Precision Hinge Drilling

Century's 37004 self-centering drill guide creates accurately centered holes for hinges, handles and drawer slides. A replaceable high-speed steel bit handles wood, metal and plastic with equal ease. The 1/4" hex shank locks securely into standard drill chucks and quick-change adapters. Woodworkers and cabinet makers gain repeatable alignment without layout guesswork.

5/64 Inch Bit Diameter

The fixed 5/64" drill bit determines the exact pilot-hole size for your hardware screws. If your hinges or slides require a different pilot diameter this guide cannot be swapped to match. Verify the fastener specification before purchasing to avoid misfit holes.

Replaceable Bit Extends Life

When the high-speed steel tip dulls you can replace only the bit instead of the entire guide. This keeps the self-centering mechanism in service longer and reduces cost per hole drilled. No additional accessories or software are included with the tool.

Questions about this item

How does the 5/64 in bit size translate to actual hinge installation accuracy?

The 5/64 in bit drills pilot holes that match standard hinge screw sizes, while the self-centering guide ensures each hole aligns perfectly with the hinge leaf holes.

What does the 1/4 in hex shank allow me to connect to?

The 1/4 in hex shank fits directly into any standard drill chuck or quick-change adapter, so you can use it with corded or cordless drills without extra accessories.

What clearance do I need around the workpiece for the guide body to operate?

The compact guide body sits flush against the hinge leaf, requiring only enough side room for the drill itself — no special jig or oversized workspace is necessary.
