Micro 100 C-4 Tool Bit Blank Brazed Solid Carbide Square

Product Description

The MICRO 100 C-4 is a brazed solid carbide tool bit blank designed for machinists and toolroom professionals who need a precision-ground starting point for custom cutting tools. Measuring 0.25 inches wide by 0.25 inches high with a 2 inch overall length, this square blank provides the raw stock needed to grind single-point lathe tools, boring tools, or specialty cutting geometries to exact application requirements. The brazed solid carbide construction delivers hardness and wear resistance suited to interrupted cuts and abrasive materials where high-speed steel tooling falls short.

This blank is used in precision machining environments including job shops, toolrooms, and production turning operations. It is well suited for applications requiring a custom ground tool profile on manual lathes, CNC lathes, or mill-turn centers. Machinists typically grind the blank to a specific rake, relief, and nose radius based on the workpiece material and operation. The square cross-section allows grinding on all four faces, giving flexibility in tool orientation and relief angles.

Key Features

• Brazed solid carbide construction for high hardness and abrasion resistance
• Square cross-section at 0.25 inches by 0.25 inches supports grinding on all four faces
• 2 inch overall length provides adequate shank for secure tool holder clamping
• Unground blank format allows machinists to create fully custom cutting geometries
• Compact form factor suitable for small-bore and light-duty turning applications

Compatibility

Designed as a general-purpose tool bit blank for use in standard tool holders and blocks accepting 0.25 inch square shank tooling.

Installation Notes

Grinding of carbide tool bit blanks should be performed by a qualified machinist using a silicon carbide or diamond grinding wheel appropriate for carbide substrates. Secure the blank firmly in a tool holder or grinding fixture before grinding to prevent movement and maintain consistent geometry. Always wear appropriate eye protection when grinding carbide. Verify tool holder clamping torque meets the machine tool manufacturer specifications before cutting.
