Norton 3X Blue Grinding Wheel
ItemĀ #: K3SG
Price: $42.99 - $52.99
  
 


This is the wheel that wood turners have been asking us about. The K-Grade of this wheel means it is a harder wheel. The harder grade is great for sharpening high speed steel tools without wearing grooves in the wheel. If you're a turner, you know what we're talking about. This harder grade comes at a price. We recommend the softer I-grade wheel for high carbon steel tool grinding applications. This wheel is available in a 46 grit for coarse work and a 80 grit for a little finer work. The 8" wheel has a 1" arbor hole with bushings for 7/8", 3/4" and 5/8" arbors. The 6" wheels have a 1" arbor hole with bushings for 7/8", 3/4", 5/8" and 1/2" arbors.

Q#. Do you recommend this K grade wheel for turning tools?

A#. Yes, turning tools are made of high speed steel. High speed steel has greater heat resistance so the harder compound of this K grade wheel won't overheat the tool. The harder wheel is recommended because it will not groove or lose its shape as a softer wheel might do with turning tools.

Q#. Is this wheel good for high carbon steel tools?

A#. No, we don't recommend it for high carbon steel tools. The harder wheel will more easily overheat high carbon steel found on tools such as chisels and plane irons. For high carbon steel we recommend the softer I grade.

Received my Sharpening System today,(Norton IM83) and I've got to tell you that I am excited about using this product. I've been in the meat cutting business for 45 years, and as you can imagine, I've used allot of different types and styles of sharpening equipment. I have had 3 Norton Multi-Oil Stone units in my lifetime, and then I see this IM83 and I think that this is what I need to carry with me when and wherever I go. I just LOVE this little box full of expertise equipment to keep me sharp and at a razors edge. Thank you for the service, it was fast and easy, and I received it within 3 days of ordering. I know knives and how they work, and I can't wait to start putting that edge on my "other" knives I own.
