Accupro 12182761 Square End Mill 3/16 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12182761 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. It features a 3/16 inch cutting diameter, a 3/8 inch length of cut, and a 2 inch overall length in a stub-length configuration. The 4-flute, spiral-flute geometry with a 40-degree helix angle promotes efficient chip evacuation and smooth surface finishes. A TiCN (Titanium Carbonitride) coating increases surface hardness and reduces friction, extending tool life in ferrous and non-ferrous materials. The micrograin carbide substrate provides the rigidity and edge retention needed for demanding cuts.

This end mill is suited for slot milling, peripheral milling, and plunge cutting in CNC machining centers and manual milling machines. The centercutting design allows direct plunge entry into the workpiece without pre-drilling. Right-hand cut and right-hand flute orientation are standard for conventional milling setups. The stub-length body minimizes deflection, making it a reliable choice for tight-tolerance work in tool rooms, job shops, and production environments.

Key Features

• Solid micrograin carbide construction for superior edge retention and rigidity
• TiCN coating for increased surface hardness and extended tool life
• 40-degree helix angle with spiral flute geometry for efficient chip evacuation
• Centercutting capable — supports direct plunge entry without pre-drilling
• Stub-length body reduces deflection for tight-tolerance milling
• Right-hand cut, right-hand flute — standard orientation for conventional setups

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 3/16 inch collets and tool holders used in CNC machining centers and manual milling machines requiring a 3/16 inch shank diameter end mill.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully powered down and the machine is in a safe state before changing tooling. Secure the shank firmly in a properly sized collet or end mill holder, observing the minimum clamping engagement length recommended by your tool holder manufacturer. Verify runout with a dial indicator before initiating a cut to protect both the tool and the workpiece.
