Accupro 520-MG Single Point Tool Bit 1/2 Inch Carbide

Product Description

The ACCUPRO 520-MG is a single point tool bit ground from micrograin solid carbide and configured for neutral cutting direction. It carries a D-style geometry with a pointed nose profile and an 80-degree included angle, making it well suited for chamfering operations on a lathe or manual turning center. The shank measures 1/2 inch wide by 1/2 inch tall, and the overall length is 3-1/2 inches. The 1/32 inch nose radius delivers a controlled finish at the tip. At 0.05 pounds, it is a compact, dense insert-style bit intended for precision work.

This tool bit is used in manual and CNC turning applications where chamfering, angular profiling, or pointed-nose contouring is required. The neutral cutting direction makes it adaptable to both right-hand and left-hand setups depending on how it is oriented in the tool holder. Machinists, toolroom operators, and maintenance technicians working with steel, cast iron, aluminum, and similar materials will find this geometry appropriate for standard production and prototype chamfer work. The micrograin carbide grade offers fine grain structure for edge stability at moderate to high surface speeds.

Key Features

• Micrograin solid carbide tip for edge retention and wear resistance
• D-style pointed nose profile with 80-degree included angle for chamfering
• Neutral cutting direction for flexible left or right setup orientation
• 1/32 inch nose radius for controlled tip geometry
• 1/2 inch square shank fits standard tool holders and boring bars
• 3-1/2 inch overall length for reach in typical turning setups

Compatibility

Designed as an OEM-style replacement or direct-use single point tool bit for standard 1/2 inch square shank tool holders used in manual lathes and turning centers. Industry standard number D-8.

Installation Notes

Tool bit installation should be performed by a qualified machinist following shop safety procedures and machine tool manufacturer guidelines. Secure the shank firmly in the tool holder with the cutting edge set at the correct center height before beginning any cut. Ensure the machine spindle is fully stopped and the power is locked out before adjusting or replacing the bit. Do not exceed the recommended surface speed for the carbide grade and workpiece material combination.
