Accupro 12181457 Square End Mill 0.4724 in 2 Flute Carbide

Product Description

The ACCUPRO 12181457 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. With a 0.4724-inch mill diameter and a 0.9843-inch length of cut, this single-end tool delivers consistent material removal across a range of ferrous and non-ferrous applications. The 40-degree helix angle and spiral flute geometry promote efficient chip evacuation and reduced cutting forces. An AlTiN finish improves thermal resistance and extends tool life in high-temperature cutting conditions. This end mill is handled and installed by machinists and tool-and-die professionals working on CNC mills and manual milling machines.

This end mill suits general-purpose profiling, slotting, and peripheral milling in a shop or production environment. The centercutting design allows plunge cuts as well as conventional side milling. The regular length classification makes it appropriate for standard reach applications where rigidity is a priority. Right-hand cut and right-hand flute orientation match the most common CNC and manual spindle configurations.

Key Features

• Solid carbide micrograin construction for hardness and wear resistance
• AlTiN coating for elevated thermal performance in dry or semi-dry cutting
• 40-degree helix angle with spiral flute for effective chip evacuation
• Centercutting capable — supports plunge entry without a pre-drilled hole
• Right-hand cut, right-hand flute — compatible with standard spindle rotation
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent fit and finish

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for standard milling collets and end mill holders accepting a 12.00 mm (0.4724-inch) shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and power is isolated before changing tooling. Seat the shank fully into the collet or tool holder and torque the retention mechanism to the holder manufacturer specification. Verify runout with a dial indicator before initiating a cut, as excessive runout accelerates edge wear on carbide tooling.
