Hoja de sierra circular Bosch 2 608 644 139

The Bosch 2 608 644 139 circular saw blade is a 190 mm diameter blade with a 30 mm bore designed for cutting construction-grade wood. Engineered for compatibility with standard circular saws, it provides even cutting performance for crosscuts and rip cuts in timber, softwood, plywood and similar panel materials. Supplied as a single blade, it is intended for use where reliable, repeatable cuts are required on job sites or in a home workshop.

Advantages

The blade features a tooth geometry optimized for clean edges and reduced splintering on wood surfaces. Balanced construction minimizes vibration during operation, contributing to smoother cuts and improved control. Its hardened cutting edges retain sharpness under normal woodworking conditions, extending usable life between replacements. The 190 mm diameter and standard 30 mm bore ensure wide compatibility with many circular saw models.

How to use

Install the blade on a compatible circular saw following the saw manufacturer's instructions, ensuring correct orientation of the teeth. Tighten the arbor flange securely and verify blade guard operation before powering the tool. Use appropriate feed rates and cutting speed for the material being cut, and allow the blade to reach full speed before engaging the workpiece. Replace the blade when cutting performance or edge quality declines.

Recommendations

Always wear eye and hearing protection and use push sticks or guides for safe, controlled cuts. Match blade RPM and tooth type to the material and cutting method for best results. Regularly check blade balance and flange torque to maintain cut quality and reduce strain on the saw.
