This is a 3/4 size diamond router bit. This is a rare type with slits on the grinding surface, making grinding work comfortable! I was worried that the cross-section would be rough, but it surprisingly finishes beautifully. It can be attached to common routers such as Gryphette, Inland, and Glastar. It will be sent by Nekopos (a Japanese delivery service). #stainedglass #routerbit #routerblade #diamondbit #stainedglassmaterials #stainedglasstools #stainedglassrouter #Gryphette #Inland #Glastar
