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
Crosscut and double cut 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 etc. up to HRC65 hardness.
Features and Benefits • Hard carbide construction for increased cutting hardness • Crosscut and double for improved chip control and chipbreaks • Suitable for deburring and polishing of materials up to HRC65 hardness
Typical Applications • Deburring • Polishing
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
Senator jobber drills are roll forged from HSS, ensuring uninterrupted grain structure. This provides exceptional strength and durability. Tips are ground for effective cutting. Suitable for drilling wood, plastic, carbon and plain steels where the cutting efficiency of ground flute is not required.
Features and Benefits • HSS construction for increased rigidity • Ground tips for effective cutting performance • Ideal for use on a range of substrates including wood, plastic, carbon and steels
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
