How do you guys sharpen spade bits?
With files or maybe a sharpening stone?
I've tried with files, but it doesn't seem to get as sharp as I would like it to be.

Sharpening of spade bits?
Re: Sharpening of spade bits?
A file is faster if the bit steel is soft enough. Mine is hard enough to require a stone, though. Make sure it is ground correctly first otherwise you will spend a year working on it with a stone without ever getting a sharp edge.Charl wrote:How do you guys sharpen spade bits?

What you need is something like this 4 Grit Diamond Grit Hone Knife: http://www.mlcswoodworking.com/shopsite ... ories.html

Putting it succinctly, supply and demand. There are a shitload of Americans (especially in America ) with lots of retailers competing for their scratch. Plus, inflation has kicked the snot out of the SA Rand.Charl wrote:Wow! Why is it that the prices over there are so cheap! Something like that over here would probably cost in the region of $30!?
You use a fine grit wheel to touch up the cutting edge. It shouldn't remove much material, unless you really lean into it, in which case you'll ruin the temper anyway.Charl wrote:If you use the bench grinder to sharpen, wouldn't you have to get new bits every month or so?
