66 Deg - HSS Breech Tool (3/4" Dia)

It is important to have a perfectly concentric breech radius and angle, not only because it allows for a smoother feed while loading your cartridge into the firearm, but also in that it assists in the later steps of the reaming process. Made from high quality Carbide or M2 steel you can rest assured that the first point of contact will be both accurate and consistent. Supplied with a nominal sized pilot bushing. See our bushing selection HERE for additional bushing size options

NOTE: All PTG Reamers and Cutting Tools are designed to work with petroleum-based lubricant. Water-based lubricant can give acceptable results, however the life of the tool will be reduced. For best results use petroleum-based lubricant.
