Accupro 12176970 Square End Mill 1/8 in 4 Flute Carbide

Product Description

The ACCUPRO 12176970 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 0.1250-inch mill diameter, a 0.5000-inch length of cut, and a 1.5000-inch overall length, this end mill handles slotting, profiling, and peripheral milling with consistent accuracy. The 40-degree helix angle and spiral flute geometry promote efficient chip evacuation and smooth cutting action. The micrograin carbide substrate delivers hardness and wear resistance suited for demanding materials. Right-hand cut with left-hand flute orientation, this tool is centercutting and capable of plunge entry. It ships individually and is uncoated.

This end mill fits standard CNC machining centers, manual mills, and high-speed spindle applications where a 1/8-inch diameter tool is required. The 1/8-inch shank diameter seats directly into collets and tool holders sized for that bore. Typical applications include fine-feature milling on aluminum, brass, steel, and similar materials in job shops, tool rooms, and production environments. The compact 1.5000-inch overall length makes it well suited for low-clearance setups and shallow-reach applications.

Key Features

• Solid micrograin carbide construction for hardness and edge retention
• 40-degree helix angle promotes efficient chip flow and smooth cutting action
• Centercutting design allows plunge milling entry
• Right-hand cut, left-hand flute configuration for climb or conventional milling
• Spiral flute geometry reduces chatter in fine-diameter applications
• Mill diameter tolerance of +0.000 / -0.002 inches for dimensional accuracy

Compatibility

Designed as an OEM-style replacement or direct fitment for CNC and manual milling setups requiring a 1/8-inch diameter, 4-flute square end mill with a 1/8-inch shank in standard ER or precision collet tool holders.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and locked out before tool changes. Seat the shank fully into the collet or tool holder and torque the retention nut to the tool holder manufacturer specification. Verify runout with a dial indicator before beginning a cut, particularly at small diameters where deflection tolerance is tight.
