Gemini Taurus 3 Separating Blade Kit The Gemini Separating Blade is a multi-purpose diamond blade with an aggressive grit designed specifically for internal cutting. The Separating Blade is omnidirectional and cuts at the same speed and kerf in any direction. The blade opens to slide material inside the blade to make internal cuts without using an entrance cut Features For internal cuts, omnidirectional Made from a stainless steel wire and coupling, which allows the user to open and close the blade for easy internal cuts After drilling a small starter hole through the material, this blade gives you the ability to open the blade, slide your material inside, reattach, and make internal cuts with no entry point Excellent for cutting glass, thin tile, stone, shell, nonferrous metals, hard plastics such as acrylic and lexan, and anything that has a similar density to these materials All Gemini blades use the same belt and grommets. Blades are interchangeable with the same belt and grommets and do not need to be changed unless they are excessively worn Always let the blade do the cutting. Forcing the blade through the material quickly will cause a slower cut and shorten the blade's life. There is an optimum speed for each blade in each material; you can feel it while cutting. Sensitivity to this causes exceptionally long blade life - try to find the sweet spot where you get maximum cutting speed with only minimal pressure It comes with 2 orange groove grommets (part number 0485) Note: Do not use for ceramic tile, 3/8" fused glass pieces, or thick material in general Gemini Taurus 3 Separating Blade Specifications Blade Shape Round, 0.072" Diameter(Note 1/16" is 0.063" and 1 mm is 0.0394") Material Thickness Capacity 3/8"1/8" art glass, 1/4" soft wall tile Grit Aggressive Average Blade Life 40-60 hours
