Accupro 12182156 Square End Mill 3/32 in Solid Carbide

Product Description

The ACCUPRO 12182156 is a solid carbide square end mill designed for precision milling in metal fabrication, tool-and-die, and general machining applications. It measures 0.0938 inches (3/32 inch) in diameter with a 3/16 inch length of cut and a 1/8 inch shank diameter, making it well suited for close-tolerance work in tight spaces. The AlTiN coating improves heat resistance and extends tool life during dry or high-speed cutting. With three right-hand spiral flutes and a 30-degree helix angle, this end mill provides efficient chip evacuation and a smooth cutting action. Overall length is 1.5 inches, classifying it as a stub-length tool.

This end mill is used in CNC milling operations where small-diameter, high-precision cutting is required. The stub-length profile increases rigidity and reduces deflection, making it a reliable choice for slotting, profiling, and pocket milling in ferrous and non-ferrous materials. Its centercutting capability allows direct plunge entry without a pre-drilled hole. Machinists and tool-and-die professionals working with hardened steels, stainless, and similar alloys will find the AlTiN finish particularly effective at maintaining edge integrity under elevated temperatures.

Key Features

• Solid carbide micrograin construction for hardness and wear resistance
• AlTiN coating enhances heat resistance for dry and high-speed cutting
• 3 right-hand spiral flutes with 30-degree helix angle for efficient chip removal
• Centercutting design allows direct plunge milling
• Stub-length body increases rigidity and reduces tool deflection
• Right-hand cut and right-hand flute configuration for standard CNC spindle use

Compatibility

Designed as a standard shank solid carbide square end mill suitable for CNC machining centers and manual mills accepting a 1/8 inch shank diameter collet or toolholder.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the spindle is fully stopped and locked before inserting or removing the tool from the collet or chuck. Verify collet size matches the 1/8 inch shank diameter and that runout is within acceptable tolerance before cutting. Follow machine manufacturer guidelines for speed and feed settings appropriate to the workpiece material and tool diameter.
