Rotary burrs

Tungsten carbide rotary burrs for metalworking, mould repair and surface finishing. This group includes flat cylindrical ends, radius cylindrical ends, conical ends and tree-shaped ends. Diameters range from Ø2mm to Ø25mm, with cutting lengths of 10-32mm. Shanks are available in Ø3mm or Ø6mm.

Rotary burrs use diamond cut or single cut depending on the material. The range dedicated to aluminium has a specific tooth design that prevents chip clogging. Rotary burrs mount on handheld pneumatic grinders or vertical spindle grinders and work dry, with no coolant required.

Titania supplies genuine FERVI carbide rotary burrs imported from Italy, with full warranty according to the manufacturer's terms. This type suits both small machine shops and large production lines.

Carbide rotary burrs serve metalworking applications across many industries, from mechanical manufacturing to mould repair. This group includes burrs made from hard tungsten carbide alloy. They withstand heat and abrasion at a high level, making them suitable for contact with steel, cast iron, stainless steel or aluminium.

The burrs in this group come in a variety of shapes to meet different machining requirements.

• Flat cylindrical ends, radius cylindrical ends.
• Conical ends, tree-shaped ends.
• Used for grinding flat surfaces and creating grooves.
• Used for chamfering edges, cleaning welds or enlarging holes.

Cutting head diameters range from Ø2mm to Ø25mm. Cutting lengths run from 10mm to 32mm. Common shanks are Ø3mm and Ø6mm. They mount on handheld pneumatic grinders or vertical spindle grinders.

Some ranges use diamond cut or single cut. The choice depends on the material being machined. The range dedicated to aluminium has a specific tooth design. This design helps prevent chip clogging. This group requires no coolant. They perform dry grinding. Suitable for both small machine shops and large production lines.

Classification by cutting head shape

The shape of the cutting head determines access to the work surface and the type of groove that can be produced. Flat-end cylindrical burrs such as AxSC and BXSC serve flat surface grinding and square corner work, while radius cylindrical ends such as CxSC and CxDC help create curved grooves or soft chamfers. Radius conical ends appear in the codes F10AL6 and F12AL6, allowing holes to be enlarged or precise angled surfaces to be formed.

Tree-shaped ends such as HxDC, FxDC and ExDC can reach narrow positions, cut deep grooves or clean complex welds. The truncated cone range such as L03DC3, L06DC6, L08DC6, L10DC6 and L12DC6 suits hard metal machining thanks to the diamond coating. Each shape addresses a separate group of tasks, helping users select the right tool for each machined part.

Classification by workpiece material

The material being machined directly influences the tooth design and the alloy composition. The range dedicated to aluminium and non-ferrous metals includes A12AL6, BxAL, EXAL, CXAL, H08AL6, H10AL6, H12AL6, F10AL6, F12AL6 and L10AL6. These burrs have teeth designed to prevent chip clogging when machining aluminium, non-ferrous alloys, plastics or plexiglass.

The range for steel, cast iron and stainless steel uses diamond cut or single cut, and includes BxDC, AxDC, BxDCxL, HxDC, FxDC, ExDC, H08SC6, H10SC6, H12SC6, G03SC3, G06SC6 and G12SC6. Diamond cut extends service life when machining hard materials, while single cut produces a smoother finished surface.

Sizes and shank length

The cutting head diameter and cutting length determine the application range. Small-diameter burrs from Ø2mm to Ø6mm such as L03DC3, G03SC3 and G06SC6 suit small parts, narrow grooves or positions that are hard to reach. Medium diameters from Ø8mm to Ø12mm appear in H08AL6, H10AL6, H12AL6, L08DC6, L10DC6 and L12DC6, covering most common machining tasks.

Standard shank lengths usually run from 38mm to 77mm, while the long-shank range such as BxSCXL and BxDCxL has a greater overall length for reaching deep positions or mould cavities. Common shanks of Ø3mm and Ø6mm are compatible with the collet chucks of handheld pneumatic grinders or vertical spindle grinders. Users should check the shank diameter against the machine collet before making a selection.

Cut types and applications

The cut type affects the material removal rate and the surface roughness. Diamond Cut appears in BxDC, AxDC, BxDCxL, HxDC, FxDC, ExDC and the L range (L03DC3, L06DC6, L08DC6, L10DC6, L12DC6), extending service life when machining hard steel, stainless steel or cast iron. Single Cut types such as H08SC6, H10SC6, H12SC6, G03SC3, G06SC6 and G12SC6 produce a smooth finished surface, suitable when low roughness is required.

The aluminium-specific range such as A12AL6, BxAL, EXAL, CXAL, H08AL6, H10AL6, H12AL6, F10AL6, F12AL6 and L10AL6 has a specific tooth design to prevent chip clogging and reduce the heat generated when machining aluminium, non-ferrous alloys, plastics or plexiglass. Users should choose the cut type according to the material and the required final surface.

Multi-purpose rotary burr sets

A rotary burr set contains several pieces covering many tasks without buying each code separately. F008-6 includes 8 pieces with a Ø6mm shank, while F008-3 also contains 8 burrs but with a Ø3mm shank. These sets usually contain tree-shaped and ball-shaped burrs. They also include flat-end cylinders, round ends and conical ends. Suitable for small machine shops or repair technicians. They meet the need for flexible tooling. Users should check the list of pieces in the set. This helps ensure all required shapes are present for regular work.

Operating notes

Carbide rotary burrs run at high speed, usually from 6,000 to 35,000 rpm depending on diameter and workpiece material. Speeds that are too low reduce cutting performance, while speeds that are too high cause local overheating and shorten service life. Users should refer to the speed recommendations from the machine manufacturer or the technical documentation for the burr. Excessive feed pressure causes the burr to wear quickly or break, particularly with diameters below Ø6mm. Let the burr cut by itself and simply keep the direction of travel steady.

Carbide rotary burrs work dry. No coolant is needed. However, good ventilation is required to dissipate heat and remove chips. When machining aluminium or plastic, chips easily clog the cutting flutes. Stop periodically to clean them. A stiff brush or compressed air can be used. Wear safety glasses and a mask to prevent chips entering the eyes or metal dust being inhaled. After use, store the burrs in a separate case or on a rack to prevent impacts that could chip the cutting edges.

The carbide rotary burr product group offers a range of machining options for steel, cast iron, stainless steel, aluminium and non-ferrous metals. Choose the correct cutting head shape and cut type. The size must match the material being machined. Doing so increases productivity and extends tool life. Users should review the technical specifications of each code. This helps ensure compatibility with the machine and meets the requirements of the machined part.
