Drill bit for Sanding Computer Case (ie sheet steel)?

post #1 of 8
Thread Starter 
I'm having a lot of difficulty on this subject. A drill bit is way cheaper than buying a hand file, and I have a million drill bits so I probably already have the right drill bit for the job (don't tell me to just buy a hand file, I have like 50 of them at the family house, but I'd rather not spend half a day getting a hand tool when I likely have the $2 drill bit here at home).

I have a Conical Rotary File, I thought this was the right bit, but I can't tell what direction to spin it (it appears the left way, which is the counterintuitive way for drill bits, is 'better', but I have no clue what speed to be using these or what force to apply so I'm probably using it wrong in both directions). I can't find any info on how to use this bit, I just end up with a bunch of dentist stuff on it.



Maybe another bit is better? This is for sanding rough edges in the computer case from holes I've drilled (drilled holes for screws, hole saw holes to install 140mm fans where no hole existed before, etc).

I'm really cutting this case up (bitfenix shinobi, it's steel), so I need a way to debur and sand the rough edges. Doesn't even need to be anywhere near perfect, really. I also have a ton of sand paper and drywall sanding paper, 50 grit to 2000 grit, I could just use that...

tldr how to use a conical rotary file, what speed and what direction, for sanding steel on a computer case.

To debur smaller holes use a few sizes larger bit to slightly countersink the hole. For larger holes just use sand paper by hand. That bit seems a little rough, I would just use sand paper for any rough straight edges you have, if your not going to use a file which would be the correct tool. You can use sand paper over a straight edge also like a sanding block.

I didn't realize I could use sanding paper for sheet steel. What grit would I use? There's also some large burrs, what do I do about those? I can't just sand those off.

I don't know if you mean like a conical rotary file bit that's a bit larger, or like a drill bit, but I can't just make the hole bigger seeing as it's for a specific size of screw.

I can't imagine that there just doesn't exist a power tool/bit for this task. There's always a power tool or bit for everything.

You dont drill completely through your smaller hole with the larger bit you create a very small counter sink to deburr like in this PICTURE. The countersink you would be making would be much shallower in this, just the tiniest amount to deburr the hole. It wouldnt even really be called a countersink just the smallest touch from the larger bit to clean up the hole.

If your starting with large burrs they need knocked off with a file then the edge can be cleaned up with emery cloth or probably around a 600 grit sandpaper, just experiment with different roughness. It doesnt take much to round a sharp edge on thin steel with paper or emery.

What is the point of the conical rotary file then? Why does it exist? What purpose does it serve?

I'll practice with drilling countersinks on the metal flaps you pull off to open the cd bay slots. I have tons of sandpaper. I'm still confused on what to do, I understand a file is perfect but given that I don't have my 50+ files here, and that I have tons and tons of drill bits and sand papers (not to mention drill bits are like $1-2, a fraction of the gas or time cost of me going to retrieve a file), what do I do.

The job really doesn't need to be perfect. All that's holding back about 20-30 pieces of a custom built, fully sleeved Z87 computer (like I have EVERYTHING), is a few rough edges that are going to be squashed and covered up anyways. I literally don't need to sand this stuff at all, I could just be done with it. So, is a conical rotary file just not as good as a hand file, or is it just like the totally wrong tool, like trying to use a drill bit instead of a screw driver bit.

yea... i mean i appreciate your input but I'm not so sure I can use it. Sandpaper isn't going to work with the rough burrs and edges on some of it.

I used a 140mm hole saw on the front of the steel frame (where there are/were 2x120mm holes). So I didn't just cut through plain steel sheet, I also cut through fan grilling and screws holes and all sorts of notches. So sandpaper might work on some of it, but not all of it.

As for the screw holes, well, if I screw up with the counter-sinking, I'm REALLY screwed because I can't exactly just move the screw holes elsewhere. I can practice on some steel sheet, like the tabs you pull off a case to expose the CD bay slots... but I don't know how comfortable I am with this idea.

I get that a hand file would work well here. Great. But that's not an option. So what drill bit would do this job, as I most likely have the right drill bit here right now.

For deburring the holes using a larger bit, I'd recommend going double or more of the size. You don't even need to use the drill for this, but you really only need to lightly press the bit against the hole and turn it about 1 full turn. You can do this with the bit in your hand. You're not looking to remove material from the steel, just shear loose anything that's sticking up.

For deburring the rest of it, I'd recommend making a narrow sanding stick or block, around 1" or so on one side, 1/4"-1" on the other, and about 6" long. Wrap a sheet of 100 or 200 grit paper (preferably the red oxide coated ones) around the block and staple in place (or just hold it with your hand if no staples around). Where you've cut and there are sharp bits sticking up, take a shot at them with the sanding block at about a 45 degree angle, moving downward into your opening. Once any major stuff is cleaned up, run the block side to side along the cut line, and rotate it a little into and out of the cut to round out the edge slightly. Occasionally feel with your fingers (just touch lightly, never slide fingers along the cut edge on sheet metal) to see if it's got any rough parts.

Really, deburring of sheet metal parts may not matter in the overall looks of your case, however it's good practice. I'd hate to find a really sharp edge later on while trying to run wiring, either with the sleeved wiring or a finger. Sheet metal can be some bad stuff.
