Sherwood Countersink Set, Countersink, Straight Shank, Set of 5, Cobalt High Speed Steel, Uncoated
General purpose chamfering/deburring and countersinking tool manufactured from durable high speed steel with a bright finish. Featuring 3 ground flutes for optimal performance.
Features and Benefits • Manufactured from high speed steel for improved rigidity and stability • 3 flutes for efficient chagrining and deburring performance
HSS multi diameter step drills produce good quality holes in a wide variety of sheet metal, using either a bench drill or light pedestal drilling machine. Manufactured from high speed steel, they offer sound rigidity, strength and stability when machining. Each tool cuts parallel holes in a range of specific sizes and is compatible with materials up to 1/8" (3mm) thick.
Features and Benefits • High speed steel construction for greater strength, rigidity and stability • Excellent wear and heat resistance for prolonged tool life • Cuts parallel holes in sheet metal
Crosscut and double cut to improve control and chipbreaks. Manufactured from high grade tungsten carbide for general-purpose use. Suitable for deburring and polishing of cast iron, cast steel, carbon steel, alloy steel and stainless steel etc. up to HRC65 hardness.
Features and Benefits • Hard carbide construction for increased cutting hardness • Crosscut and double for improved chip control and chipbreaks • Suitable for deburring and polishing of materials up to HRC65 hardness
Typical Applications • Deburring • Polishing
Please note: • 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
