## Long description

The Bosch 42403 carbide circular saw blade is a high-performance accessory designed for professional power tools, offering a 400 mm diameter, 30 mm bore, and 30 teeth for efficient and accurate wood cutting applications. Built with robust carbide tips, this circular saw blade ensures clean performance and durability in demanding workshop and construction environments.
Advantages
The carbide-tipped teeth provide extended edge retention and superior wear resistance compared to standard steel blades, resulting in fewer replacements and consistent cutting quality over time. The balanced 400 mm diameter and 30-tooth configuration are optimized to deliver smooth material removal while minimizing strain on the power tool motor. Designed for professional workflows, it facilitates precise straight cuts in various wooden workpieces, helping to maintain high productivity on the job site or in the workshop.
Suitable for
Rip cutting and cross-cutting solid wood
General carpentry and woodworking projects
Construction site timber sizing
Workshop furniture making and joinery
When it may not be suitable
This saw blade is not designed for cutting metal, masonry, stone, plastics, or composite materials containing embedded fasteners such as nails or screws, as this may damage the carbide teeth. Additionally, it is not recommended for use with low-power or portable handheld saws that exceed the maximum diameter or speed ratings of a 400 mm blade.
Key specifications
Blade diameter: 400 mm
Bore diameter: 30 mm
Number of teeth: 30
Material: Carbide-tipped steel
Tool compatibility: Professional circular saws
How to use
Ensure the power tool is disconnected from the power source before installing the saw blade. Mount the blade onto the 30 mm spindle arbor, verifying that the rotation direction arrows on the blade match the direction of the power tool rotation. Securely tighten the arbor nut according to the tool manufacturer instructions. Always wear appropriate personal protective equipment, including safety glasses and hearing protection, and verify that the workpiece is firmly clamped before initiating any cutting operation.
What to consider before purchase
Verify that your saw is compatible with a 400 mm blade diameter and a 30 mm bore size
Check the maximum speed rating of your power tool to ensure safe operation
Confirm that the intended application involves wood cutting rather than other materials
Usage recommendations
Always inspect the carbide teeth for wear, cracks, or missing tips before each use, and clean the blade regularly to prevent resin and pitch buildup that can affect cutting efficiency.
