Points You Have To Have Knowledge Of Carbide Burrs

Carbide Burrs (often known as Rotary Burrs) are used for cutting, shaping, grinding and for the removal of sharp edges, burrs and excess material (deburring).

1. What material can Carbide Burrs supply on?
Carbide burrs may be used on many materials. Metals including steel, aluminum and surefire, all types of wood, acrylics, fibreglass and plastics. When used on soft metals like gold, platinum and silver, carbide burrs are ideal because they can last a very long time without chipping or breaking.

Steel, Carbon Steel & Stainless Steel
Surefire
Aluminium
Titanium
Cobalt
Nickel
Gold, Platinum & Silver
Ceramics
Fibreglass
Plastic, Carbon Fiber Reinforced Plastic (CRP), Glass Fibre Reinforced Plastic (GRP)
Brass, Copper & Bronze
Zinc
Wood

So what can You employ Carbide Burrs In?
Ideally carbide burrs are employed 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 having 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 so are used in the aerospace, automotive, dental, metal sculpting, and metal smith industries to only a few.

2. Carbide Burrs Commonly Can be found in Two Cuts; Single Cut and Double Cut (Diamond Cut)
Single cut (one flute) carbide burrs have a right handed (Up cut) spiral flute. These tend to be used with stainless, hardened steel, copper, certain, and ferrous metals and can remove material quickly using a smooth finish. Use for heavy stock removal, milling, deburring and cleaning.

Heavy elimination of material
Milling
Deburring
Cleaning
Creates long chips

Double cut carbide burrs are usually applied to ferrous and non ferrous metals, aluminium, soft steel and also for all non-metal materials like 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 on account of producing smaller chips since they cut away the information. Use for medium-light stock removal, deburring, finishing and cleaning. A dual cut carbide burr is among the most popular cut and may view you through most applications.

Deburring
Fine finishing
Cleaning
Smooth finish
Creates small chips

3. What Speed or RPM should you use your Carbide Burrs?
The pace where you utilize your carbide bur inside your rotary tool is dependent upon the fabric you have it on along with the contour being produced however it is reliable advice you do not need to exceed speeds of 35,000 RPM.

4. Do Not Apply A lot of Pressure
As with every drill bits and burrs, allow the burr perform the work and apply merely a little pressure otherwise the cutting edges in the flutes will chip away or become smooth too quickly, decreasing the life span of your burr.

5. Carbide Burrs are not as easy Than HSS Burrs
Our Carbide Burrs are machine ground from a specially chosen grade of carbide. Due to the extreme hardness with the Tungsten Carbide they can be suited for far more demanding jobs than HSS (Very fast Steel).

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

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

What are Attributes of Tungsten Carbide Burrs?
Durability
Use for too long production runs
High stock removal
Well suited for using on many hard and hard materials
Well suited for Deburring, finishing, carving, shaping and smoothing welds, moulds, dies and forgings

6. Maintain the Carbide Burr Moving around
When working with your carbide burr don’t maintain it still for days on end because this will prevent the burr from digging and jabbing into your material causing unsightly marks and roughness.

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

Stay Safe:
Always keep your burr shank is well inserted in your collet and clamped down tightly
Keep pressure light and keep the bur moving, focusing on the very best material first
Keep your jobs are secured tightly on your work bench
Don’t snag or jam your burr to your work
Wear eye protection at the least, but better yet work with a full shield for your face
