Black Diamond Saw & Machine Works is a maker of saw-filing machines. They have been in business since 1911. By about 1939 they were making sharpening machines for twist drills. In 1955 they acquired the rights to the "Worcester Drill Grinder" product line that had been developed at Worcester Polytechnic Institute beginning about 1900 and had been manufactured by the Washburn Shops of WPI.

Black Diamond are now the makers of Wright bandsaw guides, originally manufactured by C. E. Wright Co. Black Diamond's phone number is 508-653-4480.

Some Black Diamond bandsaw filing and setting machines have been seen with a patent date corresponding to a 1909 patent granted to Artemas C. Ambler of Natick. He had earlier been co-inventor on machines related to boot- and shoe-making. In 1939, George B. Ambler of Natick was granted a patent for a twist-drill sharpening machine. That patent was assigned to Black Diamond Saw & Machine Works.
