There is almost nothing more frustrating when installing fitted hardware (such as hinges) than having your pilot hole accidentally run off center. The screw itself then tends to be drawn off center, spoiling the perfection you are striving for.
With their conical shaped guide and spring loaded inside drill bit, these Vix-style pro bits have a 1/4" hex shank so they will snap in and out of modern drivers, as well as fit any standard chuck. Replacement drills are available. Made in Taiwan.
