AUTOVIC Guitar Tuner Drill Jig for Pin-Mount 6-In-Line Machine Heads

In this review the AUTOVIC Guitar Tuner Drill Jig is evaluated for guitarists who need precise, repeatable holes when installing or replacing pin-mount 6-in-line machine heads on Fender-style instruments. The bottom line: it is a simple, well-machined tool that removes guesswork and speeds up installation, making it especially useful for home techs and gigging musicians who value accurate tuner placement without relying on trial-and-error. The review focuses on fitment, build quality, ease of use and what to expect when using it on Stratocaster and Telecaster style headstocks.

Key Features

• Fitment: Works with Fender, Squier, Schaller, Sperzel, Hipshot and Graph-Tech pin-mount tuners so installers can use a single jig across common 6-in-line models.
• High-precision construction: Machined aluminum body and steel drill guides deliver consistent, straight holes that reduce the chance of misaligned tuners.
• Quick-align design: Visual guide holes speed setup and let users center the jig on the headstock without complex measuring tools.
• No power drill required: Includes finger chucks for the supplied bits so you can control drilling by hand for delicate headstocks.
• Complete kit: The package includes the jig, a clamping knob and two different size drill bits, so you have the core items needed for pin-mount installations.

Who It's For

This jig is ideal for hobbyist guitar techs, DIY players and small shop luthiers who work on Fender or Squier Stratocaster and Telecaster headstocks and want consistent tuner alignment without specialized machinery. It suits anyone swapping in pin-mount 6-in-line machine heads who wants to avoid guesswork and wasted time.

It is less relevant for players using screw-mount tuners, multiformat commercial shops that require CNC-level tolerances, or those who prefer using a full drill press; the jig is optimized for pin-mount models and manual drilling control.

Pros & Cons

Pros

• Solid, machined aluminum construction gives stable clamping and reliable alignment during drilling.
• Steel drill guides keep bit travel straight, which is key to clean tuner fitment on delicate headstocks.
• Includes two drill bits with finger chucks so users can control the cut without a power drill and fine-tune hole size.

Cons

• Not compatible with screw-mount tuners, so it is limited to pin-mount applications only.
• Manual drilling can be slower and requires a steady hand compared with using a drill press for very high-volume work.
