What type of grinding wheel is used on a Darex TR70 tap ...
I asked the seller & he said that it used a cone type grinding wheel. On my TR70 motor it says E-85,E-90,TR. Which tells me that the same Darex motor is used on the darex e90 & e85 endmill sharpeners too. I do have an E90 but the motor looks slightly different. My E90 also uses a cone type grinding wheel.
