Improved and smoother than ever! Big improvements in smoothness and efficiency make this exclusive StewMac tool the ideal fret slotting solution for small shops.

Our R&D luthiers have added ball-bearing guides that make sawing impressively easier and a lot faster. No more binding or jamming: cutting fret slots is a pleasure instead of a chore!

SAVE when you order the miter box with our Fret Slotting Saw or Japanese Fret Saw.

"You won't believe how smoothly our improved fret slotting system works!"
—Don MacRostie, StewMac R&D

The ball-bearing guides hold your fret saw perpendicular to the fingerboard, and can be adjusted to match the blade precisely. You can quickly slot any board up to 3" (76.2mm) wide, with adjustable depth of cut for any fretwire. You always have an unobstructed view of your work, too—a feature you'll appreciate. Made of rugged aluminum and 12" (304.8mm) long, our miter box has convenient mounting holes for firm attachment to your workbench.

Note: Since the Miter Box only accommodates fingerboards up to 1/2" thick, it will not work for traditional Fender style one-piece necks, or one-piece cigar box guitar necks.

Saw precise fret scales without measuring. A special indexing pin in the side of the miter box is for use with our Dual Fret Scale Templates. They enable fast, easy and accurate fret slotting for common scales. No guesswork, no tedious measuring—a tremendous time-saver!

This is a great tool. Set it up proper, fool!

By Hosner Guitars from Science Hill, KY

My shop is really small and on a tight budget. So every tool comes with a lot of consideration and review.

I screwed mine to a 3/4" thick piece of hardwood so it could be held with my sturdy vice. This allows me to easily use C-clamps to hold the fingerboard and fret template in place while I saw. This eliminates the "guide woddle" that is reported by previous reviews.

When setting up the roller guides, use scrap material or the section of the board that is getting cut off, to set your depth.

When the saw makes the metal to metal sound, your cut is done. Check it, to be sure, then move to the next.

A work in progress

This is a decent product and was a huge improvement over slotting frets by hand as I had been doing. However, after using it for 6 or 7 guitars I now have a number of suggestions and critiques.

There is too much wobble with the templates. I am constantly stuffing pieces of paper and feeler gauges between the miter box walls and scale length templates for a snug fit. Accuracy cannot be too high when it wobbles around like that. The box needs to be more appropriately and accurately machined or some type of tighteners must be added that will hug the template snugly in place.

The way that the fret saw rides against the edge of the bearings is odd. I constantly see little brass slivers being shaved off of the fret saw on the bearing edge. It seems like a harsh metal on metal contact even though the bearings are rolling. I'm not sure what the solution to this is, but it seems like a mildly flawed design.

In order to adjust the cutting depth you must loosen a total of 8 allen bolts. Again, not sure what the solution is to this but it eats up a good chunk of time to adjust.

This is a great box and does a fine job, but it could be so much better. For one, there should be height markers on the saw bearings so that you can easily match both sides to the same height. The threading on the height adjustment screws should be much finer.

"How To" for Cigar Box Guitar or one piece neck

By Michael A. from Modesto, CA

Aftern whining that this Miter Box wouldn't work on my Cigar Box Guitar builds ... I came up with a work around that is perfect. As the brass top part of the saw is what glides on the mitre guides ... just get yourself a 14" nylon cable ties and glue them right underneath the brass part of the saw. Perfect thickness with a smoothe edge. It's fantastic and works great. Now you have some working area to adjust the depth. Add a couple 1/4" thick x approx 3/4" wide guide pieces ... and your CBG neck will snap right into place in the middle and it works like a dream. StewMac: You can either post this or just eliminate the post I left whining about it. I love it. -M-

Don't know what I'd do without this. I've been using it to fret my cigar box guitars and for my acoustic restorations. My frets are perfect using the box.

Good but still needs finishing

By Andrew Maz from Austria
(Customer's Reviews) Sunday, August 11, 2013

I have just started using the miter box with the dual fret templates. It basically works ok but there is a fair amount of wobble with the template when cutting as the template is fairly loose in the box. I managed to fix this by grinding down the box base till the wobble was minimized. Maybe stewmac could make the base fit the templates more snugly or make the templates a touch bigger or put some grub screws in the box sides to adjust the fit of the template. No big deal really, just took a while to grind the base accurately. For the price it should work straight out of the box. cheers
