Kornor carbide burrs for metal are replaceable metal-cutting tools with a 6-8 mm shank, designed for use on straight grinding machines (SG) of electric or pneumatic type. Provide high-performance milling, thread cutting and engraving in dense and light materials.
Materials and design
- Carbide working part (tungsten carbide): ensures good wear resistance and high quality of workpieces
- Steel shanks with a diameter of 6 or 8 mm are suitable for most industrial grinders
Advantages of carbide burrs
- High wear resistance and dimensional stability (made of high-strength carbide material)
- Variety of shapes and sizes (enables efficient processing of any type of surface, including hard-to-reach places)
- High productivity (due to the hard material of the working part and high rotation speed of the drives)
- High heat resistance (extends the service life of the tool)
- Universality of application (used in processing a wide range of materials and the list of operations performed is constantly expanding)
Variety of notches
Notch shapes:
- Cylindrical (type B) with end teeth: suitable for flat surfaces and niches, effectively process different types of steel and cast iron
- Conical (type M): ideal for processing corners formed by welds, including hard-to-reach places
- Ball-cylindrical (type C): designed for radius processing and internal processing of holes
Types of notches:
- Standard (single): for high-quality processing and long chips
- Double (cross-shaped): small chips, high processing speed - suitable for fast milling and universal tasks
- For aluminum: one deep notch for soft metals, long chips
Examples of typical models:
- Cylindrical B 12×25 mm, shank 6 mm - suitable for steel, stainless steel, cast iron
- Conical M 10×20 mm, shank 6 mm - precise processing of shapes and hard-to-reach corners
- Ball-cylindrical C 16×25 mm, shank 6 mm - ideal for processing radii and internal surfaces
Types of burrs
- Type A — Cylindrical burrs (for processing flat surfaces and holes)
- Type B — Cylindrical end face burrs (for surface and sample machining)
- Type C — Ball-shaped burrs (for surface and internal radii machining)
- Type D — Ball-shaped burrs (for blind holes and contours machining)
- Type E — Oval burrs (for casting parts and fillet welds machining)
- Type F — Hyperbolic burrs with a spherical surface (for high-quality machining of casting parts and fillet welds)
- Type G — Hyperbolic burrs with a pointed surface (for chamfering and finishing of fillet welds)
- Type H — Flame retardant burrs (for casting parts machining)
- Type J — Conical burrs with an angle of 60° (for edge machining, chamfering, countersinking)
- Type K — Conical burrs with an angle of 90° (for edge processing, chamfering, countersinking
- Type L — Conical and ball nose end mills (for processing molded parts and hard to reach places)
- Type M — Conical end mills (for processing molded parts and hard to reach places)
- Type N — Reverse taper end mills (for processing corners and grooves)
