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
Insert Grade QX5030 (ISO P20-P40 M20-M30) CVD Coated. - Medium / rough turning and intermediate cutting of steel / stainless steel. Combination of toughest substrate and alumina coating (MT-TiCN + TiC + AL2O3 + TiN) having superior chipping resistance provide wide coverage.
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.
Series 36 - Regular Series Dimensions to DIN 844. Centre cutting. Threaded shank to DIN 1835D. Shank cutting diameter to +0.04 -0.0.
Uncoated (for general production machining) TiCN Coated (extends cutter life and improves work material surface finish) TiALN Coated (dissipates and resists heat, reduces surface friction coupled with high surface hardness).
