The Perfect Burr for Hollowing and Contouring

When you need to hollow out a workpiece, create a concave profile, or deburr the inside of a pipe, a flat burr just won't cut it. The UCT Gem Carbide SD-3 is a 3/8" ball-shaped burr designed for exactly that. Its "double cut" (cross-cut) flutes give you smooth, controllable grinding and a finer finish, breaking down tough steel and cast iron into small, manageable chips.

Key Features

  • Double-Cut Head: Produces small chips for smooth operation and a finer finish. Ideal for ferrous and non-ferrous metals.
  • Ball Shape (SD-3): Perfect for hollowing, creating concave profiles, and deburring the inside of pipes or holes.
  • Solid Tungsten Carbide: Made from one solid piece of carbide for maximum rigidity, high-heat tolerance, and a long cutting life.
  • 1/4-Inch Shank: The industry standard shank, compatible with most 1/4-inch die grinders and rotary tools.
  • Versatile Application: Makes quick work of deburring, shaping, porting, and contouring on steel, cast iron, and aluminum.

Great Travel Q-Tips in Sturdy Reusable Container
Size: 30 Count (Pack of 1)
Great travel pack of the best brand on the market Q-Tips and can easily be refilled and used over and over. I thought maybe after 10 plus years it was time to buy another one for our trips, very durable and the Q-Tips brand is the only brand with soft real cotton tips that are thick enough that they don’t hurt your ears. Great price and delivered quickly.

Perfect for Travel and Everyday Use
Size: 30 Count (Pack of 1)
These Q-tips are the same great quality as the regular ones, just in a smaller, travel-friendly pack. The cotton tips are soft and sturdy, and they don’t unravel like cheaper brands. The compact container fits perfectly in my toiletry bag or purse, so it’s super convenient for trips or quick touch-ups on the go. I use them for everything — cleaning small areas, makeup fixes, and first aid. It’s nice knowing they’re 100% cotton and gentle on the skin. Great little pack to keep around for travel or your car!
