The Alphacool pit saw for acryl/PETG tubes is no ordinary saw from the hardware store. Its special saw blade with fine teeth makes it perfectly suited for cutting acryl/PETG tubes. This saw blade eliminates the usual problems. Even when first placed against the tube, the teeth cut through the acryl so smoothly that there is no slipping around. Any breaking or ripping of the tube at the last few cuts is also eliminated, thanks to the fine saw teeth. It's a familiar problem: you want to make a straight cut with the saw, but because of the thin saw blade, every cut you make gets a little more crooked?! Not an issue here. This saw blade is just thick enough not to tilt, but still thin enough to get a precise cut. With Alphacool's pit saw, every cut is neat and straight, down to the last pull.
