If you are 'serious' about drilling holes then you must consider restoring the cutting edges of your bits.
It is not Rocket Surgery but there are some defo rules you need to be aware of.
A short cut to this is to use a Drill Doctor.
It will restore you bits to a factory finish in a few seconds.

And learn a out 'Speed and Feed'. The most important t issues with regards to drilling.

If you ever need an SDS then this one is cheap still (it's gone up since I bought it).

Hits hard, decent gearbox. I chiselled out a 9ft & 6ft trench of concrete to make a drainage channel - I gave up doing it with a sledgehmmer after 10 mins and drove out to Screwfix just for this.

Bit of overkill for hanging a shelf though.

Binned the cheap cordless shite now.

You guys with the cordless drills, you keep your batteries charged all the time, right?

Two (or more) batteries - that charger faster than I need them. And a quick charger.

Plenty of cases where battery power is more useful - though I do currently have 1.5kw of mains in my van, so can power a lot in the middle of a field anyway if needed.
However; say up a ladder, cordless can be a load less hassle - also tend to be better balanced for one handed use.

my "worx" £50 with 2 batterys lipo budget drill spent the weekend drilling 6mm holes in a 24 foot RSJ and screwing 6x 100mm screws in the timber work without any issues or lack of power Shocked

I gave up spending more than £100 on battery stuff years ago as they last me years anyhow! also have bosh keyless hammer 240 drill about 20 yrs old and an Aldi sds £30 special thats about 10 yrs old

spend your money on good drills and bits!!

Like most tools, buy cheap, buy twice.

Anything B&Q branded is questionable quality.

I've got a 10year old Makita 14.4v that's done me well and been well and truly abused. Sure it's a bit battered and one battery had died, but as I'm not using a drill as much on a daily basis now, it's not worth chucking out and so only having one battery isn't really a big deal, nor is the 30min charge time.

Buying a cheap drill to use as a bit driver for jobs like flooring or fitting cupboards is still worth doing too, as I've got a 15yr old homebase cordless that's ideal for use as a driver.

Money spent on good bits is the best way to go as mentioned.

I've been using one of the cheaper 'knock off' rechargeable batteries in my ryobi drill and it seems the same as the original batteries. I haven't done any controlled testing, but seemed to work well and they're only about 1/3 - 1/2 of the price.

For a cheap drill these are good below, used it to install a garage defender drilling out three holes for the bolts in thick concrete. It doesn't really grip the bits. However for a stop gap it works great. Easily enough for most home diy project.

So you've drilled 3 holes with it, found it doesn't grip the drill bits and its still "good"

No, that's wank.

Will it fuck. Drill doctors are trash. Restore your drill bits with a grinding wheel, or replace them.

It fucking will.

Not many folk have the required competence to re-sharpen a drill bit.

And I am including time-served mechanics and Electric Ians in that bundle.

A drill doctor takes all the doubt out.

Why would you say 'do they fuck'? Have you used a drill doctor?

Just asking.. Crying or Very sad

I have used one, and it gets a drill bit nowhere near 'back to a factory finish'. It'll put an edge back on a drill bit, but I wouldn't class it as a good edge. I fail to see how it's so hard to hold a drill bit against a grinding wheel at the correct angle, and then gently turn it using the other hand.

Only for the hammer action it doesn't grip going through concrete using one to put up shelves or to do any other form of home diy for £25 then its worth the price. You could use this for months then upgrade in the future when you really need to.

Better than my makita at the moment which needs a new chuck.

No diss to you Sir but it does need a little practice to use the drill doctor. (A little practice)
I sharpen bits with bench grinders and with angle grinders (in an act of desperation) and I will defy anyone to do it better than me on a wheel but the 'drill doctor sharpened' bits cut much better and the edges lasts longer.
And when set up it take seconds for a guaranteed edge.
There are some specialised edges they cannot dress but general jobbers are simple.

I know for a fact that 'most' people who use drill bits do not know even the basic rules of sharpening a drill bit. They hardly understand material properties so drilling holes is a bit of pot-luck for them.
If you go to any workshop and have a shoofti through the 'drill bit box' I promise you will see horrors in there.
They buy new drill bit sets. It is simpler than understanding the rules of sharpening.

There are fewer folk know how to get a sharp edge on knife so how can they be trusted with a precision cutting tool that has two edges?

I've worked in a workshop for 5 years and still can't consistently sharpen a bloody drill bit Laughing

I can do a passable job for drilling a quick hole, but more often than not it'll be doing more work on one edge because I've ground it slightly wonky. If I'm drilling something precise on a lathe/mill I'm enclined to reach for a new bit than trust my own! More practice needed!

That said, cheap new bits can be worse than my attempts, you definitely get what you pay for in that regard!

I can sharpen big drills, 8ish mm upwards. It's the little ones that I am shit at doing, probably because I can hardly see the edges!

Anyway, the small ones are as cheap as chips nowadays, a couple of quid for 10 so I always have a good stock at home.

I will sharpen the larger sizes just because they become a bit more expensive. Like everything, it's just practice.

My cheaply homebase one grips the bits after drilling all sorts of ahit going back about ten years

I just keep a mid-range cordless drill (£70 Bosch) and a cheapo corded hammer action for big holes in hard stuff. My Dad gave me a cheap SDS drill but it broke whilst trying to get a seized bit out. I'd rather spend out more cash on good drill bits rather than the drill.

Personally I'd not bother with a biggun, unless you have enough heavy work to justify the cost of a half decent one.

I've got a 10.8v Dewalt twin set.

It's great for most jobs round the house, although for big/long holes it ain't up to it. I also have a Cheap S/H Dewalt mains Drill to cover what the 10.8 isn't manly enough to do. My mate has the top of the range Dewalt 18v twin set. I had tried to drill a 15mm hole through an external wall with mine and it bearly touched it, his pissed through it, but his cost over twice as much.

The 10.8v Impact Driver is excellent too. I used it the other day to drive ~10 10cm 5mm screws into a fence and it did it without breaking a sweat. I boarded my loft with it on one charge I believe The only thing I've found it can't do is crack wheelnuts off. When Ben (Binge) came to do the Clutch on my car I noticed he had the same one and said he has been using it for years as a mechanic.

The 10.8 stuff is cheaper and lighter and I think better round the house. The downside is there will be a few things it can't do. Once you find somethign it can't do go out and a cheap corded one.

TL;DR for the average homeowner, I think a 10.8V set is best for convenience/price but you may need to get a corded to do something a bit harder.

P.S. you definitely want an impact driver. I wasn't sure I needed one but have used it so much.

This indeed - after I got mine I tried just driving a 3" screw in to and straight out again - the resulting hole was left smoking.
And without the 'kick' from a normal drill.

Note that you can use a a larger impact wrench with a 1/4 hex bit adapter as an impact driver.
However, perhaps not on full power - even the fairly puny 400nm Ryobi twisted the PZ2 bit - did drive it in very fast, however Smile.
