Value Collection 01100247 Drill Blank 3/8 in Hss

Product Description

The VALUE COLLECTION 01100247 is a high speed steel drill blank measuring 3/8 inch in diameter with a 5 inch overall length. Drill blanks are ground, unfluted steel rods used as raw stock for custom tooling applications including the fabrication of special drills, punches, reamers, and other precision cutting tools. This blank arrives in a bright, uncoated finish, which means it retains the base HSS material properties without any additional surface treatment. Machinists and tool-and-die professionals grind these blanks to custom profiles using surface grinders or tool grinders. The 3/8 inch diameter and 5 inch length make this a versatile stock size for a wide range of shop applications.

This drill blank is suited for tool rooms, machine shops, and maintenance departments that fabricate or recondition cutting tools in-house. It is appropriate for custom tooling applications where standard off-the-shelf drill geometry is not sufficient. The bright finish makes it easy to inspect for surface defects before grinding. This blank is sold individually and is appropriate for low-volume custom tooling work or prototype tool development.

Key Features

• High speed steel construction provides hardness and wear resistance suitable for cutting tool fabrication
• Bright, uncoated finish allows easy visual inspection and straightforward surface grinding
• 3/8 inch diameter accommodates a common range of drill and reamer profiles
• 5 inch overall length provides sufficient stock for most custom tooling applications
• Sold individually, suitable for single-tool fabrication or small batch work

Compatibility

Designed as a general-purpose drill blank for use in tool rooms and machine shops where custom cutting tools are ground to specification from raw stock.

Installation Notes

Drill blanks are raw stock and require grinding by a qualified machinist or tool-and-die maker before use as a cutting tool. Use a surface grinder or tool grinder with appropriate wheel dressing to achieve the desired geometry. Ensure grinding equipment is properly guarded and that the operator follows applicable shop safety standards. Wear eye protection and inspect the blank for cracks or surface defects before beginning any grinding operation.
