015 Astra Elite, Summit tool and cutter grinder 

Very good learned alot keep on with your good work Willie South africa

Although difficult geometries, all well explained. Like it.

Nice little grinder👍 looks like a very universal setup. Just a note. Not all saws have evenly spaced cutting edges. Most are offset a few degrees from one another to reduce the chance of chatter. It's often not noticeable by eye. I've sharpened them the same as you just showed in the past. The finger rest needs to be on the tooth your grinding. It makes the setup harder but is the proper way in most cases. I like the jig for the single flute cutters. 👍 Thanks for sharing

Hello The video is very helpful in understanding the range of possibilities of this machine. I also have exactly the same machine The main use is sharpening drills It is without a doubt an important tool for a mechanical workshop

Just found your video, great overview. I just picked one of these up. I am missing the drill sharpener attachment. Would you be willing to share up close pictures of that? If so do you have contact info? Thank you and great work on the video.

Interesting video and tool

Bonjour, je possède la même machine Elite, le seul accessoire que je n'ai pas c'est pour affûter les forets !!!! (dommage)

Hi, thanks for posting the video. I have one of these machines but unfortunately I dont have any attachments that go with it. I wonder if you would be so kind as to show the method of mounting the stones on the shaft that has the taper? I am wanting to make some arbors but just dont know which way to go about it.

Hi from the UK, I just bought one of these excellent machines and love the single point sharpener attachment you made. Tjats really smart :)

I wouldn't index off any tooth but the one you're grinding. You're relying that the spacing of the teeth is perfectly equal. I would reverse the cutter direction. Put a hooked finger to get the finger out of the way of the grinding wheel. Set the finger on the center highth of the work head and under the tooth you're grinding . Use cup wheel and tilt the spindle head to the desired primary clearance angle . Tilt more for your secondary . This way you know your exact clearance angles . Adjust your wheel highth as necessary to get clearance to keep from hitting the tooth behind. This is the way I have done it for over fifty years. Nice grinder I have never seen before and I have seen a few.

Hello Don from Aus. I like your vid and now I see you are a steam nut like me. All the best BC.

That is one handy, versatile tool. “Borrowed from Dad”? Will he be asking for it soon? Looks like it fits real well and you have made improvements. Just saying.

I like your videos with your voice describing what you're doing. Nice job!

Great video.. Narration, explanation, etc. Not a lot of videos out on cutter grinding.. Steve has shared some great videos. Thanks for sharing.

i'm a tool and cutter grinder. you will achieve better concentricity if you bring the wheel up over the top and grind the flute that the finger is engaged in. dress the bottom of the wheel flat first. That 5c to r8 adaptor is awesome by the way

Hi Donald. Great video and very informative. On your shelf there is a folder "Set up for grinding milling cutters" Is this available? and does this relate to the Astra machine? Thanks Rob
