Accupro 12177388 Square End Mill 1 in 7 Flute Solid Carbide

Product Description

The ACCUPRO 12177388 is a solid carbide square end mill designed for precision milling operations in metal cutting and machining applications. It measures 1 inch in diameter with a 1-1/4 inch length of cut and a 6 inch overall length. The 7-flute, spiral-flute geometry combined with a 37.5-degree helix angle delivers smooth chip evacuation and improved surface finish on ferrous and non-ferrous materials. The nACRo finish provides enhanced wear resistance and heat tolerance during high-speed cutting. This tool is used by machinists and CNC operators working in job shops, production facilities, and tool rooms.

This end mill is suited for slotting, profiling, and peripheral milling in materials where a high flute count improves finish quality and reduces chatter. The centercutting design allows plunge entry, adding flexibility in programming. The extended reach configuration, with a 3-1/8 inch reach length, accommodates deeper pockets and features that require clearance past the shank. Right-hand cut and right-hand flute orientation are standard for conventional CNC milling setups. Micrograin carbide construction supports use in demanding cutting conditions where tool life is a priority.

Key Features

• 1 inch mill diameter with mill diameter tolerance of +0.000 / -0.002 inches
• 7-flute spiral geometry with 37.5-degree helix angle for improved finish and chip flow
• nACRo coating for elevated wear resistance and thermal stability
• Centercutting design enables direct plunge entry without a pre-drilled hole
• Extended reach with 3-1/8 inch reach length for deep-pocket access
• Micrograin solid carbide construction for rigidity and edge retention

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill 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 is performed by a qualified machinist or CNC operator. Ensure the machine spindle and tool holder are clean and free of debris before seating the shank. Confirm proper runout with an indicator after tool installation and before initiating a cut. Follow machine tool manufacturer guidelines and applicable shop safety protocols when securing and operating end mills at elevated spindle speeds.
