Product Details

Fein Starlock Plus Teak Blades are the fastest, safest way to remove old caulking, adhesive or sealant from between your teak deck boards without damage to the wood.

The end of the blade is shaped to scoop out the old caulking, leaving enough room to re-apply new caulking.

To prevent damage to your decking, select a blade that is slightly smaller than the caulk line you want to remove.

Also works to remove caulking in difficult areas such as curves, cleats, and gunwales.

Sold one (1) blade per pack.

Starlock Plus blades and accessories fit OMTs with the Starlock Plus or Starlock Max mounting system directly, including most Fein and some Bosch OMTs; others will require an adapter. Check for compatibility with your OMT manufacturer.

I would buy and use again.
By Crazy guy from Westport CT

Verified Purchase

It requires a steady hand and good eye sight. It will cut the teak just as easy as the old grout.

Bottom Line Yes, I would recommend to a friend

This tool is great for cutting out old culk
By Timika from Grosse Pointe Woods, MI

Verified Purchase

The caulk channels in 1989 my boat are a 1/4" wide. I first tried a utility knife and scrapper. It took way too much time and energy. Then I tried a router. That was way too hard too control. So I bought the Fein 1/4" cutter and found it fit too tight in the channel as it would drift off and start cutting into the teak :-( So then I got the 3mm cutter. I go down one side then down the other side of the channel. Takes longer but is much easier to control. Also the bottom of the cutter has a rounded bottom so you will have to scrap the caulk out of the bottom corners with a caulk scraper.

Bottom Line Yes, I would recommend to a friend

clean and sharp
By uncle lester from Washington DC

Verified Purchase

Great blade. Stays sharp a very long time. Used it for teak seam caulk removal but also good for cutting coves lines in hull planking. Wish they also made a 60° "V" blade and a 2 mm blade.

Bottom Line Yes, I would recommend to a friend

Excellent Blade!
By D Summers from Huntington Beach, CA

Excellent Blade! I used it to remove the caulk from the entire deck on my 42' Grand Banks. Big Job and it held up. It works on different oscillating tools. Be sure to choose the correct blade width...too small and you will have to pass twice on groove to fully remove caulk.

Bottom Line Yes, I would recommend to a friend

Fein multimaster teak blades
By Yacht Thirdreef from Brunswick ME

Just purchased a 4mm blade and used it to remove seam compound on my 36' Grand Banks. It was easy to use, but as I was only repairing a few seams, making the joins to the existing seam compound was a bit tricky. Complete reseaming of the whole deck would be a long task.

Bottom Line Yes, I would recommend to a friend
