This chamfering tool features a removable 28 degree carbide cutter mounted in our large, comfortable Sinclair handle. Intended to prepare cases for VLD or boat tail bullets, but works fine for flat base bullets. Also works great on lead bullets - will not shave the base. When prepping large volumes of cases we use the power adapter in the Sinclair Power Center or with a power screwdriver. Will work on 14 caliber thru 45 caliber cases. Mfg: Sinclair International
