Common questions
Q: Will this 7” x 16T chainsaw tooth blade fit my STIHL FS91R or FS56RCE straight-shaft trimmer?
Yes, this blade is listed as compatible with STIHL FS91R and FS56RCE, along with the other models you noted. Before installing, make sure your unit has the correct blade-capable guard and hardware, and confirm the arbor/mounting setup matches your gearbox output shaft.
Q: Is a 7-inch 16-tooth chainsaw tooth blade a good choice for clearing saplings and heavy brush with a STIHL FS131R?
Yes, a 7” 16T blade is typically used for aggressive cutting in thick weeds, woody brush, and small saplings where string trimmer line struggles. On an FS131R, it should cut efficiently as long as you keep the teeth sharp and avoid striking rocks, fence wire, or dirt, which can damage the cutting edges.
Q: What’s the correct way to install and maintain this blade on a STIHL FS70R or FS111RX?
Install it with the machine off, the shaft locked, and the blade clamped evenly using the proper STIHL mounting hardware and guard for metal blades. Check that the blade spins true before use, then clean off sap and debris after each job and inspect the teeth regularly for dullness, chips, or cracks.
