How To Grind a Drill Bit For Brass? - EdK - 08-30-2013 Tom, How about a "How To Grind a Drill Bit for Brass" video?

Tom RE: How To Grind a Drill Bit For Brass? - Micktoon - 08-31-2013 I will second this request Ed , people keep saying things like knock the edge back for drilling brass , but not give any detail of what exactly they mean by it ...................... I am sure all will become clear once Tom gets to work on a video covering the topic Just when ever Tom, no pressure Cheers Mick. RE: How To Grind a Drill Bit For Brass? - TomG - 09-01-2013 Would tomorrow be alright Mick, I'm a little busy SLEEPING at the moment. I actually thought of a little demonstration of what a standard drill bit does when you try to drill brass or plastic, so this should be fun.

Tom, I, for one, KNOW what happens when one tries to drill brass or plastic with a nice sharp "standard" drill bit. Recalling the memories would not be fun for me. RE: How To Grind a Drill Bit For Brass? - Sunset Machine - 09-01-2013 Umm.. I just take a stone to the edge and put a wee bit of a negative rake on it. I guess that's hard to picture. Tom? Where's that video?! :) Oh hey, another stunt with a stone is to round the outer tips a bit. It's called a poor-boy's reamer. :) :) RE: How To Grind a Drill Bit For Brass? - Micktoon - 09-01-2013 Hi Tom , I like the sound of the demo, I know what will happen , hence wanting to find out how to sharpen drills to stop it happening ..............looking forward to the video. Thanks agin for taking the time to do them Tom Cheers Mick RE: How To Grind a Drill Bit For Brass? - TomG - 09-01-2013 Here it is as promised. Of course Mick's probably busy sleeping now. Tom RE: How To Grind a Drill Bit For Brass? - Micktoon - 09-02-2013 Hi Tom, I am awake now and watched the video , top marks as usual, I was surprised to see the plastic lift out the vice I think I have been lucky so far after seeing that! It looks more straight forward to alter the drill bit anyway so I will do some spare drills and keep them for brass. Thanks again for posting Tom Cheers Mick. RE: How To Grind a Drill Bit For Brass? - LJP - 09-02-2013 I knew it was dangerous, i didn't know how to solve the problem. I always used more clamps. Thanks for the knowledge! This could not be more simple. |
