Seco 03161 Cutoff Blade Parallel WKE45 Cobalt

Product Description

The SECO 03161 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 delivers consistent edge retention under the thermal and mechanical stress of continuous cutting cycles. It measures 1.5 mm wide, 12.7 mm high, and 100 mm long, making it a direct-fit option for standard cutoff blade holders that accept this form factor. Machinists and tool crib technicians responsible for turning cell tooling will find this blade suited to ferrous and non-ferrous parting applications where dimensional precision matters.

This cutoff blade is intended for use in production turning environments, including both manual and CNC lathe setups. The parallel geometry provides a uniform cross-section along the full blade length, which simplifies depth-of-cut calculations and promotes repeatable positioning in the holder. It is appropriate for shops performing high-volume parting, slotting, and face grooving on bar stock or chucked workpieces. The bright finish is indicative of an uncoated tool, which suits operations where coating interaction with the workpiece material is a concern.

Key Features

• Parallel blade style for consistent cross-section and straightforward holder setup
• WKE45 cobalt high-speed steel material grade for improved heat and wear resistance over standard HSS
• Bright (uncoated) finish suitable for applications where coated tooling is not preferred
• 1.5 mm width minimizes material loss at the parting line
• 100 mm overall length accommodates standard cutoff blade holder reach requirements
• 12.7 mm blade height provides rigidity and support depth in the holder

Compatibility

Designed as an OEM-style replacement or direct supply blade for cutoff blade holders that accept a parallel-style blade measuring 1.5 mm wide, 12.7 mm high, and 100 mm long.

Installation Notes

Cutoff blades should be installed by a qualified machinist or toolroom technician following the lathe manufacturer's clamping torque and blade projection guidelines. Power down and lock out the machine before seating or removing the blade from the holder. Ensure the blade is fully supported in the holder pocket with no side play before resuming cutting operations. Do not exceed the blade holder's rated depth-of-cut or overhang specification for this blade height.
