Exciting News! We are in the process of completely reworking the headstock slotting and drilling jig to make it bigger, faster, better! 

What you can expect:

  • Compact tool design assists with two challenging tasks – headstock tuner hole drilling and slotting
  • Setup is quick and flexible as tuner hole drill blocks and slot templates can be changed out to match the task
  • Tuner drilling method is designed for a drill press for stable, accurate, and perpendicular tuner holes 
  • Standard 35mm tuner hole spacing is supported - 6mm, 6mm w/bushing, and 10mm
  • Each tuner hole drill block has two preset center height values and can easily be adjusted with precise shims
  • Acrylic slot template dimensions are taken directly from LMI plans and are pin registered for an exact match
  • Slot wall thickness can also be adjusted by referencing an engraved positioning scale on each template
  • Four toggle clamps providing secure, quick clamping of headstock for both operations
  • Machined from Richlite, a very rigid, dense, stable composite product – 100% recycled material

For a short time, we will have the steel string complete drill jig available at a discounted price - 15% off of the original price of $216.25. We will no longer offer the classical version of the original version. Components will be available until stock runs out at which point they will be discontinued. 

LMI developed the Headstock Slotting & Drilling Jig to easily rout consistent slots in the heads of classical guitars or vintage/parlor style steel string guitars. It is CNC machined of aluminum for accuracy. This tool also has a drill guide to accurately drill the 70mm-spaced tuning machine holes. The peghead of your guitar is securely held in place for the routing of the slots by three large thumbscrew clamping bolts.

ClassicalBarHSSJCandTwistDrillHSSJ0131DRILL BITS

Either a bit with a flush bearing or a router base with a guide bushing can be used to machine the slot. We offer a ¼" down cut, spiral bit – CA250DL – for use with a guide bushing set up. Its down shear design greatly reduces tearout for a crisp, clean cut: ¼ shaft, 1" cutting length, 2½" overall length.


The tool is designed for routing and drilling on one side of the head at a time and this work is accomplished quickly and accurately. The tool can be paid for with the time saved on just a couple of jobs. Use our HSSJ1332 13/32" twist drill bit to drill the roller holes if you purchase the classical version or the HSSJDB 6mm aircraft (extra long) drill bit if you purchase the steel string version.

Use our CA250UDL combination carbide upcut/downcut bit for a clean finish on either face of your headstock. It's a little more expensive, but well worth it. We use this bit regularly in our shop. It has a 1/4" 2-flute upcut for 3/16" of the bit, then transitions to a 2-flute downcut for the remaining 9/16" of the cutting length. Overall length 2 1/2", Total LOC: .75".
