Accupro 12181712 Square End Mill 1 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 12181712 is a solid carbide square end mill designed for precision milling in demanding metal-cutting applications. Built from micrograin carbide and finished with an AlTiN (aluminum titanium nitride) coating, it handles high-heat cutting environments where tool life and dimensional accuracy matter. The 2-flute, spiral configuration with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. At 1 inch in diameter with a 2.25 inch length of cut and 5 inch overall length, this is a long-reach end mill suited for deeper pockets and full-slot milling passes where standard-length tools fall short. Centercutting geometry allows plunge entry directly into workpiece material.

This end mill fits standard CNC machining centers and manual mills equipped with a 1 inch toolholder or collet. Its long length-of-cut range makes it well suited for deep-pocket profiling, slotting, and side milling in ferrous and non-ferrous materials. The AlTiN finish supports dry or near-dry cutting at elevated spindle speeds, making it a practical choice for production shops running steel, stainless, and hardened alloys. Right-hand cut and right-hand flute geometry follow conventional milling configurations found on the majority of vertical machining centers.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• AlTiN finish supports high-temperature, high-speed cutting
• 40-degree helix angle with spiral flutes for efficient chip evacuation
• Centercutting design allows direct plunge entry into material
• Long length-of-cut category (2 inches and above) for deep-pocket applications
• Right-hand cut, right-hand flute — standard CNC orientation

Compatibility

Designed for use in CNC machining centers and manual mills accepting a 1 inch straight shank via ER collet, end mill holder, or equivalent toolholding system.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and machine is in an estop or lockout state before inserting or removing the end mill. Seat the shank to the minimum insertion depth recommended by the toolholder manufacturer to maintain concentricity and avoid pullout under cutting loads. Verify runout with a dial indicator after toolsetting before beginning a production cut.
