Best Process For This Tapered Cylinder Cone Taper Mill
Mar 09 2020 this makes it a good taper reamer but a crappy tapered end mill putting a helix on it is a good idea but id make it a left hand helix like a taper pin or sprue roughing reamer i fully agree that if it can be made with through tool coolant that would be a major bonus last the ball diameter is only 011142 so its still fairly small
