The beer is the brainchild of EPS Services & Tooling, whose Wiveliscombe base in Somerset is near Cotleigh Brewery, which is producing the beer.
Every bottle of Bandsaw Beer sold will generate 20p for the TTBS.
"We were looking for a way to celebrate our 30th anniversary as a business and working with our local brewer, who is our next-door neighbour, seemed a very good idea," said EPS managing director Nick Palmer.
"It is also a fun way to raise funds for the TTBS, which has been doing great work for more than 100 years helping people in our industry who need support."
Cotleigh Brewery has been producing award-winning beers in the West Country for nearly 35 years.
The 500ml bottle Bandsaw Beer (a 4.2% golden beer) is available online at www.cotleighbrewery.com or telephone 01984 624086. A 30-bottle case costs £69 or 15 bottles £39.90. Smaller gift packs are also available.
