Accupro 2500023 Square End Mill 0.25in 3 Flute Solid Carbide

Product Description

The ACCUPRO 2500023 is a solid carbide square end mill designed for precision metal removal in milling operations. It measures 0.25 inches in diameter with a 0.75-inch length of cut, a 0.25-inch shank diameter, and a 2.5-inch overall length. The three-flute, right-hand spiral geometry paired with a ZrN (zirconium nitride) coating supports efficient chip evacuation and extended tool life in demanding cutting environments. The micrograin carbide substrate adds edge strength and wear resistance. Machinists and tooling professionals in job shops, production facilities, and maintenance environments are the primary users of this type of end mill.

This end mill is suited for slotting, profiling, and peripheral milling in ferrous and non-ferrous materials. The center-cutting design allows for direct plunge entry, expanding its usefulness across a range of milling strategies. The variable helix flute geometry helps reduce harmonic chatter during cuts, making it a practical choice for finishing passes and interrupted cuts alike. It is packaged and sold individually.

Key Features

• Solid micrograin carbide construction for high wear resistance and edge retention
• ZrN coating reduces friction and extends tool life in abrasive materials
• Variable helix design minimizes chatter and improves surface finish
• Center-cutting capable — supports direct plunge milling
• Right-hand cut and right-hand flute spiral for standard spindle compatibility
• Regular length type with 0.75-inch LOC suits most general-purpose milling depths

Compatibility

Designed as a standard shank solid carbide square end mill compatible with any milling machine, machining center, or CNC router equipped with a 0.25-inch collet, end mill holder, or equivalent toolholding system.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from its holder. Seat the shank to the full recommended engagement depth in the collet or holder and torque the retention system per the toolholder manufacturer specifications. Inspect the cutting edges for chips or wear before each use and replace the tool at the first sign of edge degradation to maintain dimensional accuracy and workpiece surface quality.
