Accupro 12277019 Square End Mill 0.01in 4 Flute Carbide

Product Description

The ACCUPRO 12277019 is a solid carbide square end mill designed for precision milling in demanding machining applications. With a 0.01 inch cutting diameter and a 0.015 inch length of cut, this tool is built for micro-milling work where dimensional accuracy is critical. The four-flute, right-hand spiral configuration provides efficient chip evacuation and a stable cut. Micrograin carbide construction delivers the hardness and wear resistance required for tight-tolerance work in ferrous and non-ferrous materials. The bright, uncoated finish makes it suitable for applications where coating adhesion or heat interaction is a concern.

This end mill is used in CNC machining centers and manual mills for micro-detail work, slotting, and profiling in tooling, mold, and die applications. Its 1/8 inch shank diameter fits standard collets and tool holders common in precision machine shops. The 1.5 inch overall length keeps deflection low, which is especially important at this diameter. Single-end design means the tool is replaced when worn rather than indexed.

Key Features

• 0.01 inch cutting diameter for micro-milling and fine-detail work
• Solid micrograin carbide construction for hardness and edge retention
• 4-flute, right-hand spiral flute design for smooth cutting action
• 30-degree helix angle balances chip flow and cutting stability
• Centercutting capable — can plunge directly into material
• Bright/uncoated finish suitable for a broad range of workpiece materials

Compatibility

Designed for use in CNC machining centers and precision manual mills accepting a 1/8 inch collet or end mill holder. Suitable for micro-milling operations in tool steels, aluminum, and similar machinable materials where tight diameter tolerances are required.

Installation Notes

Installation should be performed by a qualified machinist following standard tooling procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the 1/8 inch shank fully into the collet or tool holder and torque the retention system according to the tool holder manufacturer specifications. At 0.01 inch diameter, this tool is extremely fragile — handle with care, avoid side-loading during setup, and verify runout before cutting.
