    Digital caliper with "circumference button"?

    I just bought a cheap digital caliper and was surprised to see an extra button marked (L/C). Never seen this before so hmm, what does this new button do? Well it turns out it just multiplies the reading by Pi (3.14159...). Ok I get it, you can put the calipers on a diameter and have it read the...

    Cooking spray-oil as a drill lube?

    I was assembling some flat pack shelving/storage for the wife today and I decided to add a couple of extra screws on something I thought could be a bit more secure. So I needed to drill a few small holes in some metal brackets. I was in the kitchen and didn't have anything at hand for cutting...

    Drill Press. Runout vs quill slop?

    I've noticed that many of the lower cost Chinese drill presses these days seem to have a lot of quill slop. At least compared to older Taiwanese models I've seen. Recently I bought a cheap DP and it runs ok and gets the job done, but it has way more slop than my older Taiwanese one. I thought...

    "Dwelling" sometimes when I'm drilling steel?

    When I'm drilling steel on a DP, if it's a relatively deep hole and I have to peck it (or withdraw the drill to clear the chips), then when I recommence drilling it often feels like the drill bit just dwells for a while and doesn't start cutting straight away. Even when it's just mild steel and...

    Went to Aldi to buy milk and came home with a Drill Press.

    No joke. Had no milk in the fridge one night last week so I took a quick trip to an Aldi supermarket to get some. Had no intention of getting anything else, but came home with 3L of milk and a small drill press. :o As far a I can tell it's this one (EinHell BT-BD501) rebranded...

    Is this the stupidest Amazon review ever!

    I clicked an ad leading to a product on Amazon a few days ago and could barely believe how ridiculous one of the reviews was. The thing that drew my attention to it was that it had just three reviews, two giving the maximum five stars and one giving the minimum possible 1 star. So I just had to...

    Drill Press tables. Slot type differences?

    Looking at small cheap drill presses, I notice that there are two popular styles of slots in the tables. There's the "X" (radial) type as shown in the first attachment, and also the straight (parallel) type as shown in the second attachment. I'm just wondering what particular...

    What type of "pointy" drill bits are these? Pilot,Brad,Spot weld?

    A while ago I bought a box of used drill bits online, mostly to get some larger sizes that I didn't have, but also to have some to practice sharpening on. The majority were just 118 degree regular style sharpened, though some where sharpened to odd ball angles like 90 degrees or even really...

    Drill has lost full speed. Faulty trigger unit?

    I've got an older 24V nicad drill. It's a pretty cheap **** GMC brand, but I've kept it because it's got a 13mm chuck (my newer drills are only 3/8 or 10mm). Yesterday however it up an died on me. Well not totally dead, it runs as long as you don't try to go full speed. When you depress the...

    So this is what a burnt up drill bit looks like!

    First up my apologies about the lack of a "before" picture. I wasn't thinking about making a post regarding this issue at the time. I bought a bunch of second hand drill bits from ebay, just to get a few larger sizes that I didn't have and to give me something to practice my sharpening skills...

    Critique this guys drill press technique.

    A bit long winded, but I thought this was an interesting video. I've got to give the guy 10/10 for effort, burning up all those nice drill bits. But some of his technique really made me cringe.:wtf: What do you think?

    Wite Power (cordless tools).

    The instructions on these Chinese nut drivers told me to use "Wite Power" cordless tools. :rolleyes: I only had my green ryobi tools with me at the time, but fortunately they seemed to work all the same. :p

    How often do you come across 17/32" nuts/bolts ?

    This is something I sometimes come across with old garden type equipment. TBH I'm not sure if it's actually 17/32" or some other oddball size, but it's about 13.4 mm and I've got nothing (neither spanner nor socket) that fits it. Last instance was today when my wife asked me to pull the tray...

    Hep with gassless mig vs stick welding.

    Currently I've only got a very cheap little AC stick welder that's pretty crappy. I don't use it a whole lot, just every now and then to (try to) repair stuff. The problem is that most of the time I'm trying to weld something thin and have to have the current set fairly low (to avoid blowing...

    Black oxide drill bits and land/margin geometry?

    This is something I've noticed for a long time and never really understood the reason. I actually had to google what these parts were called (land/margin) to ask my question, so let me ask away. :) Almost every time I've looked closely at black oxide HSS drill bits, the part near the leading...

    Drill sharpening. Don't hate it when ...

    You grind each edge then stop to take a closer look. One edge is slightly longer than the other. Also, one side is perfect but side the other needs a touch more work. It's always the longer side that needs more work. :o

    Mystery of the universe #427: Why are bent nose pliers smooth jawed?

    I just bought a little 4 piece mini pliers set yesterday because they were on sale for a ridiculous price. When I got them home I first thought that the bent nose pair had missed a manufacturing step or something, because the jaws had no grooves or lines or anything to aid grip. They are...

    Impact driver 1/2" square adaptors. Max torrque??

    This thread concerns those 1/4" hex driver to 1/2" (or 3/8") square adaptors, like this type of thing: http://www.amazon.com/dp/B000YQ341C/?tag=atomicindus08-20 Looking at some recent threads here I see that some people mostly use their (electric) impact driver as an impact wrench using one of...
