Some Taiwan made piece, 4 to 32 (the larger in the above pic) alone is costing some 1700 INR in Pune local market.

wanted to buy one but the VFM against work is not matching .

Try the small tool shops in the bylanes between SP Road and SP Lane. Start from the mosque end. Take a printout of the pic - terminology may vary. Don't say HSS - that is the bit material; just ask for Step Drill Bit.

I'm on the lookout for a drill machine that I can use for household work and came across the SKIL drill machine set. Though this is a Bosch company I wanted to know if its better to get the Bosch drill machine instead.

Also, when a drill machine says 13mm does it mean that it can drill holes only 13mm deep or something else? Because 1.3 cm of holes don't work for TV screws so in such cases do I need to only get a new drill bit or does the drill machine also has something to do with it?

Buy bosch among the 2 . You get just the drill when you purchase .You need to buy drilling bits separately .

Bosch also has a basic drilling bit set . That should be enough for 99 % of works . It consists of 5-6 bits of varying sizes each for wood ,metal and concrete . So you will have like 15 -18 bits in the kit .

Skil isn't bad at all. Not much to differentiate. Bosch drills are originally a Swiss company (I use one I bought 30 years back). Skil is American - history going back early 20's, and used by a lot of construction professionals.

"13mm" refers to collet size, the max shaft size of bits it will accept. If the cutting dia is more than this, it will only work on softer materials, usually wood. Max. torque of the motor limits that, so take the one which has a higher max. torque rating.

The depth will depend on the material. Any drill will go a lot further into wood than concrete, and further into concrete than steel.

I think that the specification you are looking at rates the maximum diameter of drill bit that the drill can use. Or, at least, the max diameter that will fit into the chuck: some drill bits may be larger at the business end than the chuck end. Flat bits for wood have quite small shanks, but the business end may be much larger than 13mm.

Swiss, American? You might be right, if you'd ask me i would have said German and Swedish. Over the year I have owned any number of power tools. Skil is good, but over the years I have developed a personal preference for Bosch. i find them more robust, they last longer and are better designed in how you hold them and use them etc. Its purely personal preference I guess.

Nothing scientific to it. Oh and I like the Bosch green better than the Skil grey.

Normally when the drill says 13mm it means that it has enough power to drill 13mm diameter holes in steel, hence it comes with a chuck which will accept 13mm diameter shaft at the most. This is true for medium & heavy work in factories and construction sites. For normal house hold work, especially wood and masonry you can drill larger diameter holes, albeit at a slower rate. That is why most of the drill bits for household work come with shanks that are 10mm, but bits may be larger - 13mm to 25mm

Earlier I had bought Bosch DIY kit which contained Bosch Drill machine. Current DIY kits contain machine from SKIL. I think power of the drill machine is reduced (compared to earlier). If it has more power, it also will have hammer drill for Hard surface.

As far as Drill bit is concerned, you will get 1 bit for each purpose (1 for wood and 1 for concrete). the 13mm, I believe is for concrete. You need to put chakke (the wood piece) and tighten screw for holding in concrete. It won't be a problem. However you can buy drill bit set separately which can be used with your machine.

If you want your drill machine also to be used for tightening/loosening the screws, you need to check if drill machine does that.

Thanks for the responses, now to elaborate on the drill requirement. I would need it like 3-4 times a year (may be even less), to drill holes for toiletries stand, something around the wash basin, hang some heavy frame pictures, may be even the TV next year, you know the regular household stuff.

The thing is that I've recently shifted base and I would like to drill holes as I go along setting up stuff around the house. I don't want to rely on the friendly neighbourhood electrician who wouldn't always use the water-level meter and hangs stuff at 10-15 degree angles. Not to mention ruins my Sundays because he's usually 2-3 hours late.

So I reckon that 10mm is good enough for someone like me, I'd rather buy the 13mm one if I'd need it in another 7-10 years as I'm assuming the Bosch/SKIL drill machine should last at least this longer. However, I couldn't find 13mm Bosch drill machine in the regular online shopping dotcoms.

My budget would be not to go beyond 3k for now (drill bits included) simply because I'm getting SKIL at this price, the complete set. If I can get a similar set for Bosch I'm willing to extend it to 4-4.5k (assuming I wouldn't need something like this for another 10 years).

Now I went to the Bosch India website and looks like I have to choose between GSB 10 RE Professional and GSB 13 RE Professional.

The only confusion, is 10 RE going to be good enough for someone who doesn't even qualify as a DIY'er?

EDIT: I almost forgot to search ebay for the price. Looks like GSB 10 RE (complete set) is available between 3.5k to 3.8k and GSB 13 RE (complete set) is available 5k onwards.

If you are going in for long term, then I would suggest you to buy a heavy duty 13mm hammer drill. You may be spending a couple of thousand of Rupees more, but getting a much superior product.

Some of the advantages of this drill is
. 600w motor, so drilling is faster
. Ball bearings, hence will last longer
. Overload clutch, no burn outs
. Variable speed

I bough my 13mm drill - "Wolf" brand 40 years ago and it is still going strong. Lower power drills have lighter motor, and most important light bearings. Nothing beats ball/roller bearings for extended long life.

EDIT : Good quality tools last a lifetime, where as inexpensive ones result in skinned knuckles and burnt out motors.

Gosh, does it? It is nearly forty years since I used to drill holes for a living (unskilled/semi-skilled factory jobs back in my hippy days) but I don't think I would want to even try drilling a half-inch hole in steel with a hand-held machine

There are specialist drill bits for almost every material one can make a hole in --- and that includes tiles. Whilst one can use a "masonry" (for brick and concrete) bit, a made for purpose tile drill is much better. Why? ceramic tiles are quite fragile, and a cracked or shattered one will do nothing for the appearance of your bathroom!

Get plenty of practice on untiled walls before you try tiles. And then you need to find out how not to have the bit skid across the surface.

Exactly. Buy a drill for life, especially if your usage will be light. That doesn't mean you have to buy something huge, which will be heavy and hard to use in the unpractised hand. You can make that upgrade when you decide to go in for building full time!

All wise advices as usual from Thad and Aroy.
I have both Bosch and a Makteck - Japanese drills. The latter has adjustable speed controller built into its switch so that you can start with a slow speed and then increase once the pilot hole is bored. You can also drive screws in/out using the slow speed setting.
The adjustable speed comes in handy for drilling in tiles as it avoids skidding.
