Ruko SPG carbide rotary burr, D 8 mm × head L 18 mm, shank Ø 6 mm

Ruko SPG carbide rotary burr for precision shaping, deburring and finishing tasks in metalworking and maintenance workshops.

• Solid carbide construction for high wear resistance
• Form G (SPG) per DIN 8033 for predictable geometry
• Cross-cut (KVZ 4) for efficient chip removal
• Shank Ø 6 mm for standard collet compatibility

Faster stock removal with controlled surface quality

The SPG-shaped carbide cutter combines a pointed-oval profile with a cross-cut (KVZ 4) tooth pattern to remove material quickly while reducing chatter. The solid carbide body delivers high rigidity, so each pass stays true to the intended contour and dimensional tolerance. For routine trimming, shaping or cavity work, this geometry shortens cycle times and produces a consistent surface that needs less secondary finishing.

Durability and repeatability that reduce tool changes

Made from cemented carbide and manufactured to DIN 8033 Form G, the tool offers a robust cutting edge and predictable wear behaviour. The combination of hardness and edge stability means fewer tool changes across repetitive tasks, which improves overall process uptime. This longevity is particularly beneficial in small-batch production and maintenance operations where uninterrupted workflow matters.

Secure clamping and straightforward machine integration

With a 6 mm shank diameter, the burr fits standard rotary tools and die grinders without adapters in most setups. The 8 mm head diameter and 18 mm head length balance cutting capacity with access to tighter geometries, making the cutter suitable for internal profiling as well as external shaping. Secure clamping and consistent run-out characteristics maintain repeatable results and reduce the risk of vibrations that compromise surface finish.

Practical handling and selection advice for workshops

The pointed-oval shape allows controlled contact on curved surfaces and edges; the cross-cut improves chip evacuation and reduces heat build-up. When choosing the right burr for the job, match the head diameter and profile to the workpiece geometry and select a suitable spindle speed for the material being processed. For safer operation, ensure correct protective equipment and observe manufacturer speed recommendations for carbide rotary cutters.

FAQ

What applications suit this type of rotary burr?
This Ruko SPG carbide rotary burr is suitable for shaping, deburring and fine profiling in workshop and maintenance environments where a pointed-oval form and cross-cut action are advantageous.

Which machines are compatible with the shank size?
The 6 mm shank of the Ruko SPG carbide rotary burr fits standard collets and rotary tools designed for 6 mm tooling, ensuring secure clamping in conventional grinders and die tools.

How does the cross-cut (KVZ 4) affect cutting performance?
The cross-cut pattern on this Ruko rotary burr improves chip fragmentation and evacuation, resulting in faster material removal and reduced heat buildup compared with straight-cut designs.

Is the cutter coated or uncoated?
The Ruko SPG carbide rotary burr is supplied in an uncoated (blank) finish, relying on the inherent properties of cemented carbide for edge retention and wear resistance.

What are the dimensional identifiers for ordering?
Order using SKU 4000602867NW; key dimensions are head Ø 8 mm, head length 18 mm, shank Ø 6 mm and overall length 60 mm.
