Special bits for templates! Extra-long carbide-tipped router bits produce clean, precise body cavities when used with our templates.

The ball-bearing guide matches the cutting diameter, and the long shank allows multiple-pass routing for deep cavities.

The 1/2" diameter bit is recommended for most of your routing chores, and comes with 1 bearing. Use the 3/8" cutter only for routing corners that need the tighter radius, it comes with 2 bearings.

Sold individually or SAVE when you buy the set of both router bits.

Shank diameter: 1/4" (6.35mm)
Cutting height: 1/2" (12.7mm)

A heat-resistant sleeve (not shown) holds the bearing in position. We recommend stacking an extra bearing on the shank for deep cavities, and use the 3/8" bit only for routing corners.

Tip: We recommend that you change the position of stacked bearings on the router bit's shank every time your re-chuck in the bit into your router. This will greatly extend the life of the bearings and reduces the risk of a bearing "blow-out."

Router bits

Love them. They are short enough that you can use your pickup and neck pocket templates without putting something under them.

Binding and purfling.

I used this 3/8 bit in my small router with the Stew Mac pick up templates to flawlessly rout out a 3 pick up cavities on the top of my last guitar build. The small bit's bearing will hold up if you take it really easy. The bearings held for me but next time I will use the 1/2 bit for the rough cuts and the 3/8 bit for the finish cuts.

Best Bits for handeld routing with a template

By Midnight Luthiery from USA

IÆve used these bits for many years and they are simply the best available for cutting guitar cavities with a handheld router and templates. There really isnÆt another short depth of cut top bearing alternative on the market. If you follow these rules the bit should last for many guitars. Rough out your cavities with a Forstner bit on a drill press first. Make conventional cuts moving the spinning bit AGAINST the grain at all times. Rout in small passes when possible half the cutter diameter to ensure cutting against the grain, or even a quarter for the final pass against the perimeter of the template. Likewise 3-4 passes for standard depth neck and pickup cavities. If you need 3/8ö diameter corners do all your routing first with +ö, then recut the corners only with 3/8ö. If you are building more than 2 guitars at a time consider buying multiple bits and rotating them during your operations to reduce over-heating. Do not even think of cutting a neck or body outside perimeter off a template with these in a handheld router. ItÆs the wrong tool for that job and can easily cause damage or injury, use a router table and bottom bearing bits instead.

really good stuff, strong, easy to used it, thank you very much Stewart mc D

A bit disappointed...

These are very nice.... at first. They dull very fast. They are hard to find, like most luthier related tools, anywhere but through a specialty supplier like StewMac. Also, if you buy them get at least 4 or more additional bearings. Make very shallow passes on hardwoods. Let them cool frequently. I wish they made them in carbide.

The first router bits I ever bought were from StewMac and came with the bearings as a set. Upon needing new/different bits, I tried some sets from a major retailer of of tools and household items. The bearings that came with those bits fragged in short order, sometimes causing damage to the work piece. For the trouble of hunting around and/or unknown quality, it's well worth continuing to order these bearings.

Awesome as always!!
