Description

Radius burrs with a concave shape and special cut. Suitable for the production and processing of outer radii and rounded edges.

Due to their special shapes, tungsten carbide burrs for flexible work on edges achieve almost precise chamfers or radii and can also be used flexibly in hard-to-reach areas. They are mainly used in steel and aluminium construction and have been specifically designed for chamfering, deburring and rounding of edges.

Cylindrical version with triple concave contour.

Advantages

The highly accurate concentricity enables impactfree working without creating chatter marks. This considerably reduces wear on the tool and tool drive.
Can be guided as desired.
Extremely flexible for use in hard-to-reach areas.
Creates almost exact chamfers and radii.

Recommendations for use

In exceptional cases, it is possible to work at less than 3,000 RPM. This is preferable for certain stationary applications or when countersinking with 360° use of the burr surface.
For applications with low stock removal (deburring, chamfering, minor work on surfaces), the rotational speed can be increased by up to 100 %.
In general, burrs are used counterrotationally or with a swinging motion. To achieve fine finishes or to achieve very smooth chamfers, pass the tool rapidly over the workpiece in the direction of rotation.
If the smallest area of the burr diameter is being used, the recommended rotational speed can be increased accordingly.

Materials that can be worked: Cast steel; Steel; Steels up to 1,200 N/mm² (< 38 HRC); Steels up to 700 N/mm² (< 220 HB); Titanium; Titanium alloys; Tool steels

Applications: Deburring; Milling; Rounding; Working on edges; Working on edges (chamfering, rounding)

Drive types: Flexible shaft drive; Robot; Stationary machines; Straight grinder; Tool machine
