The C.S. Osborne K-358 is a professional-grade 28-piece transfer punch set designed for accurate hole location transfer in machining, fabrication, and metalworking applications. This comprehensive set eliminates guesswork when duplicating hole patterns between mating parts or transferring hole centers from templates to workpieces.

Key Features:

• 28 imperial-sized transfer punches ranging from 3/32" to 17/32" in 1/64" increments
• Heat-treated alloy steel construction for durability and long service life
• Black oxide finish provides corrosion resistance
• Includes sturdy metal storage rack with clearly marked sizes for quick selection
• Each punch measures 4-7/8" in overall length for optimal reach and control
• Properly hardened points maintain accuracy through repeated use

Transfer punches are essential tools for machinists, tool and die makers, fabricators, and automotive technicians. Simply insert the appropriately sized punch into an existing hole, align your workpiece, and tap gently with a hammer to mark the exact hole center on the mating surface. This ensures precise alignment when drilling matching holes for fasteners, dowel pins, or other hardware. The organized rack keeps all 28 sizes readily accessible and protected in your toolbox or workbench.
