Accupro 14797150 Square End Mill 0.02 in 3 Flute Carbide

Product Description

The ACCUPRO 14797150 is a solid carbide square end mill designed for precision milling in metal, composite, and hard-material applications. Built from micrograin carbide stock, this single-end tool runs a 0.02-inch cutting diameter with a 1/32-inch (0.03-inch decimal) length of cut and a 30-degree right-hand spiral helix. The bright, uncoated finish keeps the tool at its ground dimension without added coating buildup, which matters at this diameter. Three flutes provide chip evacuation balanced against edge strength at micro-diameter scale. Machinists and tool-and-die professionals use this end mill where tight tolerances and small-feature geometry are required.

This end mill is suited for light finishing passes and fine-feature slotting in CNC machining centers and manual mills capable of holding the high spindle speeds required at 0.02-inch diameter. The 1/8-inch shank fits standard ER or collet toolholding systems common in precision machining setups. Extended reach geometry allows access to recessed or deep-pocket features. The 2.5-inch overall length gives clearance in typical small-part fixturing scenarios without excessive overhang.

Key Features

• 0.02-inch cutting diameter with micrograin solid carbide construction for edge integrity at micro scale
• 3 flutes with right-hand spiral flute direction for efficient chip evacuation
• 30-degree helix angle balances cutting forces and finish quality
• Centercutting capable — supports plunge entry without a pre-drilled pilot
• Extended reach design for access to recessed features and deep pockets
• Bright/uncoated finish preserves ground diameter tolerance at the cutting edge

Compatibility

Designed as a general-purpose replacement or production micro end mill for CNC machining centers and precision manual mills using 1/8-inch collet or ER toolholding systems.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the collet holder. Seat the shank to the full depth recommended by the toolholder manufacturer and torque the collet nut according to toolholder specifications. At 0.02-inch diameter, tool deflection and runout are critical — verify collet condition and minimize overhang beyond what the setup requires.
