Accupro 12181250 Square End Mill 1 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 12181250 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. With a 1 inch cutting diameter and a 1-3/4 inch length of cut, this tool handles slotting, profiling, and peripheral milling in a wide range of ferrous and non-ferrous materials. The micrograin carbide construction paired with an AlTiN coating delivers high hardness and thermal resistance at elevated cutting speeds. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. This end mill is installed and used by machinists and CNC operators in job shops, production facilities, and tool rooms.

This 2-flute configuration is well suited for applications requiring deeper cuts or work in softer materials where chip clearance is a priority. The centercutting geometry allows plunge milling in addition to lateral passes. The right-hand cut and right-hand spiral flute are standard for conventional and climb milling on CNC machining centers and manual knee mills. The regular length designation makes this tool a general-purpose option for everyday milling tasks where extended reach is not required.

Key Features

• 1 inch cutting diameter with a mill diameter tolerance of +0.000 / -0.002 inches for consistent fit and finish
• Micrograin solid carbide substrate provides rigidity and wear resistance
• AlTiN finish extends tool life at high cutting temperatures
• 40-degree spiral helix angle improves chip flow and reduces cutting forces
• Centercutting design enables plunge entry without a pre-drilled hole
• Right-hand cut with right-hand flute — compatible with standard spindle rotation

Compatibility

Designed as a direct-fit replacement or standard tooling option for CNC machining centers and manual mills accepting a 1 inch straight shank with a shank diameter tolerance of -0.0001 / -0.0004 inches.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank in a collet chuck, end mill holder, or Weldon-style holder to the full recommended engagement depth before operation. Verify runout with a dial indicator before cutting. Never exceed the rated depth of cut or feed rate for the workpiece material and machine spindle horsepower.
