The blades of all Z-Saws are made from polished cold rolled high carbon steel strips which we source from prestigious manufacturers in the international market under strict quality control. The steel strips are as hard as HV 540 to 580 with 0.8 -0.9 % of carbon content , widely considered to be the best material for high quality saw blades featuring superb flexibility and durability.
The teeth of Z-Saw blades are ground using our self-developed automatic tooth grinding system using CBN grinding wheels. Even the smallest distortion will be automatically detected and carefully corrected. Through this process, the blades can be ground to perfectly parallel edges , ensuring that the teeth bite into the workpiece completely straight. This is almost impossible to achieve with hand-filed teeth.
Z-Saw makes saw blades with several different basic tooth patterns (e.g. rip / cross / universal) each of which is applied to different saw blades with subtle variations depending on the use of each individual saw.
All the teeth of Z-Saw branded blades are hardened through the “Hard Impulse” treatment to increase the degree of hardness to the level of HV800-950 (64.0 - 68.2 HRC), which is the maximum hardness which can be achieved on steel. Implementing this treatment on the tips of the saw teeth means that they are able to stay sharp much longer than conventional counterparts while the core of the blade remains both flexible and tough to prevent bending or buckling during use.
