Accupro 12181914 Square End Mill 3/16 in 3 Flute Carbide

Product Description

The ACCUPRO 12181914 is a solid carbide square end mill designed for precision milling of ferrous and non-ferrous materials in machine shop and manufacturing environments. The 3-flute, single-end geometry with a 40-degree helix angle delivers a balance between chip evacuation and surface finish. At 3/16 inch in diameter with a 5/8 inch length of cut, this tool suits tight-tolerance slotting, profiling, and plunge cuts in small-feature work. Centercutting capability allows direct plunge entry without a pre-drilled hole. The micrograin carbide substrate provides edge retention and wear resistance in demanding cutting applications.

This end mill fits standard CNC machining centers, knee mills, and manual mills equipped with a 3/16 inch collet or ER collet system. It is suited for finish milling of aluminum, brass, plastics, and soft steels where a compact, short-reach tool is required. The right-hand cut and right-hand spiral flute configuration is compatible with conventional spindle rotation on standard vertical milling setups. The regular length designation and 2 inch overall length make it a practical choice for general-purpose work where extended reach is not needed.

Key Features

• Solid micrograin carbide construction for edge retention and dimensional stability
• 3 flutes with 40-degree helix angle for efficient chip flow and smooth finish
• Centercutting design allows direct plunge entry
• Right-hand cut, right-hand flute configuration for standard spindle use
• Uncoated finish suitable for non-ferrous metals and plastics
• Tight mill diameter tolerance of +0.000 / -0.002 inches for precision fitment

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC and manual vertical milling machines accepting a 3/16 inch shank diameter via collet or end mill holder.

Installation Notes

Installation and use should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is powered down before loading or removing the end mill. Seat the shank fully in the collet to the recommended gauge depth and torque the collet nut per the collet manufacturer specification. Verify runout with a dial indicator before beginning cuts to confirm proper tool holding and avoid premature edge wear.
