产品详细说明：

Kennedy variable pitch bi-metal high speed holesaws feature a very aggressive cutting action, which gives a very smooth finish and substantial reductions in noise levels. Noise reduction is achieved by disrupting the harmonics produced when sawing certain materials and structures such as tubing and angle. An improvement in swarf clearance is also achieved.
Cutting Depth: 28.5mm (1.1/8").

For use with arbors K1 & K4.
