Seco 03163 Parallel Cutoff Blade Cobalt WKE45

Product Description

The SECO 03163 is a parallel-style cutoff blade designed for parting and grooving operations on CNC lathes and turning centers. Manufactured from WKE45 cobalt high-speed steel with a bright finish, this blade provides the rigidity and edge retention needed for consistent, accurate cutoff work. It measures 3 mm wide, 16 mm high, and 140 mm long, fitting standard blade-style toolholders used across production and job-shop turning applications. Machinists and CNC operators install this blade when parting off workpieces or cutting grooves that demand a precise, narrow kerf and stable tool engagement.

This cutoff blade suits metalworking operations on steel, stainless steel, and similar ferrous materials where cobalt tooling is the preferred grade. The parallel blade style is a common format for blade-type parting toolholders found in both manual and CNC turning setups. Its 140 mm length accommodates a range of holder depths, and the 3 mm width is a standard parting width for medium-diameter workpieces. Sold individually, it is suited for production environments that replace worn blades without changing the full holder assembly.

Key Features

• Parallel blade style for consistent engagement in blade-type parting toolholders
• WKE45 cobalt high-speed steel grade for improved red hardness and wear resistance
• Bright finish for dimensional accuracy and reduced surface friction during cutting
• 3 mm cutting width minimizes material loss at parting operations
• 140 mm overall length fits a wide range of blade toolholder depths
• 16 mm blade height provides rigidity under cutting loads

Compatibility

Designed as a direct-fit replacement for parallel blade-style parting and grooving toolholders that accept a 3 mm wide by 16 mm high blade profile.

Installation Notes

Installation is performed by a machinist or CNC toolroom technician. Disengage machine power and confirm the spindle is fully stopped before removing or seating the blade. Secure the blade in the toolholder to the clamp torque specified by the toolholder manufacturer. Verify blade runout and holder alignment before returning the machine to service.
