New one on Amazon but a bit pricey! (but you probably know about that one.)

I had a few thoughts about grinders, not that I'm trying to persuade anyone to my point of view.

1) The best modern, cool running grinding wheels now available make a slow speed 1800 RPM grinder far less essential for tool grinding than it used to be. And the higher speed 3600 RPM wheels have a fanning action that greatly helps to keep the steel cool.

2) The bent steel and cast iron tool rests that are supplied with Baldor grinders are functionally about equal, but they both pale in comparison to aftermarket ones like the Veritas, for example. So why worry, or spend the extra money to get the cast iron?

3) The moderately priced Baldor 602E grinder I wound up purchasing has one very important feature that the more expensive models do not. The motor end bells, wheel guards and base are all made of cast aluminum, so the machine is lightweight at just over 20 lbs. This allows me to readily carry it outside to do my grinding, keeping the grinding dust out of my living space. Despite the fact that the wheel guards have ports molded into them for hooking up a vacuum collector, you cannot simply suck sparks into your shop vac without creating a great fire danger.

Hi Mark,

I'm curious about the "cool running" 3600 RPM wheels you refer to. Can you provide more info.

 

I have a Wissota 1/3 HP 6"  Mod E6, 3450 RPM on a matching 4" sq  steel stand with a 14" base pad.

It has been very reliable since purchase over 15 yrs ago, but I often wished it was the slower speed.

Also have a Makita Mod 9820-2 (7 7/8" dia  horizontal wheel) and , of course, a hand grinder.

 

( For lots of chisels and gouges by E.A.Berg, Addis, Charles Buck, Witherby.  Japanese makers, etc. which I'll have to get organized someday  )

For example these: http://www.leevalley.com/en/Wood/page.aspx?p=32981&cat=1,43072,43080&ap=1

Or these: http://www.leevalley.com/en/Wood/page.aspx?p=62012&cat=1,43072,43080&ap=1

And you might look at these: https://www.toolsforworkingwood.com/store/dept/TH/item/NO-WHEEL3X.XX

You will probably notice that these are all Norton products. Also, the letter grades refer to the friability of the stone bond, with softer bonds making for cooler running stones. A lower letter grade, e.g. "H", will be softer and cooler running than a "K" grade stone. But they're all an improvement over what used to be typical.

Thanks for the quick reply!

 

 I will give the 80x Wheel - 6" x 1"  08M18.01 a try.

I bought new one.

 

Thanks.

I have an old grinder by KEF 8" wheels, which  i bought on ebay for £15, great machine which are still made but  cost a small fortune. I use an O Donnell ruby grinding wheel like this (80 grit, 1/2 way down the page)http://www.toolpost.co.uk/pages/Grinding_Systems/O_Donnell/Grinding_Wheels/grinding_wheels.html  and a microcrystalline higher grit wheel ,8" version (fine grit)  http://www.peterchild.co.uk/grind/bluewheel1.htm.

Both are great despite the high speed of the grinder and i never have a problem with burning the edge on any type of steel as long as you dont put too much pressure on the tool.
