➡️ FAQ - Frequently Asked Questions

❓ 1. When to choose a left-hand thread shaft and when right-hand?

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

This ensures the nut will tighten, preventing it from loosening during operation.

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

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. Cutting dry wood:Linear speed: from 50 m/s to 100 m/sHigher speeds (closer to 100 m/s) are preferred for larger diameter saws and more precise cuts. This facilitates obtaining a smooth cut surface and increases work efficiency.
2. Cutting fresh (wet) wood:Linear speed: from 40 m/s to 70 m/sSpeeds are slightly lower because fresh wood is softer and stickier. Working at a lower speed reduces the risk of jamming, heating, and blade clogging with resin and moisture.

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

❓ 3. How to choose pulleys for the circular saw?

Depending on the diameter of the circular saw blade (including recommended revolutions) and the revolutions of the electric motor – the pulley configuration can vary. Below are some of the most popular configurations for an average linear speed of 55m/s:
