RDZ Engraving Diamond, Spring Loaded CNC Machine Drag Engraving Tool (3 Pack)

I bought these to use for engraving with a Shark CNC machine. I've used them mostly on jewelry - sterling silver and aluminum key chains. They work great for what I need them for and are able to engrave on really small items which is amazing to me.

Miniature etching and engraving with a CNC router rin acrylic is challenging if you don't have a 40W+ CO2 laser machine.This bit solved the issue with amazing results. I will post a video to show the quality of the workThe bits arrived in less than 3 days even they are no Amazon prime.

Exactly what I needed. Work great when engraving brass.

Used the 90D to engrave glass, it worked well however it didn't last long on lead crystal.

bits work good, just as expected. delivery was quick.

I ordered the 3 pack. I received 2 are broken and one was good.

These bits will take your CNC router to a new level. I was engraving two color plastic identification placards for electrical panels. I had purchased some high quality aluminum blanks for special use and I wasn't getting the desired results with a spindle and bit. I bought these diamond tipped bits, they go into the spindle motor but you don't turn on the spindle, it's a drag bit. OMG, I was blown away by the results, I wasn't expecting this level of detail, and I was using the 120 degree bit in this photo. To bad the software I am using has an issue generating G-Code for certain characters, I need to remake this placard.
