Burr-Free Tube Cutting
Tooth Count and Tooth Geometry for Burr-Free Steel Tube Cutting
How to choose saw blade tooth count, tooth pitch, gullet capacity and tooth geometry for cleaner steel tube cutting with less burr.

Search intent: A buyer or engineer wants to know whether tooth count is causing burrs in tube cutting.
Steel tube cutting is interrupted cutting. The blade enters a curved surface, cuts through one wall, crosses the hollow section and exits another wall.
If too few teeth are engaged, the blade hammers the wall. If too many teeth are engaged, chips pack in the gullets and the blade rubs.
Tooth count is a cutting condition, not only a catalog number. It must keep enough teeth in the tube wall while leaving enough chip space to avoid heat and burrs.
Thin-wall tube needs stable tooth engagement
Thin-wall tube is easy to deform and vibrate. A finer pitch, stable blade body and controlled feed help keep the tube round and reduce the inside burr at exit.
Kinkelder’s thin tube application connects thin-wall cutting with stable clamping, low cutting force, reduced torque and dedicated saw blade design.
Thick-wall pipe needs chip space
Heavy-wall pipe and solids produce larger chips. If tooth count is too high, the gullets fill before the tooth leaves the cut, creating heat, rough surface and burr.
For these applications, stronger tooth geometry and larger chip capacity may matter more than a high tooth count.
Real public example: multi-tube cutting
Kinkelder's KINS' BLUE Multi is positioned for cutting multiple steel tubes where stability, clamping and complex geometry are difficult. The public product page highlights TCT tooth design, PVD coating and chip evacuation.
That example supports a practical message: tube geometry and holding method decide the tooth count more than the blade diameter alone.
Application table
| Application | Tooth direction | Reason |
|---|---|---|
| Thin-wall round tube | Higher tooth count / finer pitch | Keeps more teeth in the wall and reduces tooth shock. |
| Square tube | Application-specific pitch and stable geometry | Corner entry creates interrupted engagement and vibration risk. |
| Thick-wall pipe | Lower tooth count than thin tube | Large chips require gullet space. |
| Multiple tubes | Special multi-tube blade geometry | Uneven engagement and clamping make chip control harder. |
Recommended blade direction
For thin-wall carbon steel tube, use Ciswerk TCT Cold Saw Blade or Ciswerk HSS Circular Saw Blade with higher tooth count and stable body design. For medium-wall tube and profile, use Ciswerk Cermet Cold Saw Blade or Ciswerk TCT Cold Saw Blade based on tensile strength, RPM and coolant.
FAQ
How many teeth should a steel tube blade have?
There is no universal number. Start from blade diameter, tube OD, wall thickness, material grade, saw type and required teeth in the cut.
Can one blade cut tube and solid bar?
Sometimes, but tube and solid cutting have different chip evacuation and tooth engagement requirements.
