(New & Improved tip for longer life) We have been working with our diamond tip manufacturer to make a tip that will last longer. They have improved the process which makes a better quality tool) 1/4" DIAMOND DRAG ENGRAVING TOOL WITH 90° TIP This is a brand new spring loaded drag engraving tool with a 90 degree diamond tip. (See the diagram to show the actual angle of the tool) Many people are confused by what angle you are actually getting. I drew the sketch to help clarify the tool. It can be used on any engraving machine that has a 1/4" collet. With this type of tool you are able to do very detailed engravings on uneven surfaces and the engraving remains even. The tool does not rotate so you do not need to run the spindle. These are perfect for engraving several types of material including brass, aluminum, fiber board, acrylic, plastic painted surfaces and much more. The tool has a precision ground 1/4" diameter stainless steel body with an 1/8" diamond bit that extends out by approximately 1/2", the overall length is approx. 2" & there is up to 3/8" travel. These are made in our own machine shop by skilled machinists & each one is inspected and tested before packaging. Dont be fooled by our low price, these are high quality tools made in the USA on CNC machines. If you have any questions please contact us before buying. Thanks for looking and Happy Engraving!
