Product Details

New quick-adjust wheel! The world's most popular fret bender, now with a new brass thumbwheel to control the radius. Simpler and faster than ever!

A great idea: Crank a length of fretwire through the FretBender, and it comes out curved and ready to install in a radiused fretboard. Get a perfect bend on enough wire for a whole guitar in just seconds.

Perfectly radiused fretwire, guaranteed
Insert the wire, turn the crank, and out it comes with a constant curvature that you'd never get by bending with pliers. Precisely radiused fretwire makes your fretwork fast, accurate, and professional. StewMac's FretBender is a valuable addition to your busy shop, we guarantee it.

New thumbwheel: the brass adjuster on top is an easy, controllable way to dial in your radius. A great addition to a product that's proven its worth since the 80s when repairman Randy Stockwell's idea inspired this tool!

The FretBender uses precision ball-bearing rollers. The heavy-duty aluminum column can be clamped in a vise, or use the pre-drilled bolt holes to mount it to your workbench.

"Bending every fret by hand takes me about 15 minutes, and I get uneven results. This tool does the job perfectly in less than a minute."
— Dan Erlewine

How it works
Your choice of fretwire will determine where to set the thumbwheel—every wire is different. Run a 6-inch test piece through the FretBender and compare it to your fretboard. Turn the wheel counterclockwise to lower the guide wheel for a tighter radius. When you have the curve you want, lock it in with the knob on top.

Start your test with flat wire, then increase as needed; you can't unbend fretwire that's too tightly curved.

An essential tool for fret jobs. Very well made, easy to use and very durable. A little expensive but worth buying.

I used this tool on my first guitar that i make, and it was great. All the parts are ordered from Stewmac. The guitar was finished 12.01.2014. It's nice to play, but there are things that i can do better on my next guitar. Sorry about my English.

Fantastic tool!

Just perfect - period
Why have I been bending by hand frets for the past 17 years when it can be done in seconds and dead accurate? What a time saver!

Super tool

I looked around the internet before I purchased this tool. I found some cheaper but the quality lacked. This is the best tool for bending fret wire.
