Cut-off decisions: cut face quality, blade life, length tolerance, tracking and cold saw versus friction saw.
Lengths that wander by a few millimetres are rarely a blade problem. Three subsystems decide cut length — measurement, clamping and tracking — and each fails in a recognisable way.
If blade consumption is eating your margin, the answer is rarely a different blade brand. Seven variables decide how many cuts a blade gives — and six of them are set on your machine.
The cheap cut-off is rarely the cheap decision. A comparison of cold saw and friction saw on cut quality, secondary operations, blade cost, noise and what each one does to the tube end.
