FretBender demo: putting the curve in guitar frets

Dan Erlewine demos the StewMac FretBender. This great idea came from luthier Randy Stockwell in the 1980s, and now it's a must-have tool in guitar shops everywhere.

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.

You can find cheaper ones, but always remember you get what you pay for. Have not seen one to top this bender yet.

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!

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.
