tool life in dry or high-speed cutting
• 40-degree helix spiral flute promotes chip evacuation and reduces cutting forces
• Centercutting geometry allows direct plunge entry into workpiece material

Compatibility

Designed as a standard replacement or production end mill for CNC machining centers and manual milling machines accepting a 5/16 inch shank diameter collet or tool holder.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the milling machine spindle is fully stopped and locked out before changing tooling. Seat the 5/16 inch shank fully into a clean, undamaged collet or end mill holder and torque the retention hardware to the tool holder manufacturer specification. Inspect the cutting edges for chips or wear before each use, and verify runout with a dial indicator when precision tolerances are required.
