Solid Heard Nose Bar
Guide bar is one of the most important elements for the better cutting performance of the Chain saws and is required to guide the saw chain efficiently with lower frictions.
Guide bar and the sprocket have to transform the power of the engine to the cutting force with smallest loss of the power.
And it also has to be endurable under the harsh operating conditions without deforming.
Diatop's Guide bar which can be used under many different kind of conditions and usages can be categorized as Hard-nose bar, Replaceable sprocket nose bar and laminated sprocket nose bar.

Solid hard nose bar (Hard tip) ・・・ The bar is made of solid single plated special steel. Special hardened carbide (Stellite) is welded on the tip of the bar. It is suitable for hard usage such as cutting the hard woods.

Replaceable sprocket nose bar (Star tip) ・・・ The bar is made of solid single plated special steel. Replaceable tip with sprocket is installed on the bar. The sprocket guides the saw chain smoothly and minimize the friction between bar and chain.

Laminated bar with sprocket tip ・・・ Body of the bar is made of laminated 3 steel plates. The sprocket is installed on the tip of the bar.
Solid Hard Nose Bar
data structure
Type
Standard
Solid single plate guide bar for the professional users.
The finest alloy steel SKS-51is used for the base material and it's tracking groove is curved by special tool,The special hardened carbide (Stellite) is carefully welded by skilled workers on the tip of the bar.
Light weight
Light weight guide bar with special hard resin implanted in the bar.
This structure enables 16-22% reduction of the weight without sacrificing the stiffness.
Standard for carving
Solid single plate guide bar for the professional users.
The finest alloy steel SKS-51is used for the base material and it's tracking groove is curved by special tool,The special hardened carbide (Stellite) is carefully welded one by one by skilled workers on the tip of the bar.
Light weight for carving
Light weight type bar with special hard resin implanted in the bars.
This structure enables 16-22% reduction of the weight without sacrificing the stiffness.
Features
・There are no sprockets on the tip of the bar but the special hardened carbide (Stellite) is welded.
Therefore,
- Less chance of failures. (Less down times during work)
- Can be repaired even if it is bent a little by stuck in the wood.
- Can be stuck straight into wood at cutting.
- Chain does not come out the rail easily even if the tension comes loose.
- No necessary to refill the grease. (Easy to maintain)

・Due to single solid plate structure, rigidity of the body is very high.

・Engine RPM is 10% lower than sprocket nose bar due to heavier friction between side link of the chain and bar on the tip portion.
