Accupro 2500450 Square End Mill 8mm 2 Flute Carbide Zrn

Product Description

The ACCUPRO 2500450 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. Built from micrograin carbide and finished with a ZrN (zirconium nitride) coating, it delivers extended tool life and improved wear resistance in a wide range of ferrous and non-ferrous materials. The 8 mm cutting diameter pairs with a 45-degree helix angle and 2-flute geometry to promote efficient chip evacuation and smooth cutting action. This is a centercutting, single-end tool with right-hand cutting and right-hand flute direction, making it suitable for slotting, profiling, and plunge milling applications. Machinists and CNC operators in job shops and production environments are the primary users.

This end mill is sized for medium-duty milling work where a regular-length tool is appropriate. The 19 mm length of cut and 65 mm overall length position it as a general-purpose option for most vertical machining center and manual mill setups. Its spiral flute design and micrograin carbide substrate make it a dependable choice when consistent surface finish and dimensional accuracy are required in steel, aluminum, and similar workpiece materials.

Key Features

• Solid micrograin carbide substrate for rigidity and edge retention
• ZrN coating increases surface hardness and reduces friction at the cutting edge
• 45-degree helix angle promotes aggressive chip evacuation and reduces cutting forces
• Centercutting geometry allows direct plunge entry into the workpiece
• Right-hand cut and right-hand spiral for standard CNC and manual mill spindle compatibility
• Regular length profile suits most standard toolholding setups without extended-reach holders

Compatibility

Designed as a standard shank solid carbide square end mill compatible with ER collet chucks, shrink-fit holders, and side-lock holders accepting an 8 mm shank diameter.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine spindle fully stopped and the control in an e-stop or locked-out state. Verify shank runout after seating in the holder, as excessive runout accelerates edge wear and degrades surface finish. Apply appropriate cutting fluid or coolant for the workpiece material per shop practice. Consult the machine tool manufacturer guidelines for recommended speeds and feeds when setting up this tool.
