Common Symptoms And First Checks

Problem Possible Cause Useful Evidence
Heavy burrs Wrong tooth pitch, dull blade, unstable feed or weak clamping Cut surface photo and tube wall thickness.
Broken teeth Impact load, wrong tooth count, vibration or material hardness change Broken tooth photo and cutting video.
Short blade life Wrong coating, speed, coolant, material mismatch or poor chip removal Current blade data and production quantity.
Rough surface Runout, body rigidity, feed instability or unsuitable tooth form Surface photo and machine model.

What We Need To Diagnose

Send the current blade size, blade photo, machine model, material grade, workpiece size, wall thickness, coolant condition, daily cutting quantity and photos or videos of the problem.

When To Change Blade Type

If repeated adjustments do not solve the problem, the application may need a different blade family, coating, carbide grade, tooth count or kerf. This is why GF, HSS, TCT and cermet blades should be compared by real cutting condition.
