StewMac Endpin Jack Reamer – 2-Step Precision Tool for 15/32" & 1/2" Jacks – Excellent Condition

For sale is my StewMac Endpin Jack Reamer in excellent condition. This is an outstanding precision luthier tool that I used once to install an endpin jack for a K&K pickup in a vintage guitar without butchering the guitar. This tool made the exact size hole I needed with no wiggle room.

I chose to purchase the tool rather than hire a luthier for this install and it worked out great. DO NOT try to enlarge your endpin jack hole on a nice guitar with a regular drill bit, use a proper endpin jack reamer.

This is the official StewMac 2-step reamer, a favorite among guitar builders and repair technicians.

I’ll mail this in the folded cardboard sleeve pictured in the photos.
