Harbor Freight has a new Hercules beam cutting attachment that turns your 7-1/4″ standard circular saw into a beam cutter.
They advertise that the new beam cutter can cut beams up to 12″ thick in a single pass, and that it can be used to cut beams, posts, rafters, stair stringers, railroad ties, and logs.
Regarding tool compatibility, the “chainsaw bar and chain mounts securely to most 7-1/4″ circular saws.” Harbor Freight also says it can “securely mount to both conventional and worm drive saws.
The Hercules beam cutter attachment features a low-profile anti-kickback chain, guide bar the entire length of the chain, and automatic oiling system.
Harbor Freight encourages shoppers to compare their new Hercules chainsaw attachment with the Prazi beam cutter attachment, which is currently priced at $169 at Amazon.
There are other attachments from generic no-name brands that are less expensive than the Prazi, but I haven’t seen any as low as the $60 Harbor Freight is charging for the Hercules.
