Posted on Jan. 28, 2015 by Stuart Lees on his Australian woodworking website, Stu’s Shed “While woodworking often doesnt require extremely fine and/or accurate holes, there are times when a fine set of drill bits would be very handy, and when it comes to fine bits, they dont get much finer than these sets from Zona Tool. They are supplied in Australia by Professional Woodworkers Supplies. Whether you are model making, making jewellery, working with wood, metal, plastic, glass, ceramic, even stone, the ability to drill incredibly tiny holes is achievable. But what do I mean by fine? How about 0.3mm to 1mm in 0.05mm steps (then from 1 to 1.5mm in 0.1mm steps)? 0.3mm, or 300µm. Sure, that doesnt sound too small when talking about sanding, where we are working with particle sizes in the 10s of microns (or less), but these are drill bits we are talking about! To put it in scale, consider the humble Australian dollar coin. It may not be angels dancing on the head of a pin, but here are the three finest drill bits in comparison. Of course you wont be mounting these bits in your standard power drill! So in the first photo, you can also see a couple of bit holders/drivers from Zona as well. One is double ended for larger and smaller bits, the other is a twist-drive, which can hold the finest bits. None of these are particularly expensive either, with the drill bit set around $25. They are available in metric and imperial, and interestingly, the blue box above are diamond coated bits, which is why glass, stone, ceramic etc are also able to be drilled with this precision.” Read the whole review at: http://www.stusshed.com.au/ photo credit: http://www.stusshed.com.au/
