Machine Flat Bit
Quality classification: Hobby
The description of the tool design: Classical centre bit with brad point. Polished face with two roughing taps and bit shank. The extension shank 3511.305 has a chuck which permits fast exchange
Tool material: Tool steel
Recommended r.p.m. and specific example for the most common diameters in the according field of application: 800 - 3000 min-1. e.g. Ø 18 mm 1600 min-1 in softwood. Also find details at the speed-diagrams
Description of application: For boring into softwood without precision and quality. Because of the roughing taps results are clearly better than with the usual versions
Practical advice and specialty of the tool: In our opinion flat centre bits are in principle no tools for professional use and are not fit for hardwood. It is better to use FAMAG cylinder boring bits, especially Bormax®
