OOLS & HARDWARE
Variable pitch bi-metal high speed steel holesaws have a very aggressive cutting action. This disrupts the harmonics produced when sawing certain materials and structures such as tubing angle etc. A very smooth finish and substantial reductions is noise levels result from using variable pitch holesaws.
An improvement i swarf clearance is also achieved. 28.5mm (11/8") cutting depth.
