➡️ FAQ - Frequently Asked Questions

❓1. When to choose a shaft with a left-hand thread versus a right-hand thread?

• Choose a left-hand thread if the circular saw blade should rotate clockwise (looking from the nut side).
• Choose a right-hand thread if the circular saw blade should rotate counterclockwise (looking from the nut side).

This ensures the nut tightens, preventing loosening during operation.

❓2. What should the linear speed of the circular saw be?

The recommended linear speed for circular saws for wood cutting depends on the type of wood (dry or fresh) and the specifications of the blade itself. Generally accepted values are:

1. Dry wood cutting: Linear Speed: from 50 m/s to 100 m/s Higher speeds (closer to 100 m/s) are preferred for larger diameter saws and more precise cuts. It facilitates obtaining a smooth cutting surface and increases work efficiency.
2. Fresh (wet) wood cutting: Linear Speed: from 40 m/s to 70 m/s Speeds are slightly lower because fresh wood is softer and stickier. Working at a lower speed reduces the risk of jamming, heating, and clogging of the blade by resin and moisture.

These speeds may vary depending on the type of machine, blade material, teeth number, and shape. It is also important to follow the manufacturer’s recommendations for the circular saw and machine to ensure safe and efficient cutting.

❓3. How to select pulleys for a circular saw?
