Accupro 14797243 Square End Mill 1/16 in 3 Flute Carbide

Product Description

The ACCUPRO 14797243 is a solid carbide square end mill designed for precision milling in demanding machining environments. With a 1/16 inch (0.0625 inch) mill diameter and a 1/2 inch length of cut, this single-end tool handles slotting, profiling, and finishing passes in tight geometries. The AlTiN (aluminum titanium nitride) coating increases surface hardness and thermal resistance, extending tool life in hard ferrous materials. A 30-degree helix angle promotes efficient chip evacuation and reduces cutting forces. Machinists and CNC operators in job shops, tool rooms, and production environments rely on this type of end mill for small-feature work where dimensional accuracy is critical.

This end mill is suited for milling operations on steel, stainless steel, cast iron, titanium, and similar hard materials where AlTiN coating performance is advantageous. The extended reach design, with a 1 inch neck length and 1 inch reach length, allows access to recessed features and deep pockets without the need for specialty tooling extensions. The 1/8 inch shank diameter fits standard collets and tool holders used across most CNC machining centers and manual milling machines. It is a single-end tool intended for right-hand cutting with right-hand flute direction.

Key Features

• 1/16 inch mill diameter with plus 0.0000 / minus 0.0010 inch diameter tolerance for precise dimensional control
• AlTiN coating for elevated hardness and heat resistance in ferrous and hard-alloy machining
• 3-flute, right-hand spiral geometry with 30-degree helix angle for improved chip flow
• Extended reach with 1 inch neck length and 1 inch reach length for deep or recessed features
• Center-cutting capability allows direct plunge entry without pre-drilling
• Micrograin solid carbide construction provides rigidity and wear resistance at small diameters

Compatibility

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

Installation Notes

Install and remove end mills only with the machine spindle fully stopped and locked out per shop lockout/tagout procedures. Confirm collet size matches the 1/8 inch shank before tightening to manufacturer-specified torque for the collet system in use. Inspect the cutting edges and coating for chips or wear before each use, particularly at this small diameter where tool deflection and breakage risk are elevated. Follow the tool manufacturer and machine OEM recommendations for speeds, feeds, and depth of cut for the specific workpiece material.
