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°.
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.
Insert Grades QX500 (ISO P10-P25) Cerment. For high speed finishing and light cutting. Will remain a high class surface finish. Mainly used on steels and can be applied to finish some Stainless steels and Cast Irons.
Plain Shank Spiral flute, 3 flute. Medium duty. Used for milling of pre-drilled holes to allow bolt or cap head screws to lie flush with the component surface. Manufactured to manufacturers standard
