Value Collection 01108398 Drill Blank Size 39 Hss 2-3/8 in

Product Description

The VALUE COLLECTION 01108398 is a wire gauge size 39 drill blank ground from high speed steel and supplied in a bright, uncoated finish. At 0.0995 inches in diameter and 2-3/8 inches overall length, this blank is intended for machinists and toolmakers who need to produce custom drills, reamers, or precision cutting tools ground to a specific geometry. High speed steel construction provides the hardness and toughness required to hold an edge through repeated regrinding. The uncoated finish allows the user to apply any preferred coating or treatment after final grinding without adhesion concerns.

Wire gauge drill blanks in the size 39 range are commonly used in toolrooms, machine shops, and production environments where off-the-shelf drill geometries do not meet application requirements. This blank is well suited for custom tooling fabrication, jig and fixture work, and repair operations. It is a standard single-piece item appropriate for bench grinder or tool-and-cutter grinder setups.

Key Features

• Wire gauge size 39 corresponds to 0.0995 inch diameter for precise tooling applications
• High speed steel construction supports regrinding and edge retention under normal cutting loads
• Bright, uncoated finish is ready for custom coating or treatment after grinding
• 2-3/8 inch overall length provides adequate stock for grinding custom flute and point geometries
• Sold individually, allowing single-unit procurement for toolroom or repair use

Compatibility

Designed as a standard wire gauge size 39 drill blank suitable for use in general toolroom and machining applications where a 0.0995 inch diameter high speed steel blank is required.

Installation Notes

Drill blanks require grinding by a qualified toolmaker or machinist using a tool-and-cutter grinder before use as a cutting tool. Secure the blank firmly in the appropriate grinding fixture to maintain consistent geometry. Follow shop safety protocols for grinding operations, including eye protection and proper wheel guarding. Do not attempt to use an unground blank as a drill.
