Accupro 14788423 Square End Mill 3 Flute 1/4 Inch Carbide

Product Description

The ACCUPRO 14788423 is a solid carbide square end mill designed for precision milling operations in metal, composite, and engineering plastic workpieces. With a 1/4 inch (0.2500 inch) mill diameter and three helical flutes, it delivers efficient chip evacuation and a smooth finish in a wide range of machining applications. The centercutting geometry allows direct plunge cuts without pre-drilling. A helix angle of 38 to 42 degrees promotes aggressive material removal while reducing chatter. This end mill is suited for CNC machining centers and manual mills operated by machinists and toolmakers in job shop and production environments.

The 14788423 is used in milling slots, pockets, profiles, and contours in ferrous and non-ferrous materials. The 1-1/8 inch (1.1250 inch) length of cut accommodates moderate-depth passes without excessive tool deflection. The cylindrical shank measures 1/4 inch in diameter, fitting standard ER collets and end mill holders. With an overall length of 3 inches, the tool balances reach and rigidity for typical workholding setups. It is well suited to light-to-medium duty roughing and finishing passes in a production or prototype machining environment.

Key Features

• Solid carbide construction provides hardness and wear resistance superior to high-speed steel
• Three helical flutes with a 38 to 42 degree helix angle for efficient chip flow and reduced cutting forces
• Centercutting design enables direct plunge entry into the workpiece
• 1-1/8 inch length of cut supports slot milling and pocket work at moderate depths
• Cylindrical 1/4 inch shank compatible with standard collet and end mill holder systems
• No chipbreaker geometry for clean, consistent finishes in finishing pass applications

Compatibility

Designed as an OEM-style solid carbide end mill for use in CNC machining centers and manual milling machines equipped with 1/4 inch collet or end mill holder tooling.

Installation Notes

Installation should be performed by a qualified machinist following standard tool-change procedures for the machine in use. Always power down and lock out the spindle before seating or removing the tool from the holder. Ensure the shank is clean and fully seated to the recommended engagement depth in the collet or holder before tightening. Inspect the cutting edges for chipping before each use and replace the tool if edge integrity is compromised.
