Value Collection 01108497 Drill Blank Size 49 Hss

Product Description

The VALUE COLLECTION 01108497 is a wire gauge size 49 drill blank ground from high speed steel and left uncoated for a bright finish. At 0.073 inches in diameter and 2 inches overall length, this blank is intended for use as drill rod stock or for fabricating custom cutting tools. High speed steel construction provides the hardness and wear resistance needed for drilling ferrous and non-ferrous metals, plastics, and composites. Machinists, toolmakers, and maintenance professionals stock these blanks when standard twist drills are not available in the required diameter or when a custom point geometry is needed.

Wire gauge drill blanks in the size 49 range are commonly used in toolroom and production environments where precise hole sizing is required. Typical applications include jig and fixture work, printed circuit board tooling, and custom punch-and-die work. The bright uncoated finish makes the blank easy to inspect and suitable for re-grinding to a custom profile on a drill grinder or surface grinder.

Key Features

• Wire gauge size 49 — 0.073 inch decimal equivalent for precision hole sizing
• High speed steel construction for hardness and heat resistance during cutting
• Bright uncoated finish allows easy visual inspection and accepts additional coatings if required
• 2 inch overall length provides sufficient stock for grinding custom point geometries
• Consistent diameter tolerance suitable for use as drill rod or custom tooling stock

Compatibility

Designed as a standard wire gauge size 49 drill blank for use in toolroom applications requiring a 0.073 inch diameter uncoated high speed steel blank.

Installation Notes

Drill blanks are ground to finished size by a qualified toolmaker or machinist using a drill grinder or surface grinder before use as a cutting tool. Secure the blank properly in the grinding fixture to maintain concentricity and the desired point angle. Eye protection and appropriate grinding guards must be used during any grinding operation. Do not attempt to use an unground blank as a drill in a chuck without first establishing the proper cutting geometry.
