Accupro 12182274 Square End Mill 3/16 Inch 3 Flute Solid Carbide

Product Description

The ACCUPRO 12182274 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. It features a 3/16 inch (0.1875 inch) mill diameter, a 1 inch length of cut, and a 4 inch overall length, making it a long-length configuration suited for reaching into deeper features. The 3-flute geometry and 40-degree helix angle promote efficient chip evacuation and smooth cutting action. Micrograin carbide construction provides the hardness and edge retention needed for demanding cuts in ferrous and non-ferrous materials. This end mill is uncoated and ships ready for immediate use by machinists and tooling professionals.

This end mill is suited for slot milling, profiling, and peripheral milling in job shop and production environments. The centercutting design allows it to plunge directly into workpiece material, adding versatility to its application range. The long length of cut, spanning up to 1.25 inches in the cut range, makes it effective where standard-length end mills cannot reach. It is a single-end tool intended for use in CNC machining centers, manual mills, and similar setups where a 3/16 inch shank is required.

Key Features

• Solid micrograin carbide construction for hardness and edge retention
• 40-degree helix angle promotes efficient chip flow and reduced chatter
• Centercutting design allows direct plunge entry into material
• Right-hand cut and right-hand spiral flute configuration
• Long-length designation with 4 inch OAL for extended reach applications
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent fitment

Compatibility

Designed as an OEM-style replacement or direct tooling solution for machines accepting a 3/16 inch shank end mill in standard ER collets or equivalent toolholding systems.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the machine spindle is fully powered down and locked out before inserting or removing the end mill from the collet or toolholder. Confirm collet size matches the 3/16 inch shank diameter before clamping. Proper runout check after installation is recommended to avoid premature tool wear or workpiece dimensional error.
