Specifics You Need To Be Informed About Carbide Burrs

Carbide Burrs (also called Rotary Burrs) can be used cutting, shaping, grinding but for the eliminating sharp edges, burrs and excess material (deburring).

1. What material can Carbide Burrs be utilized on?
Carbide burrs works extremely well on many materials. Metals including steel, aluminum and iron, all kinds of wood, acrylics, fibreglass and plastics. When utilized on soft metals such as gold, platinum and silver, carbide burrs are great while they can last quite a while without having chipping or breaking.

Steel, Carbon Steel & Stainless Steel
Gold, Platinum & Silver
Plastic, Carbon fibre Reinforced Plastic (CRP), Glass Fibre Reinforced Plastic (GRP)
Brass, Copper & Bronze
Different cuts of carbide burrs will probably be suitable to certain materials, see the next point below to discover more on the various cuts.

So what can You utilize Carbide Burrs In?
Ideally carbide burrs are used in Air Tools i.e Die Grinders, Pneumatic rotary tools and speed engravers. Micro Motors, Pendant Drills, Flexible Shafts, and hobby rotary tools like a Dremel.

Only use a handpiece that runs true i.e without wobble.

Who Uses Carbide Burrs?
Carbide burrs are traditionally used for metalwork, tool making, engineering, model engineering, wood carving, jewellery making, welding, chamferring, casting, deburring, grinding, cylinder head porting and sculpting. And are employed in the aerospace, automotive, dental, metal sculpting, and metal smith industries to mention but a few.

2. Carbide Burrs Commonly Appear in Two Cuts; Single Cut and Double Cut (Diamond Cut)
Single cut (one flute) carbide burrs use a right handed (Up cut) spiral flute. These are generally used in combination with metal, hardened steel, copper, cast iron, and ferrous metals and definately will remove material quickly with a smooth finish. Use for heavy stock removal, milling, deburring and cleaning.

Heavy elimination of material
Creates long chips

Double cut carbide burrs are generally used on ferrous and non ferrous metals, aluminium, soft steel and also for all non-metal materials for example plastics and wood. They’ve got more cutting edges and will remove material faster. Double cut are sometimes referrred to as Diamond Cut or Cross Cut (2 flutes cut across each other) leaves a smoother finish than single cut because of producing smaller chips while they cut away the information. Use for medium-light stock removal, deburring, finishing and cleaning. A dual cut carbide burr is regarded as the popular cut and will see you through most applications.

Medium- light removing material
Fine finishing
Smooth finish
Creates small chips

3. What Speed or RPM the use of your Carbide Burrs?
The velocity from which you have your carbide bur inside your rotary tool is determined by the pad you use it on and the contour being produced but it is reliable advice you do not need to exceed speeds of 35,000 RPM.

4. Do Not Apply Too Much Pressure
As with all drill bits and burrs, allow burr perform the work and apply only a little pressure otherwise the cutting edges from the flutes will chip away or become smooth too quickly, reducing the life of your burr.

5. Carbide Burrs are not as easy Than HSS Burrs
Our Carbide Burrs are machine ground from the specially chosen grade of carbide. Due to the extreme hardness with the Tungsten Carbide they can be used on much more demanding jobs than HSS (High-speed Steel).

Carbide Burrs also perform better at higher temperatures than HSS so that you can run them hotter, as well as for longer.

HSS burrs will begin to soften at higher temperatures so carbide is always a better choice for lengthy term performance.

What Are The Features of Tungsten Carbide Burrs?
Use for long production runs
High stock removal
Suitable for using on many hard and difficult materials
Ideal for Deburring, finishing, carving, shaping and smoothing welds, moulds, dies and forgings

6. Keep The Carbide Burr On the road
When you use your carbide burr try not to keep it still for days on end since this prevents the burr from digging and jabbing into the material causing unsightly marks and roughness.

End by using an ‘up’ stroke for the smoother finish on your work.

Stay Safe:
Always keep your burr shank is well inserted to your collet and clamped down tightly
Keep pressure light whilst the bur moving, centering on the very best material first
Be sure that your effort is secured tightly on your workbench
Don’t snag or jam your burr to your work
Wear eye protection at least, but on top of that utilize a full shield for the face
