Common Questions▼
Q: What is STIHL part number 3623 005 0072 and what chainsaw does it fit?
A: STIHL part 3623 005 0072 is an OEM Rapid Super (33RS) full-chisel saw chain with 72 drive links. It is designed for STIHL gas chainsaws running 18 to 20-inch guide bars with a 3/8 in. pitch and 0.050 in. gauge, including models such as the MS 271, MS 291, MS 311, MS 362, and MS 391.
Q: What is the difference between STIHL 33RS-72 and other STIHL chain types?
A: The STIHL 33RS (Rapid Super) chain uses a full-chisel cutter that cuts faster and more aggressively than semi-chisel chains like the 26RM or 33RM. It is best suited for clean wood cutting where maximum speed matters. Semi-chisel chains stay sharp longer in dirty or abrasive conditions but cut more slowly than the 33RS-72.
Q: How do I know if 72 drive links is the right count for my STIHL chainsaw bar?
A: Drive link count is determined by your guide bar's length and pitch. For a 3/8 in. pitch bar, a 72-drive-link chain (part 3623 005 0072) typically fits 18 to 20-inch bars. You can confirm the correct count by checking the label on your existing chain, the marking on your guide bar, or your STIHL chainsaw owner's manual.
Q: Is STIHL 3623 005 0072 a genuine OEM chain or an aftermarket replacement?
A: Part number 3623 005 0072 is a genuine STIHL OEM saw chain manufactured by STIHL to factory specifications. It is not an aftermarket or generic chain. Using genuine OEM STIHL chains ensures proper fit on STIHL guide bars and sprockets and maintains the cutting performance your saw was designed to deliver.
