Malco hole cutter
Can the bit on the Malco hole cutter be sharpened? I know how to sharpen a drill bit but this bit cuts on the side not sure how or even if can be sharpened.

I'm tired of these mediocre "semi flammable" refrigerants. If we're going to do it let's do it right.
Unless we change direction we are likely to end up where we are going.

I'm pretty sure you can't sharpen the side of a drill bit now if it was an actual milling bit that would be a different story.

I always drill the initial hole with a zip screw when drilling into sheet metal. The tip of the drill bit lasts much longer.

x2. Zip screws are useful in many ways.
To answer your question you can sharpen it if your careful and get the angle just right. But as other's have said it's usually not worth the time.

Now if you are meticulous enough to save up a bunch of them like say maybe 10 of them you could probably take them to Fastenal and send them in to be sharpened. But the problem is if it's the side that's dull and they aren't cutting the circle very well then it's not going to do anything because they only sharpen the tips for drilling.

Point taken. Already replaced.

The problem is the tip isn’t the real issue. It cuts on the side and that’s what you can’t sharpen. Honestly a new bit is something your company should buy you.

I don’t see why they couldn’t be sharpened being they have to be sharpened to work in the first place. Like already mentioned, prolly not worth it but would be neat to know how they do it.

Well they are carbide for one thing. I do have a drill bit sharpener that I believe would sharpen the tip. But my guess is the side cutting edge is being done by machines in a factory that are worth more than the homes we live in so yeah it’s kinda outside diy range
