The Summa knife holder is a specialized fixture for imported high-end engraving machines, which is only compatible with the Saint Ma machine and cannot be interchanged with the Mimark and Roland knife holders. The blade body is made of aviation aluminum alloy, with a hardened surface and high-precision micro bearings installed inside. The rotational concentricity is extremely high, and there will be no shaking or rounded corners during long-term high-speed cutting.
The tail of the blade holder is equipped with a rolling locking knob, which can freely control the extension length of the blade. The conventional extension amount is controlled within 0.5 millimeters, which can cut car stickers and reflective films without scratching the bottom paper. It can hold the full range of Saint Ma tungsten steel blades at 30 °, 45 °, and 60 °, with sharp lines, no burrs, and no trailing when cutting small characters and complex hollow patterns.
The biggest advantage of this knife holder is its strong stability, suitable for batch processing of high-end materials such as 3M reflective film and heat transfer film. The bearings are smooth, durable, and easy to maintain. Regularly adding a small amount of lubricating oil can extend their service life. It has become a standard accessory for advertising signage and traffic sign processing due to its ultra-high cutting accuracy.
