Carbide Burrs

Carbide burrs (rotary files) grind, shape and deburr metal at die grinder speeds. The range leans on Josco Garryson: diamond cut burrs in cylinder, ball nose cylinder, tree and cone profiles, steel-cut ball nose tree burrs and aluminium cut patterns for soft, gummy metals — with double cut, aluminium cut and boxed set subcategories below.

Fabricators and maintenance fitters use them for weld dressing in tight corners, enlarging holes, chamfering cut edges and porting where a grinding disc can't reach.

Which burr shape does what?

• Cylinder: flat surfaces and edge work.
• Ball nose cylinder: contoured surfaces plus fillets in one burr.
• Tree: access into acute angles and weld toes.
• Cone: countersinking and V-shaped grooves.
