For 1mm thickness can it not be done with a home setup? Just asking as I haven't done this myself. I do have the cobalt tipped drill bits but never drilled metal.

Yes you very well can. Make a center punch first and drill slowly with oil lubricant, heat is the enemy. Patience is the key. It will be helpful if you have a smaller size bit to start the procedure.
Take mandatory precaution as with all tooling.

Forty years ago, I spent some time drilling holes in metal for a living: semi-skilled stuff, handle pulling, basically, but I did learn how to sharpen drills.

Stainless steel was just horrible. It is pretty hard to begin with, and work hardens under the drill.

There are people here who know real practical engineering, but here is a detail that fell out of a disused brain cell! Ideally, the point of the drill should not break through the other side before the whole tip has entered the metal. Thus, for sheet metal, the tip of the drill is ground flatter (to a larger angle). Otherwise, there is a danger of the bit catching, which can be unpleasant.

One method used for drilling sheet metal is to back it with wooden board. As suggested
. use a centre punch to make a detent in the centre
. put the sink on a flat board preferably 18 mm thick
. if your drill has variable speed, then set it to low speed
. either clamp the sink and the board or press it with your feet (one on each side.
. start the drill and gently lower it to start drilling

Be careful as the drill bit may catch the sheet metal and rorate the whole think injusring you

Alternate method is to use a tapered grinding bit. Drill a pilot hole and then use the grinding bit to enlarge the hole.

Hi,

Could someone who has used these share feedback.

Black & Decker Heat Gun (hot Air Gun) - 1800watts Kx1800

I am planing to use heat gun for DIY projector install.

Not those models. I have had a Bosch, for many years.. it is one of those tools that doesn't get very much use, but is invaluable when needed, and I think you'll find it a worthwhile addition to your toolbox.

Unless your project really requires a lot of heat, I wouldn't worry too much about the wattage. It is easy, for instance, to heat PVC enough to bend it.

Do be careful: these things are fierce. Fierce enough to cause serious burn injuries and even fire.

Have a B&D heat gun myself, not sure of the model, but it was rated for 1,750 Watts & look like the one in the pic. I'd gotten it from the UK in 2007 or thereabouts, it was bought for the purpose of warming up DynaMat sheets prior to installation.

Can't be said enough times, 1,800 Watts is a lot of power, these things are no hair-dryers, they get very hot, very quick.
Also, ensure integrity of the electrical circuit you're gonna use to power it, the amp draw of these things is relatively large & can easily blow a fuse or trip a breaker.
Stay safe & Happy DIY-ing

Good point! I missed that.

In colder countries, 1kw is the wattage of a small room heater. The classic "two-bar" electric fire in UK, (if anyone knows what I'm talking about) is 1kw per "bar."

I suspect that these things should have 16-amp (large) plugs, and be on an appropriate circuit.

Any pointers regarding shop and price would help.

I boght the crimp tool along with terminals from Goodwill Enterprices, SP Road. There are plenty of other shops too which sell these in SP road. Ebay is also a good option since going to SP road for just these is a pain.

I am not sure but I doubt the shops in JC road will sell these.

I use the B&D KTX 2500.
Mostly used to lay tarfelt sheets on a section of a roof which was cracked due to earthquake.
Be very careful - these things get super hot. And NEVER touch the metal tip part.

[Thad E Ginathom]

And NEVER touch the metal tip part.

And don't look inside it to see if the elements are glowing!

I recall a safety lesson about woodworking shops: power planers cause more serious injuries than circular saws. Why? Because a circular saw looks dangerous, whereas a power planer doesn't look anything at all, but that almost flush, invisibly fast-rotating blade can easily remove large pieces of hands, etc. Nobody messes with a circular saw, but people are often casual about power planers.

+1 to that.
But in general any equipment with open moving parts (read blades) are dangerous and should be handled accordingly.
Also - proper ear,eye and face protection is strongly advised while using power equipment.
Imagine ripping a board on your tablesaw when suddenly sawdust gets in your eyes and nose, causing you to blink and sneeze.
Best case - a crooked cut, worst case - disaster & possible dismemberment.
I regularly use circular saw, table saw, router, jigsaw, power planer, drills, drivers etc and always wear gloves/ear muffs/splash goggles/face mask.

Hi Jaguar,

Thanks for the feedback, I had bought crimp tool from SP road but did not buy terminals. I will place order on ebay since going there just for one item does not make sense.

A noob question for the Gurus here - I want to buy a basic home tool kit and came across this one on industrybuying.com.

http://www.industrybuying.com/domest....HA.DO.202809/

Is it a good buy at the price and is the website reliable w.r.t quality of goods and on time delivery?

Cheers,

If you want my advice - do not buy from industrybuying.com . They will happily accept your order, and not ship it for ages. I had to cancel 3 orders - 1 prepaid and 2 COD just because they had not been shipped for 2-3 weeks.

Try flipkart, snapdeal, amazon for good service. You may also check tolexo.com.
