Introduction: Countersink From Screwdriver Bit
Ever needed a countersink when you could not find one ? Or you could not a achieve a good countersink with one you already own ? well you can take an old screwdriver bit and turn it into a countersink to use on your next project !
I used a cheap bit as its a lot easier to work with and sharpen but a good quality bit may hold a better edge.
I found it worked really well with an impact driver a drill driver, high speed low speed, it worked quite well even for large headed screws, dry for yourself to see if you can create one just like mine or even better ! If you do make one be sure to send me a photo I would love to see it !

Step 1: Cut...and..grind....
Cut the end of the bit with a hacksaw then grind a point with the belt sander, I then made the point blunt to make it easier when we add the cutting edge later.
Step 2: Filing the Cutter and Testing
I filed a flute along the ground edge there is no particular angle for this so just try, experiment and see what works best!, then sharpened it then it was ready to use !
