Chicago-latrobe 57833 Hss Drill Blank Set 29 Pc 1/16-1/2 in

Product Description

The CHICAGO-LATROBE 57833 is a 29-piece high speed steel drill blank set covering a size range from 1/16 inch to 1/2 inch in 1/64-inch step increments. Drill blanks are uncoated, ground-stock rods used as raw material for custom tooling fabrication, tool and cutter grinding, and gauge or fixture work. The bright (polished) finish indicates an uncoated, as-ground surface condition suited for machining and grinding applications where a consistent, clean surface is required. This set is a standard resource for tool rooms, machine shops, and maintenance departments that produce or modify cutting tools in-house.

This set is appropriate for tool room and industrial maintenance environments where technicians need a ready supply of HSS blank stock across a broad range of diameters. The 29-piece assortment provides coverage from small-diameter work at 1/16 inch up through 1/2 inch, reducing the need for individual blank sourcing. Typical users include tool and die makers, machinist apprentices maintaining tool inventory, and maintenance technicians who grind their own drills or fabricate custom gauging pins and fixture components.

Key Features

Compatibility

Designed as general-purpose HSS drill blank stock for tool room and industrial machining applications requiring ground-stock rod material across a 1/16-inch to 1/2-inch diameter range.

Installation Notes

Drill blanks are raw stock and require secondary grinding or machining before use as finished cutting tools or gauges. Handle with clean dry hands or shop gloves to avoid surface contamination that can interfere with subsequent grinding operations. Store in the provided case to prevent rolling contact and edge damage between blanks. Secondary grinding should be performed by qualified toolmakers following standard tool room safety practices.
