Accupro 12182319 Square End Mill 1/32 in 4 Flute Carbide

Product Description

The ACCUPRO 12182319 is a 4-flute solid carbide square end mill designed for precision milling in tight tolerances and small-feature work. With a mill diameter of 0.0313 inches (1/32 inch) and a 3/32-inch length of cut, this tool is built for fine detail passes in ferrous and non-ferrous materials. The micrograin carbide construction provides hardness and edge retention at small diameters where high-speed steel would deflect or fail. The 30-degree helix spiral flute geometry promotes chip evacuation and smooth cutting action. Machinists and toolroom professionals use this end mill for micro-machining, engraving, and contour milling applications.

This end mill fits standard CNC machining centers and manual knee mills equipped with a 1/8-inch shank collet. The regular-length geometry and 1-1/2-inch overall length keep the tool rigid, reducing runout and chatter during light finishing passes. Right-hand cut and right-hand flute orientation are standard for conventional CNC setups. The centercutting design allows plunge entry, adding flexibility for ramping and helical interpolation operations common in die and mold work, prototype machining, and precision part production.

Key Features

• 0.0313-inch (1/32-inch) mill diameter for micro and fine-detail milling
• 4-flute spiral design with 30-degree helix angle for efficient chip removal
• Solid micrograin carbide construction for edge hardness and wear resistance
• Centercutting capable — supports plunge, ramp, and helical entry
• Right-hand cut, right-hand flute for standard CNC compatibility
• Uncoated finish suitable for a range of ferrous and non-ferrous workpiece materials

Compatibility

Designed for use in CNC machining centers and manual mills equipped with 1/8-inch collets or tool holders accepting a 1/8-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and locked before inserting or removing the end mill from the collet. Seat the shank to the recommended collet depth and torque the drawbar or nut to the machine manufacturer specification. At 1/32-inch diameter, this tool is highly susceptible to breakage from excessive feed rate, runout, or improper clamping — verify collet condition and minimize overhang before starting the cut.
