Carbide burrs

Tungsten carbide burr (rotor cutter) DIN 8032/8033

Applications recommendations: • Enables high turning speeds. Please note our

• For poor heat conductors such as stain- less steel, titanium alloys etc. we recom- mend a significant reduction in turning speed to avoid damaging the tool. Blue staining to the shank and tool should be avoided. • For low stock removal (deburring, chamfering, light surface treatment), the speed can be significantly increased. • For heavily lubricating materials it is sensible to use lubricants (grease, petroleum, chalk or other) to prevent the tooth system clogging. Carbide burrs can, in principle, be reground. Regrinding of small and miniature burrs is not advisable for reasons of cost.

turning/cutting speed recommendations. With stationary or countersunk jobs with 360°-wrap this burr can be exceptionally used at speeds below 3000 min -1 . • Only use with rigid clamping systems/drives; tool beat and rattle leads to premature wear. • The contact surface of the burr to the workpiece should not exceed one third of the circumference during processing. An excessively large wrap angle of > 1/3 leads to restless milling behaviour. This leads to tooth breakage.
