Carbide rotary burrs are used in many industries involved in metal working for cutting and shaping, grinding and removing excess material and sharp edges. They are ideal for deburring, finishing, carving, shaping and smoothing welds, moulds, dies and forgings. Carbide burrs are effectively a rotary file for reshaping and/or dressing material to create a smooth surface finish.
The Ruko high performance tungsten carbide rotary burrs range provide maximum cutting performance and long service life together with excellent stock removal rates and ease of use across popular materials. Tungsten carbide is an extremely hard material which is resistant to high temperatures making it ideal for long term usage.
Tunsten Carbide Rotary Burrs TC
These high performance tungsten carbide rotary burrs have cross toothing which provides a higher cutting capacity when compared with simple toothing. Further more, cross toothing also reduces clogging and ensures precise, effective and reliable results. This particularly has a positive effect on materials which are difficult to cut. These burrs are particularly useful for applications such as high-alloy steels, non-rusting steels, acid-resistant steels, heat-resistant steels, die casts and plastics, for processes such as deburring, breaking edges, trimming, processing welding seams and surface processing. These burrs will leave a smoother finish than the single toothed Aluminium burrs, ideal for medium to light removal of material, deburring, fine finishing, cleannig and creating a smooth finish.
Tungsten Carbide Rotary Burrs Alu
These high performance tungsten carbide rotary burrs have aluminium toothing. These burrs are particularly useful for applications such as non-ferrous metals, aluminium, brass, copper, zinc, diecasts and plastic, for processes such as deburring, breaking edges, trimming and surface processing. These burrs will remove material quickly with a smooth finish, ideal for heavy removal of material, milling, deburring and cleaning.
Toothing for Tungsten Carbide Rotary Burrs
Aluminium toothing is suited to softer materials as it helps prevent the burr becoming clogged up.
Burrs can be coated in Titanium Carbon Nitride which increases surface hardness and heat resistance, offering typically a 30-40% increase in lifespan of tool when compared to the standard burrs.
RUKOs burrs come in a wide range of different shapes, sizes and lengths. Shank size depends on the size of the head, but the most popular sizing is 6mm.
Tungsten Carbide Rotary Burr Shapes
Shape A (ZYA) – Cylinder Without End Cut
A non cutting end means that these burrs are ideal for working on a flat surface or where only one side of corner needs to be worked on.
Shape B (ZYAS) – Cylinder With End Cut
The cutting end allows both sides of a right angled corner to be worked on.
Shape C (WRC) – Oval
The domed end is useful for when cleaning and de-burring holes, it is also ideal for working on corners during fabrication.
Shape D (KUD) – Ball
Ball shaped burrs allow the user to shape and/or hollow out an area, creating a concave cut into the material. These are also useful for shapes involving an overhanging or harder to reach area.
Shape E (TRE) – Teardrop
Used for rounding off corners and concave cutting into the material.
Shape F (RBF) – Ball Nose Tree
Allows concave cutting, also useful for shaping edge welds and chamferring.
Shape G (SPG) – Tree
Used for rounding off corners and concave cutting into the material. The pointed end allows cutting in difficult to access areas and also enables creating of angled corners.
Shape H (FLH) – Flame
Allows concave cutting with a wider flatter channel cut, also useful for shaping edge welds.
Shapes J (KSJ) & K (KSK) – Angled Cones
Useful for accessing angled areas of work, these are ideal for bevelling, counter boring, chamfering and producing countersink holes. These can also be used to de-burr holes.
Shape L (KEL) – Round Cone
Ideal for accessing corners welds in fabrications, rounding edges and surface finishing in difficult to reach areas.
Shape M (SKM) – Cone
deal for accessing corners welds in fabrications in difficult to reach areas, in addition the pointed end allows access to recesses and narrow angles.
Shape N (WKN) – Angled
Used for making v cuts and chamfering.
Recommended Cutting Speeds
Rotary burrs are usually used in a hand held die grinder (electric powered or air tool) as high speed are required – generally greater than 10,000 RPM.
- Let the tool do the work! It is speed of the burr spinning rather than the force applied which removes material. Use a light pressure and multiple passes as this gives more control and reduces wear and tear.
- Try to keep the burr moving constantly in order to prevent it digging into the material causing an uneven or rough surface.
- Always ensure that the burr shank is fixed tightly into your tool as any movement can effect the quality of your work.
- Always wear protection. Parweld offer a variety of eye protection, in addition respiratory protection is also recommended.
Ruko offer a wide range of drilling and cutting tools, Parweld has handpicked a selection of their most popular carbide burrs to stock initially and will continue to add to the range in order to satisfy customer needs.
