Why is the standard T-shank blade holder not suitable for the KRESS SPS 650W saw?

Q: Why is the standard T-shank blade holder not suitable for the KRESS SPS 650W saw?

The KRESS SPS 650W saw uses a quick-change clamping system , which is completely different from a standard T-shank blade holder. This proprietary KRESS system is not compatible with blades that have a standard T-shank holder. The operation of the clamping system is specific: a tension lever rotates to actuate a clamping mechanism that holds the blade without requiring any tools. When you open the tension lever, the blade is released from its mounting point. Conversely, once the blade is inserted, the system automatically creates a 90° clamping angle that only exists on blades designed for this proprietary system. This 90° angle is a safety positioning that ensures a reliable mechanical fixation. Blades compatible with the KRESS SPS 650W must either be original KRESS blades or blades with a maximum thickness of 1.5 mm that conform to the dimension drawing provided in the user manual. This thickness limit is essential: it ensures that the quick-change clamping mechanism can function correctly and hold the blade reliably during operation. Using incompatible blades (notably blades with a standard T-shank holder) presents a serious risk: proper fixation may not be ensured, and the risk of accidents caused by blade detachment would be very high. That is why the manual emphasizes that only original KRESS blades or those conforming to the precise technical specifications should be used. The main advantage of this quick-change clamping system is the speed and convenience of changing blades: you do not need any tools, just turn the tension lever. However, this convenience is only possible if you adhere to the strict compatibility specifications regarding the thickness and type of blade fixation.
