Description
The SECO 03017 is a parallel-style cutoff blade designed for precision parting and grooving operations on CNC lathes and turning centers. Manufactured from WKE45 cobalt high-speed steel with a bright finish, this blade measures 3 mm wide, 12 mm high, and 120 mm in overall length. The parallel geometry provides consistent blade positioning and repeatable depth of cut across a range of workpiece materials. It is installed by machinists and tool and die professionals working in metalworking and production turning environments where tight tolerances and clean parting cuts are required.
This cutoff blade suits parting and grooving applications on manual and CNC turning equipment. The WKE45 cobalt grade offers improved heat and wear resistance compared to standard high-speed steel, making it well suited for interrupted cuts and tougher ferrous and non-ferrous materials. The bright finish indicates an uncoated substrate, which is appropriate for applications where coating buildup would affect dimensional accuracy or where re-grinding is part of the shop workflow.
Key Features
- Parallel blade style for consistent positioning and repeatable parting depth
- WKE45 cobalt high-speed steel grade for elevated wear and heat resistance
- Bright (uncoated) finish suitable for applications requiring re-grinding capability
- 120 mm overall length accommodates standard cutoff blade holders in production turning setups
- 3 mm width delivers narrow kerf for material-efficient parting operations
Compatibility
Designed as a replacement or spare parallel cutoff blade for standard cutoff blade holders accepting a 3 mm wide by 12 mm high blade profile. Verify holder slot dimensions against blade specifications before installation.
Installation Notes
Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the turning machine before seating or removing the blade from its holder. Ensure the blade is fully seated and clamping screws are tightened evenly to prevent blade movement during the cut. Handle the cutting edge with care to avoid chipping the substrate prior to use.
