1/4'' Shank 6.35 mm Dia Double Cut Solid Carbide Rotary Burr Porting Tools Carbide Burrs

  For heavy-duty applications in shipyards, foundries and steel structures, Union Carbide has developed two new special cutting methods for its carbide burrs.

  The new 3R and 3RS cutting edges represent a new cemented carbide product line specifically designed for harsh working conditions. These tungsten carbide burrs are characterized by excellent impact resistance and performance. The new cut is ideal for all applications involving high mechanical shock or impact loads. Effectively reduce the possibility of tooth cracking/breaking, chipping and burr cracking. Even if only a medium-power machine is used to mill at a low RPM, the occurrence of tooth damage can be significantly reduced.
As with all other carbide burrs, our 3R and 3RS cutting types stand out with perfectly matched tooth shape, number of teeth, helix angle, rake angle and concentricity. Because they have a high destocking capability throughout their service life, these tools can provide excellent results in the shortest time.

  The new 3R and 3RS cutting edges are the latest products in the existing cemented carbide series. They cannot replace our mature universal burr standard cutting products. Complete tungsten carbide burr production line.

The Carbide Rotary Burrs is a effective way to realize mechanization in hand workoperations.In the industries of airplane,,ship building,automoble,machinery,

chemistry etc.Carbide Rotary Burrs can be widely used in machining iron,steel casting,carbon steel,alloy steel,stainless steel,hardened steel,copper aluminium etc.

Machining various kinds of metal material including ≤HRC65 hardened steel.

Instead of small emery wheels,without powder pollution.

1.Increasing productivity of several ten times than using hand tools and three to five times than using small emery wheels

2.Having long life of ten times than high speed steel burrs and fivty times than small emery wheels.

3.Finish machining various kinds of die cavities.

4.Removing the burrs of the castings,forgings and the welding spatter on the weld assemblies.

5.Chamfering angle,circular bead or flute on the mechanical components.

6.Chamfering or burring the pipes.

7.Polishing the impeller channel.

8.Grinding the hole to an accurate shape.
