StewMac Ponceuse pour sillets de tête et de chevalet 2026

Never used and still in un-opened box!

Perfectly square, flat bottoms in seconds
For solid contact, good tone, and proper structural integrity, the bottom of a nut or saddle must be squared up. This "vise on wheels" is the fastest, surest way to do this.

It's a common problem in guitar work: how to keep nuts and saddles perfectly vertical while sanding for a truly flat, square bottom? And why does that matter? Because even a slight tilt or uneven surface can prevent full contact between the underside of the saddle or nut and the instrument. That loss of contact will cause a noticeable loss in tone—reduced sustain, less clarity, and inconsistent performance. This is even more pronounced if you use an under saddle pickup.

Sanding these parts by hand is tougher than you might imagine. It only takes a small amount of uneven pressure to throw things off. This tool makes consistently perfect results surprisingly easy. Just clamp your nut or saddle in place, set your depth, and roll it across sandpaper on a flat surface. It keeps everything square automatically, so you get a clean, accurate result every time.

No second guessing, no do-overs.

Tech Tip: We recommend using Stikit Abrasive on surface that is dead flat, hard and smooth for best results. Like the tool table on a table saw, jointer, belt sander etc. 

The new and improved version of features a red anodized aluminum body built for a lifetime of use in your shop. A semi-transparent side makes it easy to align your nut or saddle before sanding, and a built-in reference scale shows exactly how much material you're removing with each turn of the adjustment knobs.

"This takes the guesswork out of squaring up for a perfect fit and getting the exact height on your nut and saddle. Easier to control, and precise results every time." — Gene Imbody, StewMac Guitar Tech

Each full turn of the dial results in the removal of .040" (approx. 1mm) from the bottom of your material. Small adjustments allow you to zero in on the ideal height of your nut or saddle on both ends while keeping the square. Get the perfect height and fit every time!

Holding small parts by hand to remove material accurately is difficult, not only does the Nut + Saddle Sander allow you to do this work with high precision, it acts as a handle to stabilize and control the part and make it easier to work with. No more bad angles or gaps, no more over-sanding and scraped material, and no more sanding your fingertips trying to get it right!
