Points You Need To Be Familiar With Carbide Burrs

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

1. What material can Carbide Burrs provide on?
Carbide burrs works extremely well on many materials. Metals including steel, aluminum and surefire, all sorts of wood, acrylics, fibreglass and plastics. When applied to soft metals for example gold, platinum and silver, carbide burrs are excellent as they last a very long time 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 likely be best suited to particular materials, see the next point below to discover more on the various cuts.

What Do You Use Carbide Burrs In?
Ideally carbide burrs are utilized in Air Tools i.e Die Grinders, Pneumatic rotary tools as well as speed engravers. Micro Motors, Pendant Drills, Flexible Shafts, and hobby rotary tools such as a Dremel.

Always employ a handpiece that runs true i.e without wobble.

Who Uses Carbide Burrs?
Carbide burrs are popular for metalwork, tool making, engineering, model engineering, wood carving, jewellery making, welding, chamferring, casting, deburring, grinding, cylinder head porting and sculpting. And therefore are utilized in the aerospace, automotive, dental, metal sculpting, and metal smith industries to only 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 combined with metal, hardened steel, copper, cast iron, and ferrous metals and can remove material quickly with a smooth finish. Use for heavy stock removal, milling, deburring and cleaning.

Heavy removal of material
Creates long chips

Double cut carbide burrs tend to be 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 definately 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 as a result of producing smaller chips since 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 will help 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 rate of which you use your carbide bur with your rotary tool is determined by the pad you’re using it on and also the contour being produced yet it’s safe to say you do not need to exceed speeds of 35,000 RPM.

4. Do Not Apply Too Much Pressure
Like all drill bits and burrs, allow burr carry out 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 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 could be applied to a lot 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, and for longer.

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

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

6. Keep The Carbide Burr Moving around
When utilizing your carbide burr try not to keep it still for days on end as this may prevent the burr from digging and jabbing in your material causing unsightly marks and roughness.

End on an ‘up’ stroke for the 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 the bur moving, centering on the greatest material first
Keep your work is secured tightly for your workbench
Don’t snag or jam your burr into the work
Wear eye protection as a minimum, but better yet utilize a full shield for the face
