I bought one of those ultrasonic pest repellers once because the wiring to my decking lights had been chewed through. It drove my eldest lad wild because he could hear it, the freak! Maybe he's a superhero?
I was once trying to drill a hole through the suspension leg of my old car so I could put a nut and bolt in as the captive nut had sheared off. The only drill bit we had had gone blunt and we didn't have a bench grinder. It was Sunday afternoon so nothing was open back in the day.
Cue me...
Just thought I'd throw in a few points here. Only skimmed the thread but hopefully, my input might help.
Every torque screwdriver is sold with a calibration certificate. The standard they are manufactured to states that they should be calibrated every 12 months or 5000 clicks (whichever comes...
Masonry bits are rotating chisels, they don't 'cut' as such. Therefore the progress in masonry is made using a hammer action.
In drills with 3 jaw (keyless) chucks the hammer function is actually called 'percussion' and is not heavy enough to drill holes in the denser masonry materials such as...
Little tip - copy and paste the product code from the Screwfix page/website/advert and punch it into Google, click on the shopping tab and if the only options to buy that particular model come up as Screwfix, Amazon and Ebay you may have a clue ?
On your annual inspection from whichever regulatory body you belong to you should, in theory, be asked to produce your torque screwdriver and a valid calibration certificate. I know from talking to electricians that this doesn't happen all the time.
However, taking it to the nth degree, what if...
It's a torque checker, not a calibration tool. It doesn't really measure and record readings rather it indicates that the torque screwdriver is working correctly. It does not remove the need for annual calibration...
The standard that torque screwdrivers are manufactured to (EN ISO 6789:2017) states that the first re-calibration should be carried out 12 months after first use or 5000 actuations (whichever comes first). How many people are going to actually count how many times it has clicked and document it...
It seems to be the norm now so that they can weedle out the malingerers and hypochondriacs.
The best way to combat it is to either say "I'd rather not say to an untrained person if that's all the same" or announce loudly in the packed waiting room
"Well one of my balls has swelled up to at least...
I work for a power tool accessory manufacturer. My boss asked me if we needed to produce a Plus/Minus impact driver bit as he noticed that that was one of the ones not in our range.
I said "No" ;)
Drilling through concrete using an SDS drill and good quality bits is not a nightmare.
Drilling through concrete with a combi drill and percussion drill bits is;)
You could do worse than to try Duro. They are experts in diamond cutting stuff. Their website is here. Duro Diamond Cutting Blades, Circular Saws, Grinders, Drill Bits & More - https://www.duro-diamonds.com/
Interestingly, the water is marketed as "dust suppression" rather than blade cooling...
A lot of the time, it's not the bit that's the problem, it's the machine. Straight shank masonry bits are obviously used in machines with 3-jaw chucks. To the majority of users that means a combi drill. The impact energy of combi drills is vastly inferior to SDS machines.
On a combi drill, it's...
Back in around 1989 whilst sitting in the dining room of my ex-girlfriends one night there was a crunching of the drive gravel and a crashing noise from outside. I shot to the window to see what was happening (my ex-girlfriend never moved). "Bloody hell!" I exclaimed and she said "what's up?" I...
