Seco 63003029 Parallel Cutoff Blade WKE45 Cobalt 7 Inch

Product Description

The SECO 63003029 is a parallel-style cutoff blade manufactured from WKE45-grade cobalt high-speed steel with a bright finish. Designed for parting and grooving operations on manual and CNC lathes, this blade measures 7 inches in overall length, 0.875 inches in height, and 0.156 inches in width. The cobalt grade delivers elevated heat resistance and edge retention compared to standard high-speed steel, making it suitable for cutting tougher workpiece materials at higher surface speeds. Machinists and toolroom professionals install this blade in compatible cutoff blade holders for parting stock on turning centers and engine lathes.

This cutoff blade is suited for parting operations in metalworking environments including production shops, maintenance toolrooms, and job shops. The parallel blade style provides consistent support along the full blade height within the holder, reducing deflection during deep parting cuts. It is sized for use in standard parallel-bore cutoff blade holders that accept a 0.156-inch-wide blade. Typical materials parted with this grade include alloy steels, stainless steels, and heat-resistant alloys where cobalt-grade tooling is specified.

Key Features

• WKE45 cobalt high-speed steel construction for improved heat and wear resistance
• Parallel blade style for full-contact seating in compatible blade holders
• Bright finish for dimensional consistency and ease of inspection
• 0.156-inch cutting width suitable for standard parting operations
• 7-inch overall length accommodates deep reaches in standard cutoff holders

Compatibility

Designed as an OEM-style replacement or standard replacement cutoff blade for parallel-style cutoff blade holders accepting a 0.156-inch-wide by 0.875-inch-high blade in metalworking lathe applications.

Installation Notes

Cutoff blades are installed and serviced by machinists on manual or CNC lathes. Power down and lock out the machine before removing or seating the blade in the holder. Ensure the blade is clamped securely and seated fully against the holder bore before resuming operation. Do not exceed the blade height exposure recommended by the holder manufacturer, as excessive overhang increases deflection and blade breakage risk.
