open the hole into what material?

if wood just buy a forstner bit or 45mm hole bit.

I have this. Brought from Amazon. Very usefull to open multi type of hole. A must keep tool in toolbox.

Can open hole for any material included sheet metal.

For local, try CT hardware and ACE.

For bigger size hole, the shank only support 16mm chuck and above.

This is my 3set. The bigger size cannot go into smaller drill.

My Makita cordless can fit. But another Bosch cordless cannot fit.

The biggest size is 10mm shank. (For the Ø32mm pic)

But if you looking for Ø45mm, not sure what is the size of the shank.

Go to CT hardware Bandar puteri and check la.

I do see some hardware shop got sell. Can't recall where. Those selling powertools have high chance stock.

Acrylic /= Polycarbonate

Polycarbonate is often found as flat, sheet material. The window of the laser cutter is made of Polycarbonate because polycarbonate strongly absorbs infrared radiation! This is the frequency of light the laser cutter uses to cut materials, so it is very ineffective at cutting polycarbonate. Polycarbonate is a poor choice for laser cutting.

Sos

Oh, you remind me that I have a set of laser too. Hehehe...

Don’t no chunk in where also.

Thought can set the power level ? Set it lower power and few pass. But the burn mark remain, not sure la.

Does the machine have a material preset?

Disco light kua ?

I also don’t no what use with it. Haven’t really try it.

I think the watt doesn’t that high.

Probably you don’t need to buy that hole cutter. Use a bigger drill bit you have. Than use a pen knife slowly cut the hole. That plastic not that tough. The switch should cover the ugly hole nicely.

This jap wood making is like a craft already.

Let me share some jap typical workshop.

Last month visit my sifu who love wood making. He convert the car garage into workshop. Everytime visit him, he will proudly showing me all his wood making product.

He is slowing down with age. Want to give me all his tools.    I m prepare a container to ship over here. 

Not kidding you. If you can afford to buy a house here, you can get 2 house with big land over there. Kampung area la.     The view is this..

Aiya, no need so susah drill la.

Teach you the easy way.

Go get a kitchen faucet that have a hot and cold selection. Below the faucet have 2 flex hose input. 1 cold input connect to usual household piping. And the hot water input connect to the water filter side.  Done.

Save your money and energy and your sink.

Don't forget my teh tarik.

A ler, kid question also want to test me. 

I demand Starbucks latte, tall wan, than I give answer. 

What is that shank diameter? Better train to use. Large diameter hole cut require more steady and strong arm.

Hold grip the cover firmly.

good luck hand drill thick SS, lube mahu ada to cool bit head down

tell us later how many minutes you drill

12mm can't use on my Makita 12v. 

Only can use on my bosch GSB16RE and higher.

Thanks for the reply.
I think buying a mixer tap will probably going to cost me RM100, 200+? Plus the direct water pipe water can be un-filtered. And there will be slight contamination.
Still a good suggestion tho. I will see if i will adopt this if the drill or making hole at the sink is really a no no for me.

Wah, you not ocd right ?

Don't see the syabas water that bad la. It is drinkable also. You can let the water flow out few sec 1st before get the water. And you do have an outdoor water filter.

The mixer cost Probably RM250 or over. Still cheaper than to buy a drill + drill bit + hole cutter + time + sink (if damage)   Seems no experience of drilling ?

The sink SS is not more than 1mm thick. Don't even think you can get a 2mm thick sink either. It is not difficult to drill. But require experience. To cut a big hole on SS material, drill a pilot hole 1st. Always lubricate the drill bit by water during drill if don't have cutting oil. This to avoid the drill bit damage and the sink SS turn into rainbow color. After drill the pilot hole than use a hole cutter. Do not straight away jump to use a big drill bit.

If really obsess about contaminate water (that sound really bad about Syabas water)    ,  You can use this Faucet. That is also answer for idoblu question for 3 input. No need susah drilling.



It is cold, hot and filter water faucet. idoblu Starbuck latte please.
