Stainless Steel Sheet Metal
If you warmth up the stainless steel, it's going to flip very exhausting and you will have a very tough time drilling thought it. Now I can admire this tools beauty and craftsmanship because it sits in my device chest for the next 20 years until I resolve to clean out my garage. I bought this to drill a gap in my stainless steel sink for a soap dispenser. I used a punch to make a small dent in my sink so the drill bit would not stroll. I built a hoop with plumbers putty just larger than the bit.
In the picture you see of my bumper, I had 2 different saws that have been just warping and slicing all over the place. This product made fast work of what these others saws struggled to do. If you see any signal of smoke whereas using this, cease, add more oil and decelerate your drill.
Those who work with it regularly are prone to have a sheet steel bending brake of their workshop, however this device could be a bit expensive for the hobbyist. Thankfully, there are a couple of pockets-friendly choices that may assist you to get the job carried out. I've reduce over 5 dozen holes in 1.5mm steel cover plates for Neutrik XLR panel mount connectors.
Check the manual that comes with it and be sure to set the velocity appropriately. Don't drive it - it is not exceptionally quick at cutting, however when you let it reduce at an inexpensive speed it will work fantastic. I would estimate the bumper I reduce is between 1 to 2mm thick and a few level of steel more durable than stainless.
put the ring around the dent I made, crammed the ring with some software oil. This allowed me to drill in an oil bathtub, maintaining the drill bit nicely lubricated and cool. I put my cordless drill on the low gear setting so I would spin slowly after about 30 seconds to a minute, I had the cleanest, smoothest, most perfect gap I might think about.
This gap saw by far exceeded my expectations and did not look any worse for wear by the tip of the minimize! I did use slightly oil to assist nonetheless, which isn't a bad thought when working with tungsten. This hole noticed is by far the heaviest I have and sturdiest out of my collection of varied gap saws from different manufacturers and sizes from 1' to 3'.
I also had a multitude under my sink where all of the oil and shavings fell beneath so you may need to put an old rag under the sink to catch the mess. Drill bits are available in a variety of sizes and shapes, and can be found in quite a lot of supplies and coatings.
