Start With Machine Fit
Before discussing material or tooth count, confirm the machine model, blade outer diameter, bore size, pin holes and blade thickness. Many GF / SL style blades use a 16mm bore, but the final fit should always be checked against the machine or current blade.
Match Tooth Count To Tube Wall Thickness
Thin-wall stainless steel tube usually needs finer teeth to reduce grabbing and burrs. Thicker wall tube needs more chip space, so a lower tooth count is often more stable. For example, common SL series references include 63mm, 68mm and 80mm blades with tooth counts such as 100T, 72T, 44T, 34T and 80T.
Check The Cutting Result
If the tube end has burrs, vibration or uneven marks, the cause may be wrong tooth pitch, dull blade, unstable clamping, unsuitable feed or poor chip removal. A photo of the cut surface and a short cutting video are very useful for diagnosis.
