The Makita B-47058 150mm Metal Cutting Circular Saw Blade is designed for professional metalworkers and fabricators who require clean, burr-free cuts in steel and stainless steel. It delivers exceptional precision and longevity thanks to its high-tooth-count tungsten carbide design; however, users must strictly adhere to specific RPM limits to prevent blade damage or overheating when cutting harder alloys.

No, this blade is specifically designed for steel and stainless steel. For aluminium, use the Makita B-47020 blade.
No, it is designed for metal-cutting saws with a 20mm arbor. Always check your tool manual for compatibility.
When the blade begins to produce excessive burrs, requires more force to push through the metal, or shows chipped carbide tips.
While TCT blades are designed for dry cutting, keeping the cut steady and cool through controlled feed rates is more important than external liquid cooling.
It is intended for thin-to-medium gauge steel; consult your circular saw's depth capacity and torque limits before attempting thick cuts.
Reduce your feed rate and ensure you are not forcing the saw through the material too quickly.
Check that the workpiece is securely clamped and that the blade is fully tightened on the arbor.
The blade may be dull; inspect the carbide teeth for signs of wear or chipped edges and replace if necessary.
To install the blade, ensure the power source is disconnected. Align the blade's rotation arrow with the direction of the saw arbor. The 20mm arbor is standard for Makita metal-cutting circular saws, but always verify your specific tool's arbor requirements before installation. After use, inspect the teeth for metal buildup or chipped carbide. Wipe the blade with a light machine oil to prevent rust if working in humid environments. Avoid dropping the blade, as carbide tips are brittle and can fracture upon impact with hard concrete or steel floors.
