Facts It’s Important To Find Out About Carbide Burrs

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

1. What material can Carbide Burrs provide on?
Carbide burrs can be used on many materials. Metals including steel, aluminum and certain, all types of wood, acrylics, fibreglass and plastics. When applied to soft metals like gold, platinum and silver, carbide burrs are perfect since they can last quite a long time without any chipping or breaking.

Steel, Carbon Steel & Stainless-steel
Cast Iron
Gold, Platinum & Silver
Plastic, Carbon fibre Reinforced Plastic (CRP), Glass Fibre Reinforced Plastic (GRP)
Brass, Copper & Bronze
Different cuts of carbide burrs is going to be suitable to particular materials, start to see the next point below to discover more on the several cuts.

What Do 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 trusted for metalwork, tool making, engineering, model engineering, wood carving, jewellery making, welding, chamferring, casting, deburring, grinding, cylinder head porting and sculpting. And so are used in the aerospace, automotive, dental, metal sculpting, and metal smith industries to mention just a few.

2. Carbide Burrs Commonly Come 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 with metal, hardened steel, copper, iron, and ferrous metals and will remove material quickly which has a smooth finish. Use for heavy stock removal, milling, deburring and cleaning.

Heavy eliminating material
Creates long chips

Double cut carbide burrs are generally applied to ferrous and non ferrous metals, aluminium, soft steel and for all non-metal materials like plastics and wood. They have more cutting edges and will remove material faster. Double cut are often 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 as they cut away the pad. Use for medium-light stock removal, deburring, finishing and cleaning. A dual cut carbide burr is easily the most popular cut and can see you through most applications.

Medium- light elimination of material
Fine finishing
Smooth finish
Creates small chips

3. What Speed or RPM the use of your Carbide Burrs?
The velocity of which you employ your carbide bur with your rotary tool is dependent upon the pad you use it on along with the contour being produced but it is safe to assume you don’t need to exceed speeds of 35,000 RPM.

4. Do Not Apply An excessive amount of Pressure
As with every drill bits and burrs, allow burr perform the work and apply only a little pressure otherwise the cutting edges of the flutes will chip away or become smooth too soon, lowering the use 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. Because of the extreme hardness of the Tungsten Carbide they could be applied to much more demanding jobs than HSS (Broadband Steel).

Carbide Burrs also perform better at higher temperatures than HSS to help you run them hotter, as well as longer.

HSS burrs are going to soften at higher temperatures so carbide is definitely a more sensible choice for lengthy term performance.

Do you know the Features of Tungsten Carbide Burrs?
Long life
Use for lengthy production runs
High stock removal
Suitable for using on many hard and tough materials
Ideal for Deburring, finishing, carving, shaping and smoothing welds, moulds, dies and forgings

6. Maintain your Carbide Burr On the road
When using your carbide burr do not ensure that it stays still for days simply because this will prevent the burr from digging and jabbing into the material causing unsightly marks and roughness.

End with an ‘up’ stroke for any smoother finish to your work.

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