Vermont Gage 522000000 Long Drill Blank Hss 1/2 in 36 in

Product Description

The VERMONT GAGE 522000000 is a long drill blank in fractional inch sizing, machined from high speed steel (HSS) with a bright, uncoated finish. It measures 0.5000 inches in diameter with a tight diameter tolerance of plus or minus 0.0010 inches, and an overall length of 36 inches. Drill blanks are precision-ground rod stock used by machinists and toolmakers as raw material for custom cutting tools, gauges, punches, and special-purpose tooling. The HSS construction provides the hardness and wear resistance required for tool grinding and precision fabrication work.

This long drill blank is suited for machine shops, tool and die operations, and precision manufacturing environments where standard drill blank lengths are insufficient. The 36-inch overall length allows toolmakers to cut multiple blanks from a single piece or fabricate unusually long custom tools. The fractional inch diameter of 1/2 inch (0.5000 decimal equivalent) makes it a common choice for reamer blanks, boring bar stock, and similar shop-made tooling. It is typically handled by machinists, toolmakers, and precision grinding specialists.

Key Features

• High speed steel construction for hardness and wear resistance in tool grinding applications
• Bright uncoated finish for consistent surface quality and easy measurement verification
• Tight diameter tolerance of plus 0.0010 inches / minus 0.0010 inches for precision fitment
• 36-inch overall length provides extra stock for long tooling or multiple cuts
• Fractional inch sizing with 0.5000 decimal equivalent for straightforward layout and measurement
• Rod shape suitable for use as blank stock for custom drills, reamers, punches, and gauges

Compatibility

Designed as a general-purpose long drill blank for use in machine shop and tool and die applications requiring a 1/2-inch diameter HSS rod with a 36-inch length.

Installation Notes

Drill blanks are raw stock and require machining, grinding, or cutting before use as finished tooling. Machinists should use appropriate personal protective equipment when cutting or grinding HSS material. Secure the blank properly in a vise or chuck before any machining operation. Allow the material to cool between grinding passes to avoid drawing the temper of the steel.
