Help me sharpen my drill bits
#1
I have this set of colbolt drill bits http://www.toolstation.com/shop/p94153?table=no but most of them are now blunt.
Can someone recommend a sharpening gizmo to re grind them, I do have a bench grinder and stone but I can never seem to get the angle right.   
I don't do rain or threat there of. dry rider only with no shame.

If you are just having problems getting the angle right try something like this.

I assume you have a pedestal grinder, you need to buy silicon carbide wheel for it.

If you've got a decent bench grinder you've got everything you need fella.

You can check the angle if you hold the business end of drill bit between 2 nuts  :eek  it forms the correct angle 120 degrees.

Thanks for the help so far, looks like i need a  silicon carbide wheel, mine is more like a grinding stone and a bit rough.
I have seen in the past an all in one thing where I can just poke the bit into it, but thinking they are probably rubbish.

it'll be fine if you are careful. Sharpen drills all the time at work on shitty indented grindstones due to welders sharpening their tungsten tips.
