will these drill through stainless steel?

Yes they will. Stainless is always a tough job for any bit. Let the R.P.M.'s of the motor do the work and be easy on the tool pressure. Try using a good lubricant/coolant. Have fun.

Yes they will. I make spoon jewlry and for that they work. Any thicker I don't know about though.

Stainless steel in general is a soft alloy, therefore these bits should be fine according to the research I did. I have drilled soft metals but not stainless steel thus far. Just be sure to check the speed your drill should be at. If you are unsure as I initially was amazon had another set I purchased with this. It was the Dremel Diamond point set (7105 & 7144) DRE7150. It's a set of two bits which I used for hardened steel and other such materials. Last be sure you lubricate your drill bit. I use Forney 20857 cutting fluid, although you may already have a lub of choice. I hope this helps you.

I don't believe they make these units in stainless steel. Stainless steel would be an inferior material for this type of application.

Yes, using a high quality drill that is rated for stainless steel. No damage to the surface.

Probably. They are a non magnetic grade, which rules out the ferritic and martensitic grades. They work great and I have seen no evidence of galvanic corrosion between the sankey coupler and these ball lock fittings.

Yes. I used them to drill into stucco to mount brackets for my gutter downspouts. It was easy, compared to my failure with a regular drill bit.

They might, but some will not, I had two that got stuck in my Bosh hammer drill, I almost damaged the drill getting them out. If I recall these bits are $19.99 or may be $29.99. So take your chances.

Hi Scy33! No, you don't want to drill them all the way thru. Check the depth of the screw against the holding plate and the top of your desk. Put a piece of tape around your drill bit so it only drills in so far, to prevent going right thru. Hope this helps. Julie

I don't know but stainless steel is a lot harder than the metal used to form furnace ducts. I would worry it might damage the blades.

Yes these bits will drill metal. However as with any drill bit a good cutting oil is necessary to keep the drill bit cool.

Yes. The blade is stainless steel. I have been using one for the past 15 yrs. I bought this one so that I cut cut the blade at its shaft and use it in a cordless drill. Good day.

I have been using mine to drill through wood and some sheet metal (always above 20 gauge) and so far they are still going strong. I think the thickest I drilled through was 22 gauge galvanized steel but still had no difficulties. I've drilled out a few rivets and bolts as well. I suppose they will dull eventually but in my use, they have worked well especially for the money.

I don't see why not. They are made of a hard, rugged plastic with a rubber grip. To be sure you might wan't to use stainless screws, but other than that I'd say yes.

close but they are actually 1/2 inch so no 7/16......how accurate does your circle have to be? You will need a very tight drill press and vice to carry out the work. Good luck!

if i was going to try i would get a separate set of just drill bits, anything steel alloy seems to get good ratings, and i would drill a hole before running these through something that thick, one inch would be about the max, since the bits are only a few inches long and the threading teeth start about a half inch in. Just keep in mind any expensive small drill bits will still break if you don't take your time working with metal.

These do not have the holes in them. You need to look for a set labeled "Security Bits" to get the ones with holes. I would NOT recommend this set for anything other than LIGHT duty- the tips strip and the bits are NOT hardened. Best of luck and have a great day!

RM is correct. However these are clearly designed for wood or corrugated wood products. I suspect if you use these for metallic drilling they will quickly dull. Best bet is to buy bits designed for metal only.

The black plastic ones work well. I've never seen them in stainless they would be difficult to cut to fit.
