Points It Is Advisable To Be Informed On Carbide Burrs





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

1. What material can Carbide Burrs be used on?
Carbide burrs may be used on many materials. Metals including steel, aluminum and cast iron, all types of wood, acrylics, fibreglass and plastics. When suited for soft metals like gold, platinum and silver, carbide burrs are great since they can last quite a long time without having chipping or breaking.


Steel, Carbon Steel & Stainless Steel
Certain
Aluminium
Titanium
Cobalt
Nickel
Gold, Platinum & Silver
Ceramics
Fibreglass
Plastic, Graphite Reinforced Plastic (CRP), Glass Fibre Reinforced Plastic (GRP)
Brass, Copper & Bronze
Zinc
Wood
Different cuts of carbide burrs will probably be ideal to a particular materials, see the next point below to find out about the different cuts.

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

Use a handpiece that runs true i.e with no wobble.

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

2. Carbide Burrs Commonly Appear in Two Cuts; Single Cut and Double Cut (Diamond Cut)
Single cut (one flute) carbide burrs possess a right handed (Up cut) spiral flute. These tend to be combined with metal, hardened steel, copper, cast iron, and ferrous metals and may remove material quickly with a smooth finish. Use for heavy stock removal, milling, deburring and cleaning.

Deburring
Cleaning
Creates long chips

Double cut carbide burrs usually are suited for ferrous and non ferrous metals, aluminium, soft steel as well as for all non-metal materials such as plastics and wood. They've got more cutting edges and will remove material faster. Double cut are occasionally referrred to as Diamond Cut or Cross Cut (2 flutes cut across one another) leaves a smoother finish than single cut as a result of producing smaller chips while they cut away the information. Use for medium-light stock removal, deburring, finishing and cleaning. A double cut carbide burr is the most popular cut and can help you through most applications.

3. What Speed or RPM if you work with your Carbide Burrs?
The velocity from which you have your carbide bur inside your rotary tool is determined by the fabric you're using it on and the contour being produced yet it's safe to assume you don't to exceed speeds of 35,000 RPM.

4. Do Not Apply An excessive amount of Pressure
As with all drill bits and burrs, let the burr perform work and apply merely a little pressure otherwise the cutting edges of the flutes will chip away or become smooth prematurely, decreasing the life span 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. As a result of extreme hardness from the Tungsten Carbide they may be used on a lot more demanding jobs than HSS (High-speed Steel).

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

HSS burrs will quickly soften at higher temperatures so carbide is usually a better option for too long term performance.

What are Advantages of Tungsten Carbide Burrs?
Longevity
Use for very long production runs
High stock removal
Ideal for using on many hard and difficult materials
Perfect for Deburring, finishing, carving, shaping and smoothing welds, moulds, dies and forgings

6. Maintain your Carbide Burr Moving around
When utilizing your carbide burr don't ensure that it stays still for days on end because this minimizes the burr from digging and jabbing in your material causing unsightly marks and roughness.

End while on an 'up' stroke for a smoother finish on your work.

Stay Safe:
Always keep your burr shank is well inserted into the collet and clamped down tightly
Keep pressure light and make the bur moving, centering on the highest material first
Be sure that your work is secured tightly to your work bench
Don't snag or jam your burr to your work
Wear eye protection as a minimum, but better still work with a full shield for the face
