to tell you the truth ive only looked on the net and screwfix , but i guess your right, i will go dowm the wholesalers later.
 
6mm (or is it 6.3mm?) drill bit in vice, apply grinder for 3 seconds, flat created before your very eyes. If it's too long apply grinder and crop to suit.

Does anybody sharpen their own drill bits anymore or am I the only one left?
 
I do ;) although sometimes with more success than other times lol remember one night at work on my own with a blunt bit and lots of stainless to drill and normally the mech engineer does it for me..i went online and self taught myself using various websites but there wasnt a lot left of it by the time I cracked it lol

i hate blunt drill bits and allways sharpen them ,6mm fits a starrett and ijust put them in and tighten the screw ,but i never use a cutter without a pilot hole so it works ok :)

Some 'tradesmen' who should know better just don't understand that a drill bit is a cutting tool NOT a grinding tool! How many times have you seen some egit with a pile of conduit boxes to drill who's whacked the drill on full speed and is practicaly standing on the drill trying to get it done as quick as poss, bit smoking red hot and a pile of blunt ones in the bottom of the saddle bag they use for a toolbox?
Once you show them a feed/speed chart from a lathe they get the idea, they slow the drill right down trying to get the longest smoothest continuous piece of swarf they can and the bit lasts ten times longer. What's more, they find it's even quicker than trying to plasma cut their way through them!!:D
