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.

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. ____________________

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
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!! ____________________ Current bikes...cbr929, KDX200's, Rd125lc mk2, RGV250's |

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.

No, that's wank.

Why would you say 'do they fuck'? Have you used a drill doctor?
Just asking.. |
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. ____________________ '10 SV650SF, '83 GS650GT (it lives!), Questionable DIY dash project, 3D Printer project, Lasercutter project |

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
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 am a bellend, I am a man of constant sorrow, I am a gummy bear, I am a rock. |
