4 Inch x .020 x 5/8 Inch MK303 Medium Diamond Blade
The MK303 Diamond Blade is a medium cut sintered diamond blade excellent for cutting quickly through your glass with a minimum of edge chipping. A good balance between quick cuts and clean edges. Oil is not required for use when cutting glass. Water is the only coolant required for glass cutting with this blade.

The MK-303 Professional grade diamond blade has been designed for cutting rare and valuable materials when waste needs to be held to a minimum and speed of cut is essential. The MK-303 produces smoother cuts, lasts longer and cuts faster than notched rim or plated diamond blades. While MK lists these blades as requiring coolerant to properly operate, with glass the only coolerant you need is water. Coolerant is only required when using these blades for lapidary cutting.
