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 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.
Insert Grade QX8010 (ISO M10 S10) Coated. Excellent grade giving superior results on heat resistant super alloys, especially for the aerospace industry. TiAln based coating ensures high wear resistance on these demanding materials.
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
