M.a. Ford. 27818730B Square End Mill 3/16 in 5 Flute Carbide

Product Description

The M.A. FORD. 27818730B is a 5-flute solid carbide square end mill designed for precision milling operations in metal-cutting applications. It carries a 3/16-inch cutting diameter, a 3/4-inch length of cut, and a 2-1/2-inch overall length. The tool features a 40-degree helix angle, variable index flute spacing, and an AlCrN (aluminum chromium nitride) coating for elevated heat resistance and extended tool life at high cutting speeds. Micrograin carbide substrate adds edge strength and wear resistance. This is a single-end, right-hand cut, right-hand flute tool suited for machinists working in production or job-shop environments.

This end mill is well matched to finishing and semi-finishing passes in ferrous and hardened materials where heat generation and tool deflection are primary concerns. The 40-degree helix promotes smooth chip evacuation and reduces cutting forces, making it effective in tight-tolerance work. The 3/16-inch shank diameter matches the cutting diameter for direct collet or end mill holder mounting. It is sized for CNC machining centers and manual knee mills running small-diameter work, including die and mold details, slots, and peripheral profiles.

Key Features

• 5-flute geometry increases feed rate capability compared to standard 4-flute designs in finishing applications
• 40-degree helix angle promotes efficient chip evacuation and reduces radial cutting forces
• Variable index flute spacing reduces harmonic vibration during cutting
• AlCrN coating provides high oxidation resistance and thermal hardness for dry or high-speed machining
• Micrograin solid carbide substrate delivers superior edge retention and rigidity at small diameters
• Center-cutting capable, allowing direct plunge entry

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for standard 3/16-inch collets, end mill holders, and shrink-fit tooling used in CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholding torque and runout specifications. Ensure the spindle and toolholder are clean and free of chips before seating the shank. Verify collet or holder is rated for the shank diameter before tightening. Always bring the spindle to a complete stop before changing or inspecting the tool.
