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
Conical Shape. All sizes are nominal with a 6mm shank unless other wise stated.
Cut Numbers:
Cut 6 - Double Cut. Crosscut and double cut to improve control and chipbreaks. Manufactured from high grade tungsten carbide for general-purpose use.
Cut 9 - Chipbreaker Chipbreaker fast stock removal for improved control and reduced chips for use on hard materials, i.e. steel alloy 50RC, 60RC, carbon and cast iron.
Suitable for deburring and polishing of cast iron, cast steel, carbon steel, alloy steel and stainless steel etc. up to HRC65 hardness.
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.
A 19 piece metric heavy duty drill set made of 5% cobalt material with excellent heat resistance. Ideal for drilling steels with tensile strength up to 1,400 N/mm2, very hard bronze, stainless steels as well as heat and acid resistant steels. The high speed steel and cobalt construction allows for greater rigidity when cutting through harder materials.
Features and Benefits • Manufactured from high speed steel with 5% cobalt for added strength • Excellent heat and wear resistance for prolonged tool lifespan • Supplied in a robust carry case for easy portability and storage
