Accupro 14788563 Square End Mill 4 Flute 1/4 Inch Carbide

Product Description

The ACCUPRO 14788563 is a 4-flute, solid carbide square end mill designed for general-purpose milling operations in metal, composites, and engineering plastics. The 1/4-inch mill diameter with a matching 1/4-inch cylindrical shank seats securely in standard ER and set-screw toolholders. A 1.25-inch length of cut provides sufficient reach for most shoulder, slot, and peripheral milling applications. Centercutting geometry allows plunge entry directly into the workpiece without a pre-drilled pilot hole. Helical flutes promote chip evacuation and reduce cutting forces across a wide range of materials and feed rates.

This end mill is suited for CNC machining centers, knee mills, and manual milling machines used in job shops, maintenance facilities, and production environments. At 0.25 inches in diameter, it is a commonly specified size for slotting, contouring, and pocketing cuts in aluminum, steel, stainless, and similar workpiece materials. The 3-inch overall length keeps deflection manageable while still clearing common fixturing heights. Licensed machinists, tool-and-die makers, and maintenance mechanics are the typical end users.

Key Features

• Solid carbide construction for rigidity and wear resistance at elevated cutting speeds
• 4-flute helical geometry balances material removal rate with surface finish quality
• Centercutting design permits direct plunge milling without a pilot hole
• 1/4-inch mill diameter and 1/4-inch cylindrical shank fit standard collet and set-screw toolholders
• 1.25-inch length of cut suitable for shoulder milling, slotting, and pocket operations
• 3-inch overall length minimizes overhang deflection in typical setups

Compatibility

Designed as a standard replacement or stock solid carbide square end mill for any milling machine or machining center equipped with a 1/4-inch collet, ER collet chuck, or set-screw toolholder accepting a cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with proper toolholder torque procedures and machine lockout requirements. Ensure the machine spindle is fully stopped and the control is in a safe state before changing tooling. Inspect the shank and collet bore for chips or contamination before seating the tool. Follow the machine manufacturer and toolholder manufacturer guidelines for pull-out force and runout tolerances when setting cutting depth and feed parameters.
