For those of you who didn't know, Crucible has more or less gone out of business (if your service center isn't closed it will be soon). If your using any of the grades listed below, these are the AISI cross-reference grades. Boy, are we busy...can't keep toolbits or flatground on the shelves...

Ken, Thanks for the support!! But our inserts (Warner) are the High Speed Steel ones - Enco has the carbide. By the way, Enco inserts will fit our holder. Thanks Mike Warner Arthur R Warner Co.

Deere, Nice finish. It's a great feeling when you accomplish something you set out to beat. The tool bit (allegheny ludlum dbl) is probably M-4 HSS. Without knowing if it is a #2, #3 or #4, can't know for sure. But it's definitely a better grade than you received with your mill. I don't...

Just a note: If you grind a tool to 60°, THEN grind a back rake on it you have changed the 60°. Hold a triangle up looking straight on the cutting point. Now tip it away from you. The 60 included angle becomes smaller. Mike Warner

I still have some bars not accounted for. If the one you purchased is OK, please respond anyway. I need to get some sleep. The replacement bars and inserts are coming shortly. I appreciate all the support I have received over this situation. The response and sales of the newer kits exceeded...

To the people that purchased the 80° diamond (CCMW 2-1.5-1) 3/8 dia. boring bar from us (Arthur R. Warner Co.) at Cabin Fever. Please contact me for replacement. A small percentage was ground improperly on the top flat. Since this is the surface that actually locates the pocket, it is creating...

applescotty, You want to make the cutting edge as sharp as possible. If you look at the ground edge under magnification you will see mountains and valleys. These are what you want to get rid of by honing or polishing the tool. Be careful not to round off the edge that actually does the...

Hi Eric, Yes I'll definitely be at Cabin Fever as a vendor. I really look forward to it all year. Our booth is kind of hard to miss. It's done in red and black with a sign (Arthur R Warner Co.) above it. This year we are adding 14 new High Speed Steel Insert kits to our booth, and I'm kind...

Couple of things about Stainless: Don't baby it with light cuts or dwell your tool on it. Try to keep your tool as sharp as possible. If you use carbide, make sure the cutting edge has very little or no edge prep. Most carbide tools have a negative or small chamfer on the cutting edge to make it...

Thanks, There is a lot of interesting things on this Forum for sure. I have a good bit of reading to do. T70mkIII I have a couple of things I would like to do, my problem is finding the time. I thought I would have more time this winter but the shop was pretty busy. Thanks Phil, glad...

Hello all, Just joined and thought I'd introduce myself. My name is Mike Warner and I've been in the metal working industry for 31 years full time and I still love it. I say full time because that's when I graduated high school, but my dad had me running a Warner & Swasey #3 Turret lathe when...
