Sherwood Countersink Set, Countersink, Straight Shank, Set of 5, High Speed Steel, Uncoated
A quality range of single flute countersinking bits available in nine individual sizes and as a five piece set for use in the deburring and chamfering of most metals and plastics. Manufactured from high speed steel for durability and performance. Inclusive angle 90°.
Series J100 - Metric general purpose drills for steels, cast steel, grey cast iron, malleable cast iron, nickel brass, aluminium alloy and graphite.
Features and Benefits • High speed steel construction with bright finish for increased toughness • Supplied in the as-ground condition for use with non ferrous materials
Standards • Manufactured to BS 328/DIN338RN
Notes • Drills with a bright finish are supplied in the as-ground condition and such tools are used generally in the machining of non-ferrous materials.
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.
Cut 9 conical carbide burrs feature a cut-9 chipbreaker for fast stock removal, improved control and reduced chips. Ideally suited to hard materials such as steel alloy 50RC, 60RC, carbon and cast iron.
Features and Benefits • Manufactured from a tough carbide substrate for greater tool hardness • Cut-9 chipbreaker increases stock removal and chip control • Ideal for use on hard materials such as steel alloys and more
Typical Applications • Deburring • Polishing • Cast iron • Cast steel • Carbon steel • Alloy steel • Stainless steel • Materials up to HRC65 hardness
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.
Cut 6 cylindrical ball nosed rotary burrs feature crosscut and double cut profile 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, up to HRC65 hardness.
Features and Benefits • Tungsten carbide construction for improved hardness and strength • Crosscut and double cut profile to improve and control chipbreaks
Typical Applications • Deburring • Steel • Cast iron
