Cut 9 chipbreaker carbide burrs are manufactured from a tough carbide substrate for fast stock removal, improved control and reduced chips. Ideal for use on hard materials, i.e. steel alloy 50RC, 60RC, carbon and cast iron. Features and Benefits Carbide construction for increased tool toughness Cut 9 chipbreaker geometry for fast stock removal Ideal for use on hard materials up to HRC65 Typical Applications Deburring Cast iron Cast steel Carbon steel Alloy steel Stainless steel Notes Workpiece 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 at high rpm's '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
