Common Questions▼
Q: What is STIHL part number 3624 005 0072?
A: Part 3624 005 0072 is the STIHL 33RS3 72E, a genuine OEM full-chisel saw chain loop with a 3/8" pitch, .050" gauge, and 72 drive links. It is also known as the STIHL Rapid Super 3 chain and is designed for use on compatible STIHL chainsaw models with approximately 20" guide bars.
Q: What does the 33RS3 72E chain designation mean?
A: In the STIHL chain naming system, "33" refers to the cutter sequence, "RS" stands for Rapid Super (full-chisel cutter style), "3" indicates the chain sequence (every 3rd link has a cutter), and "72" is the number of drive links. The "E" suffix denotes the loop form factor, meaning this part is sold as a pre-assembled closed loop ready to install.
Q: Is the STIHL 33RS3 72E a full chisel or semi chisel chain?
A: The STIHL 33RS3 72E (part 3624 005 0072) is a full-chisel chain. Full-chisel cutters have a 90-degree corner between the top plate and the side plate, which produces faster, more aggressive cuts than semi-chisel cutters. It is best suited for clean wood and professional cutting applications rather than dirty or abrasive conditions.
Q: What bar length does the STIHL 3624 005 0072 chain fit?
A: The STIHL 33RS3 72E chain with 72 drive links is generally compatible with 20" guide bars on STIHL chainsaw models that use a 3/8" pitch and .050" gauge. To confirm the correct fit for your specific saw, check your guide bar's specifications or refer to the STIHL parts lookup tool for your model number.
