It consists of steel links held together by rivets, and superficially resembles the bicycle style roller chain, although it is closer in design to a leaf chain. Its key differences are sharp cutting teeth on the outside of the chain loop, and flat drive links on the inside, to retain the chain on the saws bar and allow propulsion by the engine or motor. Saw chains and chainsaws generally are used for cutting wood. This may be for harvesting trees for pulp or timber, for tree surgery, or for processing firewood. Whether for hand held chainsaws, mechanical timber harvesters or chain mortisers, the saw chain has undergone dramatic development since its invention. Modern chains designed for high power, high speed sawing applications will vastly outperform older designs, while allowing a far greater degree of safety and reliability in use. Principles of saw chain operationeditSaw chains operate by being propelled around a guide bar, removing material from the kerf by cutting chips from the side and bottom. In order to operate properly, the depth to which each tooth cuts must be limited to avoid it binding in the wood. Since 1980 our pickup truck tool boxes have been beaten, crashed, and abused by thousands of our customers. We have reengineered, improved, and tested. Scratcher chain, like the teeth on a hand saw, simply uses a multitude of teeth to prevent individual teeth from sinking too far in without undue pressure on the bar. Chipper chain, and all subsequent designs, incorporate a depth gauge also known as a raker1 on each cutter link to limit depth of cut on each tooth. This has two distinct advantages over scratcher chain it enables the use of fewer cutters per unit length of chain, which allows for shorter downtime for sharpening, and produces a more open chain layout, allowing far better clearance of chips and debris from the kerf. Individual depth gauges on each tooth also enable the use of skip chain.

Skip chain also absorbs less power from the motor per unit length of chain than full complement chain, allowing the use of a longer barchain combination on any given motor.

A section of scratcher chain showing the large number of teeth compared to modern chain. Very early chainsaws used tooth configurations very similar to conventional hand saws. These were very simple saw teeth following a wave pattern left, centre, right, centre with no depth gauges as such, relying purely on bar pressure to limit the cutting rate.

They were inefficient and slow in use, and were soon superseded by chipper chain. They required great skill and a lot of time to sharpen in the field leading to extended downtime between sessions. Chipper teethedit. Oregon brand no. Chipper chain invented by Joseph Cox improved dramatically on the performance of scratcher chain. Chipper used a tooth that was curled over the top of the chain, with alternate teeth pointing left and right. Ahead of the tooth was a depth gauge, which allowed for good clearance around the tooth for chip clearing while limiting the depth of cut and preventing grabbing or overloading.

Modern tooth designseditModern Cutting TeetheditModern chains for general use in forestry, tree surgery and firewood cutting come in three basic configurations the full chisel, the semi chisel, and the chipper chain. Full chisel saw chains. The full chisel chain has square cornered teeth, splitting wood fibers easily in the cut for fast, efficient cutting in clean softwood. Chisel chains have a high kick back risk due to missing safety chain elements and are more sensitive against dirt. These chains are available for semi pro also called pro sumer and professional saws. Semi chisel saw chains. The semi chisel chain has teeth with rounded corners formed by a radius between the top and side plates. While slower than full chisel in softwood, it retains an acceptable cutting sharpness longer, making it the preferred choice for dirtier wood, hard or dry wood, frozen wood or stump work, all of which would rapidly degrade full chisel chain. Variation of the semi chisel chain is Chamfer chisel chains made by Oregon. They are similar to semi chisel design but have a small 4. Performance is similar to good semi chisel. Semi chisel chains have a lower kick back risk. These chains are available for consumer, semi pro and professional saws. Low profile chains. Low profile chains are chains with low teeth and safety elements between teeth. These chains are used on consumer saws for non experienced operators. These chains are more insensitive against dirt, but require more frequent sharpening. Chipper chains. The chipper chain is similar to the semi chisel chain. The key differences between are the size of the radius at the working corner. In cross section a chipper tooth looks like a question mark, having a full radius over the whole cutting portion of the tooth, whereas a semi chisel design is more like a number 7 with the top right corner slightly rounded. Chain arrangementseditThere are also different arrangements of teeth on the chain. Full Complement chain. Chain has a left cutter, drive link, right cutter, drive link arrangement and is used for most applications. Skip chain. Has a left cutter, drive link, drive link, right cutter arrangement. It has 13 fewer cutting teeth and is generally used on long bars 2. Fewer teeth require less power to operate. Semi Skip chain. Alternates having one or two drive links between pairs of cutters, for performance in between that of full complement and skip arrangements. The terms used to describe chain arrangements can be confusing. Most modern chains do not have only cutter teeth and drive links. There are tie straps which separate the cutters from each other. Chain specifications and dimensioningeditCutting chain comes in a large number of configurations, but these are reduced to a few key dimensions for replacement or specification purposes. Gauge. The gauge of the chain is the thickness of the drive links, and is dictated by the gauge of the bar on which it is to be run. Usual gauges are. Chain and bar gauge must match a chain that is too large will not fit, one that is too small will fall sideways and cut poorly. Pitch. The pitch of the chain is the average distance between two rivets. As the distance between rivets varies, the pitch can be measured by measuring between three rivets and dividing this distance by two. Typical pitches are 0. The pitch of the chain must match the drive sprocket, and the nose sprocket if fitted. Sprocket and rim can be in one unit or separated. Length. A chain loop must be of an appropriate length in order to run safely. This is described by the number of drive links. This number is determined by the length and type of bar, the sprocket size and the overall configuration of the saw. For replacement purposes, simply count the drive links on the old chain. Life time of a chain. The teeth of a chain come with a certain length. Wear and sharpening cause the teeth to become shorter. End of life is reached when the top of the head is too short.
