Does anyone know where I can buy wood drill bits (lip and spur type) in 3.5mm and 4.5mm sizes for clearance holes for no6/3.5mm and no 8/4.5mm woodscrews? They are the commonest sizes I use, but all the on-line sources I can find only sell sets or individual bits in whole mm sizes - typically 3, 4, 5, 6, 7, 8, 9 and 10mm.
I've searched extensively on-line without success. One or two sites used to list them, but they were both very expensive for single bits AND out of stock - possibly permanently - and I can't even find a listing now anywhere - not on Amazon, not on eBay, and not from a general Google search for 3.5mm wood bit or lip and spur bit.
An old post on this forum (from 2009) said that Axminster Tools used to sell a set in 0.5mm increments, but the link is dead, and they don't any more have ANY half-mm bits, nor do they know where to get any. The nearest I could find at Axmister was for 1/8" and 3/16" wood bits, but both are the wrong size to fit well - too small and too big respectively, though 3/16" is not hugely too big.
And I've seen ONE set for sale with half mm increments from 3-10mm for £25-odd, but that's very expensive just to get the two sizes I want, since I already have two sets of 3-10mm bits in whole mm sizes.
Any known sources or suggestions for where to look, please? Or better search terms to use?
