Cut 6 double cut tungsten carbide rotary burrs feature a crosscut and double cut to improve control of chipbreaks. They are manufactured from high grade tungsten carbide for general-purpose use. Features and Benefits Tungsten carbide construction for increased strength Crosscut and double cut improves control of chipbreaks Ideal for general purpose machining Typical Applications Deburring Polishing Cast iron Cast steel Carbon steel Alloy steel Stainless steel up to HRC65 hardness. Notes Work piece and tools should always be steady and well supported. Carbide burrs are not suitable for 'milling' large amounts of material, they are for light stock removal and high revolutions 'LOW FEED - HIGH SPEED'. Always ensure that at least 70% of the shank length is clamped by the collet or chuck of the tool being used. Always ensure that the tool is rated to the recommended operating speed of the burr.
