Value Collection 01100122 Drill Blank 3/16 in Hss

Product Description

The VALUE COLLECTION 01100122 is a high speed steel drill blank designed for use in custom tooling applications where a precision-ground, uncoated steel rod is required before final shaping or grinding. At 3/16 inch (0.1875 inch) in diameter and 3-1/2 inches in overall length, this blank provides the raw stock machinists and tool grinders need to fabricate step drills, custom reamers, punches, and other cutting tools. The bright, uncoated finish indicates an unhardened or through-hardened HSS substrate ready for grinding to a finished profile. Diameter tolerance is held to +0.0000 to -0.0003 inches for consistent fitment in drill chucks, collets, and fixtures.

Drill blanks of this size are commonly used in machine shops, maintenance facilities, and tool-and-die operations. The 3/16 inch diameter is a standard fractional size well-suited for fabricating small-diameter cutting tools, guide pins, or locating pins. This blank ships individually and is appropriate for low-volume custom tooling work or as a replacement blank when rebuilding tooling assemblies.

Key Features

• High speed steel construction provides hardness and wear resistance for grinding into finished cutting tools
• Diameter: 0.1875 inches (3/16 inch fractional) with a tight tolerance of +0.0000 to -0.0003 inches
• Overall length of 3-1/2 inches offers sufficient stock for most small-diameter tool fabrication tasks
• Bright, uncoated finish allows direct grinding without coating interference
• Sold individually, suitable for single-piece tooling jobs or repair work

Compatibility

Designed as a standard fractional-size HSS drill blank suitable for use in tool grinding and fabrication applications requiring a 3/16 inch diameter round stock with a 3-1/2 inch overall length.

Installation Notes

Drill blanks are machined or ground to a finished tool profile by a qualified machinist or tool grinder using appropriate grinding equipment. Secure the blank in a fixture or collet before grinding to prevent movement and maintain concentricity. Follow all applicable shop safety practices, including eye protection and proper wheel guarding, when grinding high speed steel. Do not attempt to use an unfinished blank as a cutting tool.
