Product Description

Spring loaded sliding diamond tip drag engraver can engrave on most substantially stiff materials from plastics to glass, metals and stone (other than diamond). To use, install into a 1/2″ collect on your milling machine spindle or router, engage the diamond tip to the material and then move the spindle an additional 1/8″ closer to the material. Doing so compresses the preload spring ensuring the diamond tip is in constant contact with the surface being engraved. Next run your CNC engraving program with the spindle off. Because the diamond tip is telescoping uneven surfaces are evenly engraved eliminating faded characters or over engraved characters. We have engraved hardened steel at 100 ipm! (see our YouTube video under Exact Engineering, LLC). Cutting engravers cannot compete! We recommend the stiff spring for metals and hard plastics and the soft spring for glass like materials and a starting compression of 1/8″. The engraving groove width/depth can be tailored by simply changing the amount of tip compression and or spring or both. Proudly engineered and made in the USA!
