How to Sharpen a Step Bit is all about drills, drill bits and how to extend the Unibit.

For the best results, the tip and flute should be sharpened periodically.

If you don't drill until the cutting edge becomes really bad, the appropriate results can be achieved by regrinding the flute, and it is really easy to do with a coarse diamond hand lap.If you keep the drill bits sharp, they will cut nicely for a long time.

When you run too fast, the tool becomes dull and you can't use a power tool.One way to do it is using a bur.You run the burr along the cutting edge to make it square again.

It is not a close tolerance reamer.The bench grinder wheel can be used tosharpen a step drill bit.You can support the body with another hand if you hold the drill in one hand.

The drill tip should be at a 45 degree angle to the grinding wheel.Touch the edge of the wheel.Light contact is maintained while rotating drill clockwise.Follow the factory closely.The trailing edge needs to be at least 1/32” lower than the leading edge to cut cleanly.If the tip breaks, or if repeated sharpening grinds away first step, a new tip can be created.

A proper sharpening stone can be used tosharpen flutes.The cutting edge of the flute should match the factory line.

It is easy to regrind the flute if you don't use unibits until they become really bad.It is too time consuming to restore a worn out one.It is easy to keep the step drill bit cutting nicely for a long time when it just starts to drill a little worse than sharp.

It is possible to use a die grinder.To get some skills, you should practice on cheap and dull bits.The process is much easier with a special sharpening attachment.

If you are a professional and use a step drill every day, setting the angle and grinding with a fixture looks nice.It's enough for me to use a hand stone or diamond on the flute.
