Accupro 12176941 Square End Mill 3/4 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12176941 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. It features a 3/4 inch cutting diameter with a 1-1/2 inch length of cut, a matching 3/4 inch shank diameter, and a 6 inch overall length, placing it in the long-length category for extended reach applications. The 4-flute spiral geometry with a 40-degree helix angle promotes efficient chip evacuation and smooth finishes. Micrograin carbide construction delivers the hardness and edge retention needed for demanding production environments. This end mill is centercutting, allowing plunge entry, and runs right-hand cut with right-hand fluting.

This end mill is suited for milling, slotting, profiling, and plunging operations on machining centers and CNC mills in job shop and production environments. The long overall length makes it appropriate for workpiece setups requiring additional clearance between the spindle and the part. It is installed and operated by machinists and CNC programmers working in metalworking, tooling, and manufacturing trades. The uncoated finish makes it a practical choice for applications where coolant is used or where coating adhesion to the base material is not a priority.

Key Features

• Solid micrograin carbide construction for hardness and edge retention
• 40-degree helix angle spiral flute for efficient chip evacuation
• Centercutting design allows direct plunge entry into workpiece
• Right-hand cut and right-hand flute geometry for standard spindle rotation
• Long-length classification at 6 inches OAL for extended reach setups
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent fit and finish

Compatibility

Designed as an OEM-style replacement or direct-fit cutting tool for CNC machining centers and manual mills accepting a 3/4 inch straight shank end mill holder or collet chuck.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. The tool must be secured in a properly sized collet chuck or end mill holder rated for the 3/4 inch shank diameter before spindle startup. Verify runout with a dial indicator after mounting to minimize vibration and premature edge wear. Always confirm spindle direction and feed-rate programming match the right-hand cut specification before engaging the workpiece.
