Bosch 2 608 644 121 circular saw blade 16 cm 1 pc(s)

The Bosch 2 608 644 121 circular saw blade is a 160 mm diameter blade with a 20 mm bore designed specifically for cutting cement fibre panels. Sold as a single unit, the blade is intended for use with compatible circular saws and provides a balance of cut quality and service life when working with dense, fibrous building boards. The blade geometry and material selection focus on controlled chip removal and reduced edge chipping for cleaner cuts in cement-based panel materials.

Advantages

This circular saw blade offers precise cutting performance on cement fibre panels while maintaining good durability under continuous use. The tooth design reduces splintering and ensures straighter cuts, which helps minimize post-cut finishing. Being a single-piece supply makes it convenient for quick replacement and inventory control for tradespeople and professionals.

How to use

Mount the blade on a circular saw that accepts a 20 mm arbor and 160 mm diameter blades, ensuring the saw is disconnected from power before installation. Tighten the blade flange according to the saw manufacturer's torque recommendation and confirm the blade rotation direction matches the saw guard marking. When cutting cement fibre panels, support the panel firmly, use steady feed speed to avoid overloading the blade, and allow the blade to come up to full speed before contacting the material. After cutting, inspect the blade for wear or damage and replace it if teeth show excessive wear or chipping.

Recommendations

Use appropriate personal protective equipment including eye protection, dust mask or respirator rated for cement dust, hearing protection and gloves. For improved dust control and longer blade life, cut with dust extraction or a vacuum system and avoid forcing the blade through the material. Follow the circular saw manufacturer's instructions for safe operation and blade selection.
