Burrs
Rotary burrs are precision-ground tools designed for cutting, shaping, grinding and deburring metal, plastic or wood. Ideal for use in die grinders, multi-tools and drills, they offer clean removal of burrs, weld splatter, sharp edges and casting flash.
What Are Burrs Used For?
Essential for metal shaping and finishing work:
- Deburring – Remove sharp edges and ridges on machined or cut parts
- Weld Cleanup – Grind and blend weld beads on structural or decorative work
- Metal Shaping – Carve or groove in alloy, cast iron or steel surfaces
- Surface Prep – Smooth, chamfer or countersink parts before painting or joining
Used By:
- Fabricators and machinists
- Welders and M&E professionals
- Metal sculptors, model builders and custom auto workers
Choosing the Right Burr
Shape, cut and material all matter:
1. Burr Shape
Cylindrical, ball nose, flame, cone or oval — each offers control over cut type and access.
2. Material
Carbide burrs are most common — ideal for steel and alloy. Aluminium cut burrs reduce clogging on softer metals.
3. Shank Size
Check your grinder or rotary tool accepts 3mm, 6mm or 1/4" shanks depending on chuck or collet.
Rotary Burr FAQs
What’s the best burr for steel?
Use carbide burrs with standard or double cut for effective shaping and long life. Avoid aluminium cut burrs which clog on harder metals.
Can I use these in a cordless drill?
Yes — as long as the shank fits the chuck. However, rotary tools or die grinders give better speed control and precision.
What’s the difference between single cut and double cut?
Single cut removes material quickly. Double cut offers smoother control and reduced chatter — ideal for curved surfaces and finer work.
Do these work on stainless steel?
Yes — carbide burrs are ideal for stainless steel. Use light pressure and consistent motion to avoid heat build-up.
