1060 – 07 – Gullet & Gullet Capacity

1m

Another important variable crucial to proper cutting is gullet capacity. The rounded area between the teeth on a blade collects chips as the blade passes through the material. This is called the gullet. When the tooth scrapes away material during the cut, the chip curls into the area. A proper clearance allows the chip to curl up the same way into the gullet and fall away as the blade clears the material.

When too much material is scraped away, the gullet area overflows, deforms, and can stick which causes resistance. This can cause the machine to become impaired, even causing the blade to bounce and become damaged. It also wastes energy. Each tooth has to clear the workpiece and get rid of its chip load. If the gullet overfills, the cip becomes deformed. Proper tooth pitch selection using our blade selector table in Sawblade.com will help you choose which tooth pitch is right for you.
