Carbide Burrs

Why Carbide Burrs

Tungsten Carbide Burrs are used for cutting, grinding, deburring, removal of sharp edges, and shaping the workpiece. Carbide burrs are used on a variety of materials including aluminum, metals, steel, cast iron, fiberglass, wood, acrylics, and plastics. Carbide burrs are ideal on soft metals such as silver, gold and platinum because they resist chipping or breaking and have a long tool life. Allow the tool do the work when using burrs, apply minimum pressure. Applying too much pressure can result in shortening the life of your burr, in addition to potential chipping/eroding of the flutes.

Carbide burrs are widely used for metalworking, chamfering, casting, deburring, and grinding. They’re also used in a variety of industries including welding, tool making, engineering, woodworking, jewelry making, aerospace, automotive, dental, metal sculpting, and many more! Carbide burrs are typically used in die grinders, rotary tools, high speed engravers, dremels, pendant drills, and flexible shaft grinders.

What material can Carbide Burrs be used on?

Carbide burrs can be used on many materials. Metals including steel, aluminum and cast iron, all types of wood, acrylics, fibreglass and plastics. When used on soft metals such as gold, platinum and silver, carbide burrs are ideal as they will last a long time with no chipping or breaking.

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

Different cuts of carbide burrs will be best suited to certain materials, see the next point below to find out about the different cuts.

Tungsten carbide vs HSS

Generally a metal burr is made from either Tungsten Carbide or High Strength Steel (HSS). Tungsten carbide burrs are preferred when working with metal. Due to their extreme hardness they can be used on much more demanding jobs and won't wear out, unlike HSS. What's more, HSS has less tolerance for heat and will start to soften under high temperatures. Tungsten carbide burrs set will last longer and perform better under higher temperatures.

Why we recommend Tungsten carbide burrs?

• High stock removal
• Great for deburring, shaping, smoothing welds, enlarging holes, carving and finishing
• Last longer
• Perform at high temperatures
• Ideal for all metals

Where tungsten carbide burrs can be used on any metal, there are different cuts available to suit different metals, see below.

Types of cut

Metal burrs come in either a single/aluminium (Alumin Range Burrs) cut, or a double/diamond cut. Large single/aluminium cut carbide metal burrs have a single right cut spiral flute and are used with cast iron, steel, copper, brass, and other ferrous materials such as aluminium. Single cut burrs will provide faster stock removal with no clogging (clogging is common with aluminium), however they will not provide as smooth finish as double cut carbide burrs. Double/diamond cut have both a right and left hand cut providing a faster and finer finish. These are commonly used on steel, stainless steel and other hard metals.

Double Cut

Used on ferrous and non ferrous metals, aluminium, soft steel and also for all non-metal materials such as stone, plastics, hard wood and ceramic. Double cut have more cutting edges and will remove material much faster. Double cut will leave a smoother finish than single cut due to producing smaller chips as they cut away the material. Use for medium-light stock removal, deburring, finishing and cleaning.

Designed for medium- light removal of material, deburring, fine finishing, cleaning, smooth finish, and creating small chips.

Single Cut

Usually used with stainless steel, hardened steel, copper, cast iron, and ferrous metals and will remove material quickly with a smooth finish. Use for heavy stock removal, milling, deburring and cleaning.

Designed for heavy removal of material, milling, deburring, cleaning, and creating long chips.

Aluminum Cut

Non-ferrous are exactly what you would expect them to be. Use our cutting tools on non-ferrous materials such as aluminum, copper and magnesium.

Stay Safe:

• Always ensure your burr shank is well inserted into your collet and clamped down tightly
• Keep pressure light and keep the bur moving, focusing on the highest material first
• Ensure your work is secured tightly to your work bench
• Don't snag or jam your burr into your work
• Wear eye protection as a minimum, but better still use a full shield for your face
