Description of Dremel 9909 Tungsten Carbide Cutter: Precision Cutting Tool for Various Materials

The product is 1/8" Diameter, Tungsten Carbide Cutter. Shapes, smooths or grinds especially hard materials including: hardened steel, stainless steel, cast iron, nonferrous metals, fired ceramics, plastics and hard woods. A high-speed cutter made of tungsten carbide, the hardest material next to diamonds. Do not use this cutter for drilling holes or for enlarging holes that are less than twice the diameter of the cutter. The tungsten carbide surface can easily catch the side of a hole and break the bit. For best results, insert the accessory bit all the way into the tool and then back it out slightly before tightening down. This provides plenty of shank for the collet or chuck to hold onto the bit. Secure objects to a stable surface while working.

Excellent tip for fossil preparation

Use this tip for fossil (ammonite) preparation as the tungsten material is strong enough to chip the matrix. Worked great, I think comparable to the narrow tip from ZOIC PaleoTech.

Pros
  • Hole saws
Cons
  • Non-Automatic

Works better than I expected

Used on a stripped and rusty torx bolt on an old jeep. It cut grooves in the studs (appears to be grade 5) easier than I expected (allowing me to use a hammer and chisel). Great purchase and worked very well for what I needed. Used with a drill versus a dremel.

Pros
  • Power Tool Parts & Accessories
Cons
  • Weak

ENGRAVING ONLY……NOT CUTTING

They sound the alarm, but this is my TRUTH! I needed this CUTTER tool badly as the name suggests as I had already been without a car for 30 days as I live in the middle of nowhere and the mobile mechanic didn't even answer my calls or voice messages. So, with no mechanical knowledge/experience, I decided to take on the task of replacing bearings and proceeded to purchase tools for the job. Every time I worked on my car, after a few hours I would buy a new tool and wait for it to arrive just to…

Pros
  • Power and hand tools
Cons
  • Long delivery time
