How long your blade lasts is influenced by the conditions listed below.
If the conditions are not satisfied, blades last for notably less time and problems can occur.


1) Material
– The final and initial parts of the bars are often thinner so the vices do not hold them well. This means the workpiece can move, which
ruins the blade teeth. When working on the ends, be very careful and cut a part to the longest length possible.
– The piece should always be straight and even.
– The material should be untreated; if hardened, the blade will not last as long.

2) Machine
– The machine must be suitable for TCT blades, machines for HSS blades are different.
– The blade brush must work well.
– The lubricant must be suitable.
– The blade locking flanges must be correct and in excellent condition.
– The clamps that hold the piece must not be damaged.
– The closing force of the vices must be suitable.
– The blade guides must be at the correct distance from the blade.
– The jet of lubricant must be positioned correctly.
– The gears must not make strange noises.
– Check the V-belt; if damaged or broken the teeth will chip immediately.

3) Operators must make sure that
– the machine conditions are appropriate.
– the work parameters are correct.
– the number of teeth is correct for the material thickness.
– the type of blade is right for the material.
– the material thickness does not change.
– the blade type and specifications are correct.
– the blade finish is in tolerance.
– the teeth are not chipped, damaged or discoloured.
