Accupro 12177337 Corner Radius End Mill 1.2mm 2-flute Carbide

Product Description

The ACCUPRO 12177337 is a solid carbide corner radius end mill designed for precision milling in tight-tolerance applications. It features a 1.2 mm cutting diameter with a 0.1 mm corner radius, producing controlled edge geometry that reduces chipping on hard materials. The 2-flute, right-hand spiral configuration supports chip evacuation in ferrous and non-ferrous materials alike. With a 30-degree helix angle and centercutting capability, this end mill handles both plunge and contour operations. The bright, uncoated finish makes it suitable for applications where coating buildup or contamination is a concern. Machinists and toolroom professionals use this tool in CNC machining centers and manual mills requiring fine detail work.

This end mill is suited for small-feature milling operations in tool and die, mold making, medical device machining, and precision component manufacturing. The extended reach design, with a 20 mm reach length and 6 mm shank diameter, allows access to recessed areas and deep-pocket features without excessive tool deflection. The single-end configuration means the tool is replaced rather than flipped when the cutting end is worn, which is standard practice at this diameter range.

Key Features

• 1.2 mm cutting diameter with 0.1 mm corner radius for fine-detail contour work
• Solid carbide micrograin construction for rigidity and wear resistance at small diameters
• 2-flute right-hand spiral with 30-degree helix for efficient chip evacuation
• Centercutting design enables direct plunge entry into workpiece material
• Extended reach with 20 mm reach length for access to deep or recessed features
• Bright, uncoated finish suitable for applications requiring an uncoated tool surface

Compatibility

Designed as an OEM-style replacement or standard tooling option for CNC machining centers and manual mills accepting a 6 mm straight shank. Verify spindle collet or tool holder size before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Always power down and lock out the spindle before changing tooling. Seat the shank fully into the collet or tool holder to the manufacturer-specified engagement depth and torque the retention system according to the tool holder manufacturer guidelines. Inspect the corner radius and cutting edges under magnification before use to confirm no chipping occurred during handling.
