16.5mm Timberline drill bit is a dedicated bit for boring holes for CompX Timberline Lock cylinder bodies, so installers get a hole sized to match the cylinder design instead of working from guesswork. The 16.5mm diameter drills the proper diameter hole for most Timberline cylinder bodies, which supports a close fit at the cylinder and helps the lock body sit correctly in the panel. The DB-165 identifier ties directly to the Timberline drawer lock system, so it is easy to match this bit to Timberline gang locks and related cylinder bodies in the same system. The drill bit is part of a drawer lock system, so it is aimed at woodworking and cabinetry tasks where Timberline gang locks and cylinder bodies are used together in casework or drawers.
The 16.5mm drill diameter is matched to most Timberline cylinder bodies, so bore sizing is handled by the bit instead of later fitting around the lock body. The 10mm shank diameter connects the bit to chucks or collets sized for that shank, which supports stable rotation during boring. Because the bit is described as 16.5mm drill bit 10mm shank diameter, installers can set up equipment around both the cutting diameter and the drive shank size. The bit is identified with DB-165, tying it to the CompX Timberline Lock drawer lock system and helping shops keep drill tooling aligned with their Timberline lock components.
The drill bit is listed under Locks and Latches and Drawer Lock System, so it is aimed at work where Timberline gang locks and cylinder bodies are mounted into drawers or casework. Because the Web Description states it drills the proper diameter hole for most Timberline cylinder bodies, its role is to create the cylinder bore in panels that will receive Timberline lock cylinders. The Timberline brand reference and CompX Timberline Lock naming place this bit directly in the Timberline product family, so it fits workflows where that specific lock line is standard for projects. The 16.5mm size is tied to those cylinder bodies, giving installers a dedicated bore size for that hardware.
The DB-165 manufacturer part number links the drill bit to the Timberline drawer lock system, which makes it easier to repeat results when matching drill tooling to specified Timberline locks across jobs. The 16.5mm diameter being described as the proper diameter hole for most Timberline cylinder bodies means the bore sizing is defined by the lock manufacturer, which supports repeatable cylinder fits when running multiple panels or drawers. The 10mm shank diameter is called out along with the cutting size, so equipment can be standardized around that shank, reducing set change issues when operators move between machines that accept 10mm shanks. Positioning the bit within the Drawer Lock System class keeps it tied to the same family as gang locks and cylinder bodies, which helps shops maintain a consistent setup for Timberline-based locking layouts over time.
