Seco 63005972 Tool Bit Blank WKE45 Cobalt Rectangle

Product Description

The SECO 63005972 is a rectangular cobalt tool bit blank ground to WKE45 material grade specification. It measures 0.5 inches wide, 1 inch high, and 7 inches in overall length, providing a solid, unground starting stock for machinists and toolroom professionals who need to produce custom cutting tools or specialty form tools. Cobalt high-speed steel offers greater heat and wear resistance than standard M2 HSS, making this blank well-suited for harder workpiece materials and interrupted cuts where edge retention is critical. This blank ships uncoated and unground, ready for custom profiling on a tool and cutter grinder.

This tool bit blank is used in toolroom and production machining environments where standard insert tooling cannot replicate the geometry required for a specific operation. Typical applications include single-point lathe tools, form tools, fly cutters, and boring bar inserts. It is appropriate for use in manual lathes, manual milling machines, and similar conventional machine tools where brazed or ground HSS tooling is the preferred approach. Machinists working with stainless steel, alloy steel, and high-temperature alloys will benefit from the elevated cobalt content of the WKE45 grade.

Key Features

• WKE45 cobalt high-speed steel for improved hot hardness and wear resistance over standard HSS grades
• Rectangular cross-section simplifies fixturing in standard tool holders and vise-type grinder fixtures
• 0.5 inch width by 1 inch height profile provides substantial stock for heavy grinding or regrinding
• 7-inch overall length allows multiple tools to be cut from a single blank, reducing material waste
• Unground and uncoated surface ships ready for custom geometry profiling

Compatibility

Designed as a general-purpose tool bit blank for use in standard toolroom and production machining applications requiring WKE45-grade cobalt high-speed steel in a rectangular profile.

Installation Notes

Grinding of HSS tool bit blanks should be performed by a qualified machinist using appropriate wheel dressing, coolant, and personal protective equipment including eye protection. Secure the blank firmly in a tool and cutter grinder fixture or surface grinder magnetic chuck before grinding to prevent movement. Allow adequate cooling between passes to avoid thermal cracking of the cobalt steel. Dispose of grinding swarf in accordance with applicable shop safety and environmental regulations.
