This pilot is ground from carbide material to provide the benefits of the carbide but does not have the cutting teeth ground into the end. Great for the user that is concerned about brass galling but doesn't require the cutting feature for doughnut removal. Even though the coefficient of friction of brass on carbide is less then that of brass on steel you still need to use lubricant on the pilot.. FeaturesMade Specifically for the K&M Neck Turning ToolCarbide reduces friction caused while turning brass to reduce the chance of galling
