Thin sintered diamond saw blade


Blade Specifications:

The extremely durable Hi-Tech Diamond thin sintered diamond saw blade is manufactured using premium diamond grit (325#/400#) that is secured into a metal bond, extending the full depth of the rim. This blade uses sintered technology, which increases their life span compared to notched rim saw blades because diamonds are continuously exposed as the edge of the blade wears away, cut after cut. Thin rims make these blades suitable for cutting and trimming material such as quartz, topaz, glass and fine agates.

All saw blades have 5/8" arbors and come with 1/2" bushings.

Important purchasing note: The 8" saw blade comes either in red or black. This does not affect the performance of the blade. 

Please note: These diamond saw blades must be run with a lubricant such as water or oil. NEVER run dry! We recommend using a good quality cutting oil with these blades. To enhance the performance and life span of these blades, abide by the recommended operating speeds and spin-dry your blade after use to prevent any rusting.

I think my saw blade was improperly refurbished.

I ordered and received a thin sintered saw blade. I'm accustomed to these blades being covered in red paint, with only the diamond coated portion being unpainted.

The most recent blade I received looks like it had been thoroughly used. All the paint on the blade, except for the portion adjacent to the arbor was missing, and the diamond section of the blade looked used.

This happened to me once before. I made the mistake of not opening one of these boxes with the blade for more than several months after ordering it, and saw a blade in a similar state. I thought maybe they just changed their design, and the blade would still work fine. I was wrong.

The last 2 thin sintered blades I've ordered have been this way. For whatever reason, I haven't had this issue with the thick sintered blades. I plan to submit a customer service request.

Love it

I slice and dice regular rocks for my art. These work better than others I've tried from Amazon. Fairly quick shipping. Packaged well. Customer support is excellent. Picture is what I do. Rocks, rocks and more rocks.

Great blade!
