Seco 63005204 Tool Bit Blank WKE45 Cobalt Rectangle

Product Description

The SECO 63005204 is a solid cobalt tool bit blank ground to a rectangular profile and intended for custom tooling applications in machining environments. Manufactured from WKE45-grade cobalt high-speed steel, this blank offers the toughness and wear resistance needed for form tools, fly cutters, and other shop-ground cutting tools. It measures 3/8 inches wide by 1 inch high with an overall length of 6 inches, providing sufficient material stock for a range of custom geometries. Machinists and tool-and-die professionals select this blank when standard insert tooling cannot meet the geometry required for a specific operation.

This blank is suited for use in manual lathes, milling machines, shapers, and other machine tool setups where a custom-ground cutting profile is required. It is appropriate for both job shop and production environments where the operator needs to grind a specific rake angle, clearance angle, or profile form directly onto the blank. The rectangular cross-section makes it compatible with standard tool holders and boring bar setups that accept flat-sided HSS blanks.

Key Features

• WKE45-grade cobalt high-speed steel for elevated hardness and heat resistance compared to standard M2 HSS
• Rectangular cross-section at 3/8 inches wide by 1 inch high for rigid tool holder seating
• 6-inch overall length provides ample stock for grinding multiple cutting edges or custom profiles
• Solid blank construction allows full custom grinding to any geometry required by the application
• Consistent material grade throughout — no coating or substrate layers to interrupt regrinding

Compatibility

Designed as a general-purpose tool bit blank for use in standard tool holders and setups that accept 3/8 inch by 1 inch rectangular HSS blanks across manual and CNC lathe, mill, and shaper applications.

Installation Notes

Tool bit blanks are ground to final geometry by a machinist or tool grinder before use in a cutting application. A bench or pedestal grinder fitted with an appropriate wheel for high-speed steel is the standard equipment for this operation. Secure the blank firmly in the tool holder after grinding and verify clearance angles before engaging the workpiece. Follow shop safety protocols for grinding, including eye protection and wheel guard use.
