Seco 63007897 Tool Bit Blank WKE45 Cobalt Rectangle

Product Description

The SECO 63007897 is a rectangular cobalt tool bit blank intended for use in custom tooling applications where the end user grinds or profiles the cutting geometry to suit a specific job. Manufactured from WKE45-grade cobalt high-speed steel, this blank measures 0.25 inches wide, 0.5 inches high, and 3 inches in overall length. The WKE45 grade delivers high hardness and wear resistance, making it suitable for interrupted cuts and demanding machining conditions. Machinists and tool grinders select blanks like this when standard insert geometries are unavailable or when a shop-ground profile is required for a specific turning, boring, or forming operation.

This tool bit blank is used in manual lathes, turret lathes, and single-point turning setups found in job shops, maintenance machining environments, and production facilities. The rectangular cross-section is the most common blank format and fits standard tool holders and lantern-style post holders designed for 0.25 inch by 0.5 inch shank profiles. It is appropriate for machining ferrous metals, alloy steels, and other materials where cobalt HSS tooling provides adequate heat and wear resistance at moderate cutting speeds.

Key Features

• WKE45 cobalt high-speed steel grade for elevated hardness and thermal resistance
• Rectangle cross-section for compatibility with standard tool post holders
• 3 inch overall length provides adequate stock for grinding multiple profiles over the tool life
• Unground blank allows the machinist to profile any cutting geometry required
• 0.25 inch width by 0.5 inch height shank dimensions match common tool holder slots

Compatibility

Designed as a general-purpose cobalt HSS tool bit blank for use in standard tool holders and lantern-style post holders that accept a 0.25 inch by 0.5 inch rectangular shank profile.

Installation Notes

Tool bit blanks require grinding to a finished cutting geometry before use and should be shaped by a qualified machinist or tool grinder using appropriate wheel speeds and coolant to prevent overheating the cobalt steel. Ensure the tool holder set screws are fully tightened and the blank is seated squarely before any cutting operation. Follow applicable shop safety practices and machine guarding requirements when grinding or operating the tool.
