I am making a base for a motor and would like to add slotted holes to the angle frame to slot cutting drill bit for metal 3d me to adjust the belt tension. Unfortunatey, I do not have a milling machine, but I do have Like I say, I do not know that i have the skill to use the torch for this Any thoughts?

The drill press and jig saw idea should work out okay. You could also drill a series of holes and file out the remaining stock.

It would take slot cutting drill bit for metal 3d while, but it would work. The torch could make a big mess, but could work quite well.

I'd practice in some scrap material to see if you can get an acceptable slot. Maybe set up some guides to help keep things under control. Keep on trying and you'll figure it out one way or another. The material is cheap so you can always start over if you have to.

Works best to drill your holes spaced so that a small web is left between holes. Use a good center punch to mark locations and take care when drilling so that the drill doesn't wander into a previous hole see note below about rail The saber saw will work fine; but use lower speeds. Another thought is to buy an end-cutting end mill that you could use to step-drill out the web. Rigidity is a must, however.

Hand file to clean up. Rat-tail files work good for this. Thanks for the suggsestions slot cutting drill bit for metal 3d I appreciate it. Originally Posted by gatz. Mike C.

Endmill in a light duty drill press is a recipe slot cutting drill bit for metal 3d disaster, even just trying to plunge cut. The flutes want to walk around the hole and there is not enough radial rigidity to keep it from going wild.

Just drill the holes close together as you dare and get with it. While I agree with Mike about the shortcomings of using an endmill in a drill press; it can be done. I've done it using a short 4-flute end mill. Do not try to "mill" with it by moving the part. That definately is not the thing to do, and will end up in disaster. As in previous reply, the idea is to use a fence or something mounted on the drill table that the part can be clamped to, then carefully plunge out the web.

Don''t have to do it all at once Choke things up; that is, make sure the endmill and part are as close as possible before plunging.

Your own idea is a better one than the other suggestions you've gotten.

Drill at the ends and saw out the rest. Much less work than creating a bunch of peaks from multiple holes slot cutting drill bit for metal 3d then filing them out. Once you drill your end holes you'll likely have to file one of them square a bit to allow your saw blade to start where it needs to, and then a minimal amount of filing to smooth up the sides once the sawing is done.

I agree with Mike that an endmill has no place in a drill press. Drill presses are made to run self centering tools, and self centering is not a characteristic of endmills. Yeah, after reading all the advice, I think the multiple holes with the drill press thing sounds the most practicle for me. Although, it would be a good excuse to expand the collection Thanks again. A good file will make for very quick and clean work. A hack-saw blade wrapped in tape can also be used to open up the gaps if they're too small to get a file in.

Doing it this way also means that you'll get some one-on-one time with a file, and improve your skills. So here's the update.
