Accupro 14797011 Square End Mill 0.05 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 14797011 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. It features a 0.05-inch cutting diameter and a 0.075-inch length of cut, making it well suited for fine detail work, slotting, and profiling in tight geometries. The two-flute configuration supports efficient chip evacuation, and the AlTiN coating increases surface hardness and heat resistance for extended tool life in ferrous and hardened materials. The stub-length profile adds rigidity, reducing deflection during aggressive cuts. Machinists and tool-and-die professionals working on CNC mills, VMCs, and manual knee mills will find this end mill appropriate for fine-feature work.

This end mill is intended for use in precision machining environments where small-diameter tooling is required. Its 0.05-inch diameter and stub-length geometry make it a practical choice for micro-slot milling, engraving, and detail contouring in ferrous alloys, stainless steel, cast iron, and hardened steels. The AlTiN coating performs well in dry and semi-dry cutting conditions where heat generation is a concern. It is appropriate for both production and prototype machining on CNC equipment capable of high spindle speeds required by small-diameter tooling.

Key Features

• 0.05-inch cutting diameter with a mill diameter tolerance of +0.0000 / -0.0010 inches for accurate sizing
• AlTiN coating provides elevated hardness and thermal resistance for dry and hard-material cutting
• Solid micrograin carbide construction delivers rigidity and wear resistance in demanding cuts
• 2-flute, right-hand spiral flute design with 30-degree helix angle promotes chip flow and surface finish
• Center-cutting capable, allowing plunge entry in addition to peripheral and slot milling
• Stub-length profile minimizes deflection when milling at small diameters

Compatibility

Designed as a standard single-end square end mill compatible with 1/8-inch collets and tool holders on CNC machining centers, vertical mills, and similar equipment requiring small-diameter solid carbide tooling.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and machine power is isolated before changing tooling. Seat the 0.125-inch shank fully and evenly in a clean, undamaged collet or end mill holder, and torque the retention mechanism per the tool holder manufacturer's specification. Verify runout with a dial indicator before beginning production cuts, as runout is especially critical at small diameters to prevent premature tool breakage.
