Accupro 12178581 Square End Mill 3/16 in 3 Flute Carbide

Product Description

The ACCUPRO 12178581 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. Built from micrograin carbide, this single-end tool features a 3/16 inch cutting diameter with a stub-length configuration and a 40-degree helix angle for efficient chip evacuation. The three-flute, right-hand spiral geometry supports aggressive feed rates while maintaining a clean surface finish. Centercutting capability allows plunge entry directly into workpiece material without a pre-drilled pilot hole. This end mill is sold individually and is suited for use in CNC machining centers and manual mills.

This end mill is used in general-purpose slot milling, profiling, and contouring operations across ferrous and non-ferrous materials. The stub length of cut at 3/8 inch and a 2 inch overall length provide rigidity in tight-tolerance work where deflection must be minimized. The uncoated micrograin carbide construction is appropriate for dry or flood-cooled cutting environments where coatings are not required by the application or material.

Key Features

• Solid micrograin carbide construction for hardness and wear resistance
• 40-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Centercutting design allows direct plunge milling without a pilot hole
• Right-hand cut and right-hand flute orientation for standard spindle direction
• Stub length-of-cut range provides added rigidity and reduced deflection
• Uncoated finish suitable for a range of general milling materials

Compatibility

Designed as an OEM-style replacement or standard tooling selection for 3/16 inch shank collets and tool holders used in CNC machining centers and manual vertical mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully within the collet or end mill holder and verify runout before engaging the cut. Ensure the machine spindle is stopped and the control is in a safe state before tool changes. Consult the machine tool manufacturer guidelines and applicable shop safety standards when setting speeds and feeds for the workpiece material.
