Product Information
Full details
This Charnwood 300mm, 72-tooth Tungsten Carbide Tipped (TCT) circular saw blade is designed for professional users seeking a fine finish when crosscutting and versatility for ripping. Its precision laser-cut SK5 steel plate, resin-filled slots for noise reduction, and black electroplated finish offer durability and performance. A key caveat is its unsuitability for radial arm or mitre saws, demanding careful application on compatible machines.

FAQs
What is the main purpose of the 72 teeth on this blade?
The 72 teeth are optimized for a fine finish, particularly effective for crosscutting operations in various wood types. While it can also be used for ripping, a blade with fewer teeth might be more efficient for pure ripping tasks.
Can I use this blade on my mitre saw?
No, this blade is NOT suitable for radial arm saws or mitre saws. It is designed specifically for table saws and bench saws with a 30mm bore.
How do I clean resin and pitch build-up from the blade?
The black electroplated finish aids in easy cleaning. Use a suitable blade cleaner or solvent specifically designed for saw blades. Avoid abrasive materials that could damage the carbide tips or plate.
What does 'SK5 Steel' refer to?
SK5 steel is a high-quality Japanese carbon tool steel known for its hardness, strength, and durability, used here for the blade's plate to ensure precision and longevity.
What is the benefit of the resin-filled slots?
The resin-filled slots absorb vibrations and dampen noise during operation, reducing the noise level by up to 30%. They also allow the blade to expand and contract with heat without warping.
What does ATB tooth pattern mean?
ATB stands for Alternative Top Bevel. This tooth geometry is designed for fast, clean cuts, particularly effective for crosscutting and general-purpose sawing.
What is the maximum safe speed for this blade?
The maximum recommended RPM for this blade is 6500 RPM.
Troubleshooting
Blade vibrates excessively during use
Ensure the blade is correctly and securely mounted to the saw arbor. Check for any damage to the teeth or plate. Make sure the arbor nut is tightened properly.
Poor cut quality (e.g., tear-out, burning)
Verify that the blade is appropriate for the material being cut. Ensure the blade is sharp and free from resin build-up. Check saw speed and feed rate are suitable.
Blade making excessive noise
The resin-filled slots are designed to reduce noise. If noise is still high, ensure the blade is undamaged and correctly installed. Consider using hearing protection.

Setup, Compatibility & Care
Setup
Ensure the blade is securely mounted to your table saw arbor with the correct bore size (30mm). Always wear appropriate safety gear, including eye protection and hearing protection, when operating a saw.
