Accupro 00198911 Carbide Split-end Blank 5/16 in Single Squared

Product Description

The ACCUPRO 00198911 is a solid carbide split-end blank designed for precision tool grinding and custom end mill fabrication. The blank measures 5/16 inches in diameter with a 4-inch overall length (OAL) and a 1/2-inch split length. The end style is single squared, making it well-suited for applications where a flat, perpendicular end geometry is required before the grinding operation begins. Solid carbide construction provides the rigidity and wear resistance needed to hold tight dimensional tolerances throughout the grinding process. Diameter tolerance is held to +0.000 to -0.0005 inches, ensuring predictable stock removal when the blank is ground to final tool geometry.

This split-end blank is used primarily in tool-and-cutter grinding operations at machine shops, toolrooms, and industrial grinding facilities. It serves as the raw stock for producing custom rotary cutting tools, including end mills and similar fluted tools. The split-end feature allows the grinding wheel to access the cutting face geometry during the fluting process. It is suited for use in CNC tool grinding machines and manual surface or cylindrical grinders operated by qualified tool grinders and machinists.

Key Features

• Solid carbide construction for high rigidity and wear resistance
• 5/16-inch diameter with a tight tolerance of +0.000 to -0.0005 inches
• 4-inch overall length provides sufficient stock for most standard end mill geometries
• 1/2-inch split length for grinding wheel access during fluting operations
• Single squared end style ensures a flat, perpendicular reference surface

Compatibility

Designed as a general-purpose solid carbide blank compatible with standard tool-and-cutter grinding setups that accept 5/16-inch diameter round stock.

Installation Notes

Handling and mounting of carbide blanks should be performed by trained machinists or tool grinders using appropriate wheel guards and personal protective equipment. Secure the blank firmly in the grinding fixture or collet before starting the machine. Carbide is brittle and can chip if dropped or subjected to lateral impact loads during setup. Follow applicable shop safety standards and machine manufacturer guidelines for wheel speed and coolant use when grinding carbide.
