Product Information

Full details

The CMT ITK Plus Finish Saw Blade (271.250.42M) is a precision-engineered tool designed for professional woodworkers and serious hobbyists who prioritize clean, accurate cuts. Its primary benefit is the thin-kerf architecture, which minimizes material loss and reduces the load on saw motors, making it perfect for both corded and cordless tools. The main caveat is that, as a finish blade, it is optimized for quality of cut in hardwoods, softwoods, and plywood rather than heavy-duty, high-speed rip cutting of thick, rough-sawn lumber.

FAQs

Can I use this blade for ripping lumber?

Yes, it is designed for both rip and crosscut applications, though it is optimized for finish quality.

Is this blade suitable for cordless saws?

Yes, its thin-kerf design makes it highly efficient for cordless tools as it requires less power to drive through the material.

Does this blade work on a 25.4mm (1-inch) arbor?

No, this blade has a 30mm bore. You would need a 30mm to 1-inch bushing adapter if your saw requires one.

How often should I have the blade sharpened?

Sharpening frequency depends on usage; generally, if you notice increased resistance or burning, it is time to have it professionally sharpened.

Can I cut metal with this blade?

No, this blade is specifically engineered for wood and wood-based products only.

Troubleshooting

Blade creates burn marks on the wood

Reduce feed speed or ensure the blade height is set correctly to allow teeth to clear the wood surface.

Excessive vibration during operation

Check that the blade is properly seated on the arbor and the flange nut is tightened securely.

Poor cut quality or splintering

Clean resin buildup from the teeth; if splintering persists, verify that the zero-clearance insert is properly fitted to the table saw.

Pros and Cons

Pros

  • Superior finish quality reduces the need for sanding
  • Thin kerf design saves material and reduces saw motor strain
  • Excellent for both corded and cordless saw platforms
  • High-grade carbide tips ensure long-term sharpness
  • Versatile for both rip and crosscut operations

Cons

  • Thin-kerf design may experience more blade vibration in extreme thick-stock applications
  • Not intended for heavy-duty demolition or cutting through nails
  • Requires careful alignment on table saws to prevent deflection

Setup, Compatibility & Care

  1. Installation: Ensure the saw is disconnected from power. Align the blade rotation arrow with the direction of the saw arbor. Tighten the arbor nut securely using the tool-provided wrench.
  2. Compatibility: The 30mm bore fits most European-style miter and table saws. Check your saw manual to ensure it accepts 250mm diameter blades.
  3. Maintenance: Periodically clean the blade body with a resin-removing spray to prevent friction buildup. Use a soft-bristled brush to remove pitch from the teeth.
  4. Storage: Store the blade in its original packaging or a blade hanger to protect the carbide teeth from chipping when not in use.
