Product Specification

SF-5 NF TREE SHAPE - RADIUS PREMIUM TUNGSTEN CARBIDE BURR– ¼” shank

SF-5 NF tree shape burrs (also called Rounded Tree Shape) are great for interior contour work and rounded edge processing in small places. Due to the extreme hardness of this tungsten carbide, it can be used on much more demanding jobs than HSS (High-Speed Steel). These carbide burrs are made of tungsten carbide burr die grinder bits and will start to soften at higher temperatures, so carbide is always the best choice for long-term performance.

Aluminum cut carbide burrs tend to be used on non-ferrous metals like aluminum, copper, zinc alloys and magnesium as well as for non-metal materials such as plastics, hard rubber, and some woods. These carbide burrs are specially designed for fast stock removal without loading. Design allows chips to flow out of the flutes. Use for medium stock removal, deburring, finishing, and cleaning.

  • Non-Ferrous Materials – Aluminum, Copper, Zinc alloys, Magnesium
  • Other Materials – Plastic, Hard Rubber, Soft Wood
  • Tree Shape burrs are great for narrow contour work and rounded edge processing in small places.

Safety Tips & Techniques:

  • Tool speed will be determined by the material you are using your burr on. If you are experiencing chipping, you are most likely operating at too high of speed for the application. Start with a slower speed and increase as you go along until you achieve the best results
  • Apply light pressure and let the tool do the work. Bearing down on the tool will result in reduced tool life and a dull burr.
  • Always wear proper PPE to include (but not limited to) safety glasses, hearing protection, respirator, and hand protection.  Keep all guards in place on your machine.
  • Avoid use on electric power drills; the slower speeds can result in chipping of your workpiece.

Customer Reviews (4.8 / 5 · 5 reviews)

Amelia ★★★★★

The ¼” shank fits my rotary tool perfectly, and the tree shape with the rounded end glides through contours without catching. I’ve used it on a few projects already and it holds its edge way better than the cheap bits I had before.

Matthew B. ★★★★★

The rounded tip on this tree-shaped burr makes it much easier to get into tight corners without gouging the material. It leaves a surprisingly smooth finish on aluminum with just a few passes.

Sofia L. ★★★★★

I’ve been using this ¼” shank burr for shaping aluminum and it glides through way faster than my old bits. The rounded tree shape gets into tight spots without catching, and the cut is surprisingly smooth.
