I needed to get a couple of 2.0mm drills but ended up buying this, along with a few other bits and bobs. DrillsFifty drills for £ 2.12 inc postage!! If this originated in the UK, you would need to spend £2 on the postage BEFORE getting any goods. Totally ridiculous Regards, Steve |

"How ridiculous is this?" - you'll probably find out when you use them! About 6 or 7 years ago, I bought some similar drills at a Model Engineer Exhibition from a well known London dealer. I soon found that they were only fit for drilling aluminium or plastic. When used on steel, they soon lost their edge and started to bind in the hole - in fact 2 of them were so soft that when they seized in the hole, they reversed the direction of the flutes!!!
regards,
Eddie.

You may well be right, Eddie, but I've had many items from Banggood before and had no complaints. Even so, at 4p per drill, they only need to drill one hole and can be thrown away. The ultimate in disposable tooling.  Regards, Steve |

Steve, I have to agree with Eddie. I have some small ARC Eurotrade drills which purport to be of better Chinese quality, but examining the points under a glass shows really poor edge and angle grinding, resulting in inaccurate hole size, and running their drills at the recommended speeds is NOT to be recommended. I have some British made Draper drills which, by contrast, are a joy to use! The only place you find free cheese is in a mousetrap... |

I will report back after trying them out. I doubt they'll arrive before Christmas, though.

you can laugh, I have had some lathe tools from Banggood, and am very pleased with them.

Today I received a dial test indicator and magnetic stand for $17 postage paid from China. I needed the dial test indicator to be able to in a 4 jaw chuck set up a small bore to be concentric with the lathe axis, my existing dial indicator couldn't accurately undertake this due to insufficient space in a small bore. The stated accuracy is 0.001mm which I didn't consider to be an important issue because like my dial indicator will be used mainly as a null indicator when setting a small bore concentric to the lathe axis in the 4 jaw chuck. However, I now realise that a dial indicator and a dial test indicator can be used for measuring, not as a direct measurement but as a comparator, ie zeroing on a known say 1" gauge and measuring the item under test to see how much greater or lesser it is to the standard gauge. The limitation being the measuring range of the dial or dial test indicator. We live and learn.

Brian Brian The DTI is very useful for that type of work, but make sure that the thing is set up exactly at right angles to the test piece, otherwise you will be measuring the hypotenuse instead, which is not a good idea...

Thanks John,
that very point you make was included in the youtube video that I watched and was demonstrated by altering the angle from being perpendicular to the face of the item under test, the expected reading of 0.005" was 0.008".

Following this post I ordered some miniature slitting saws at an amazingly cheap price,they look excellent.
These are HSS and various diameters up to 35mm dia ,ideal for use with my BCA jig borer.
I had to make an arbor to hold them and discovered that the mounting holes vary in size somewhat and some are even elliptical.
Upon use they could almost serve as eccentric sheaves and after one short cut in mild steel the first cutter is knackered.
Admittedly the ad does say for wood or soft metal but nevertheless they are what you would expect for the price........crap.
Dan.

Following up after a post on Andy's thread, the drills I bought that started this thread were total rubbish. But at four pence each, I only needed to drill one hole with each to break even. I have since drilled sixty two holes with one of them, so I'm ahead of the game. Regards, Steve |

Regards, Steve I've just spent the afternoon amongst my drill boxes, sorting the wheat from the chaff, and found an unopened bag of about 25 1.5mm drills. They are all like the one in the photo, so poorly ground that you couldn't even drill one accurate hole and then discard!! John  DSC00322 by inkaboat, on Flickr |

John I quite agree, John, they are total rubbish and I would toss them out too. However, my total rubbish was able to drill a reasonably accurate hole. Can I start this one off, please? My rubbish is better than your rubbish... Regards, Steve |
