Professional-grade diamond drag engraving bit for CNC routers, mills, and plasma cutters delivers crisp engraved detail on a wide range of materials — including metals (brass, aluminum, steel, stainless steel), glass, stone, granite, and acrylic.
Unlike standard diamond drag bits found on Amazon, this 1/4" shank industrial-grade CNC engraving bit is trusted by major manufacturers — including Campbell’s Soup, General Motors, and NASA — for high-precision engraving.
Designed for any CNC machine with X, Y & Z motion — including CNC routers, CNC milling machines, and CNC plasma cutters — this CNC engraving bit produces clean engraved lines. Its spring-loaded “floating head” applies consistent pressure to the diamond tip, automatically compensating for warped materials or imperfect tables.
How it works:
Includes everything you need to start engraving:
For coated materials (such as lacquered brass or anodized aluminum name tags) and fine detail work (tiny lettering or thin materials under 0.030” thick), we recommend using the optional 90° diamond tip (sold separately).
Recommended feed, speed, and depth settings are included with your engraving bit.

Awesome drag bit. Works great.
Can wait to see what happens but nothing yet
this bit works great
The WidgetWork diamond drag bit comes with detailed instructions for settings that works flawlessly. Bit seems a bit pricey, but replacement bits are reasonably priced.
As a novice beginner, messing around my first attempt using the 120 degree tip on glass turned out better than expected. IDC has rocked with quick service filling my orders. Highly recommend IDC 100%!
Wow, I was so delighted with every aspect of my purchase. Garett and the team go above and beyond all my expectations! 110% would recommend! Thanks so much guys.
