Product Discription
Shank Sizes
We provide Carbide Burr Drill Tools of 6mm (1/4”) and 3mm (1/8”) shank diameter. WUWTOOLS supplies a complete range of 1/4”or 6mm shank burr bits, which are offered in both inch and metric sizes. They are used on air die grinders(pneumatic rotary tools), flexible shafts, spindle grinders, straight grinders, robots, and even CNC machines.
The 3mm or 1/8”shank burr cutters are widely used on metal, wood, glass, stone, and plastics. They fit most hobby rotary tools, such as Dremel, Wen, and Tacklife. These carbide cutters have proven excellent performance in wood carving, model engineering, jewelry making, engraving, sculpting, and casting.
Cut Types of Carbide Burr Drill Tools:
Single-cut burs:are for general purpose work and provide good material removal.
Double-cut burs:produce smaller chips for greater operator control on applications such as stainless steels and ferrous materials.
Aluma-cut burs:have a wide flute design for easy stock removal without loading on applications such as nonferrous and soft materials.
Standard-cut burs:are widely uesed and leave a fine finish.
