Star-M 601 range of Drill Bits are precision milled and cuts cleaner than any drill bit you'll ever encounter. This is achieved by having the pin perfectly in the center of the drill, which will always create a centred hole. These super clean cut drill bits are extremely efficient in both cross cut as well as with the grain.
Designed specifically for soft materials like wood, hard wood, rubber, acrylic board and PVC that can otherwise be problematic to drill, the knife-like flutes of the Star-M bits deliver precise cuts in even more fibrous materials, such as bamboo.
Hooked spurs clear any remaining waste from the perimeter of the cut, these are followed by semi-circular wings that incise a little deeper to part the waste from the surrounding material. A curved cutting edge then planes the waste out and sends it up the flutes.
For plastics use a low speed setting, for fibrous materials use your highest speed setting, and in both cases introduce the bit to the material gradually.Specifications:

Super Clean Cut Drill Bits
These are by far the best and sharpest drill bits I have ever used, a clean cut every time!
I've used these drill bits for sometime in making musical instruments. I know no finer drill bit
These are beautiful bits to use. I am currently working a project requiring clean and very accurate holes. These bits really do the job. The brad point is easy to position accurately and tracks precisely. The very sharp cutting surface make a very clean hole with very little breakout. The bits are a bit shorter than you might expect, but this has not yet been a problem in my project.
Best cutting drill ever. Never before seen holes as clean.
