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
Series L100 HSS straight shank long series drills are excellent general purpose drills which are designed to drill steels with tensile strength up to 1,000N/mm2, cast steel, grey cast iron, malleable cast iron, nickel brass and graphite.
Features and Benefits • Manufactured from HSS for improved toughness • Black oxide coating for greater heat and wear resistance • Ideal for general purpose drilling
Typical Applications • Drilling • Steels • Grey cast iron • Malleable cast iron • Nickel brass • Graphite
Standards • Manufactured to BS 328; Part 1: 1986, DIN 340 RN, ISO 494.
Heavy duty construction manufactured from HSS and cobalt for increased hardness and durability with 6 flutes for improved cutting performance and chip control.
Features and Benefits • HHS-Co construction for improved hardness • 6 flutes for improved chip control and cutting efficiency
Cylindrical-End Cutting All sizes are nominal with a 6mm shank unless other wise stated.
Cut Numbers:
Cut 3 - Rapid Cut. for use on softer non ferrous and plastic materials, i.e aluminium, fibreglass, plastics, hard rubber and zinc alloy,
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.
