Saw Chains

STIHL offers a variety of cutter types and saw chain configurations to meet almost any cutting requirement.

Classic (RSK) Rapid Micro™ (RM) Rapid Super (RS) Rapid Duro (RD) carbide chain) Picco Micro 1
Classic (RSK)
Heavy-duty, fast-cutting chain for use by those with extraordinary cutting needs and specialized training in dealing with kickback situations.

This chain is particularly suitable for felling and bucking big timber with guide bars over 20".

Rapid Micro™ 2 (RM2)
RM2 has triple humped tie strap and lower kickback tendencies. It meets ANSI B175.1.

Ideal for use on farms, in forests and on construction sites. Cutter shape reduces friction, allowing for a higher cutting speed with greater efficiency in any type of wood. Good, stay-sharp characteristics.

Rapid Micro™ (RM) is also available but has higher kickback tendencies.

Rapid Super (RS)
- heavy-duty, fast-cutting chain for use by those with extraordinary cutting needs and specialized training in dealing with kickback situations.

Square cornered cutter shape provides minimum chain friction for an extremely smooth, clean cut in hard and frozen wood. Best suited for high powered chain saws. Also available in "L" version (square ground) and in semi-skip or full-skip versions.

Rapid Duro Special (RDS) carbide chain
- the special chain for the toughest conditions.

Offers increased durability and efficiency with superb stay-sharp characteristics in dirty treated wood. Specially designed to meet demanding cutting needs of the professional.

Under the toughest cutting conditions, the Rapid Duro still achieves a service life that is roughly ten times longer than conventional saw chain, with virtually constant cutting performance.

 

The Picco Micro™ 1 with triple-humped tie straps has been specially developed for use on small chain saws. Smooth running with low kickback tendencies.

Picco Micro™ Narrow is Stihl's first-ever narrow kerf chain... .21" (5.4mm) vs. .25" (6.4mm) for the Picco-Micro™. Used with the new Picco Mini 12" or 14" guide bars. Produces less vibration. Meets ANSI B175.1.

 

Guide Bars

Heavy-duty Stihl guide bars range from 12" to 47" in length and are equipped with Stihl's exclusive Ematic™ lubrication system.

Stihl guide bars are available in two basic versions:
Rollomatic Ematic™ bars | Duromatic Ematic™ bars

Stihl Rollomatic Ematic™ Super bars have a replaceable sprocket nose at the end of the bar which guides the saw chain from the top of the bar to the bottom, minimizing power losses due to friction. They are available with various size sprocket noses. All have induction-hardened rails for long life.

Bars with a relatively small radius reduce kickback and are recommended for amateur and occasional users. They are labeled with a green dot. Those with larger radius are designed for professional users with extraordinary needs, as they permit a higher plunge-cutting performance and longer service life. These are labeled with a yellow dot.

STIHL Rollomatic bars® are further subdivided into four groups:

    STIHL Rollomatic® E Standard STIHL Rollomatic® E Light
    STIHL Rollomatic® Mini STIHL Rollomatic® E Super

     

state-of-the-art laser technology Solid STIHL Ematic™ bars are cut to exactly the right contour with state-of-the-art laser technology.

standard sprocket Concealed inside the bar nose, the sprocket on the STIHL Rollomatic® E-Standard is securely protected against corrosive and abrasive dirt. Never needs additional lubrication.
