Chainsaw Bars Buyer’s Guide

Chainsaw Type

Several types of chainsaws can only use specific types of chainsaw guides. For instance, a chainsaw bar made by Husqvarna and Stihl can only be used with their own line of chainsaws.

Nonetheless, there are some notable outliers. It’s possible to get chainsaw bars that are with any model of chainsaw, thanks to their universal design.

Keep in mind that large guides complement high-powered chainsaw motors in any case. A powerful engine will be able to bear the load of the bars and drive the chainsaw.

Bar Type

Solid Bar (With and Without Replacement Tip)

Solid bars provide the most robust form of woodworking hardware available. Thus, they are preferable for working with hardwood and other hard materials. 

The inner and outer tip decreases the load and renders them into a high-performance roller bearing.

The lack of laminations and the use of a solid body in the construction of a chainsaw bar lends them resilience against wear and tear, deformation, and cracking.

Laminated Bar

Lightweight applications, like gardening or yard work, are better suited to laminated bars. Cost-effectiveness aside, they can’t be beaten, making them ideal for homeowners.

In addition to being excellent for cutting hardwood, they are also well-suited for slicing softwood and other types of wood. 

They are more adaptable and may feature nose wheels that reduce backlash and improves safety.

Carving Bar

The smallest and lightest guides are used for carving. These are the most precise tools available and used in carving. Heavy-duty work is beyond their capabilities. These can be used with most chainsaws designed for carving.

Size and Weight

You’ll be able to narrow down your selections and make a more informed decision if you take the size and weight into consideration.

The manufacturer’s website should provide information on the lengths compatible with the tool. Length is the primary factor in determining the weight, while the material also plays a role. 

The lighter and medium-weight bars are better suited for light-duty applications such as yard upkeep and infrequent professional use. In comparison, the heavier bars are better suited for more demanding tasks.

Material Quality

These days, metals like steel, aluminum, and chrome-moly (a combination of chromium and molybdenum) are typically used to make chains saw bars. [1]

Aluminum bars are easier on the body and better for beginners or less demanding exercises.

Regarding tensile strength, chrome-moly bars are superior to their stainless steel counterparts, making them ideal for industrial applications.

Steel is a versatile material that bridges the gap between the two.

Performance

Most guide bar faults may be traced back to improper chain tension, a lack of lubrication, or accidents/irregular working habits; thus, it’s essential to watch for these. 

Even if you have the best bar, but it’s not tensioned correctly, it may wear unevenly and break.

Safety

Working with a chainsaw is risky since it involves using a motorized tool. 

To cut down on kickback and vibration, your chainsaw’s bar should be designed specifically for that purpose.

Kickback from a chain saw can send the cutting edge in the opposite direction of the cut, potentially toward you instead of the target. If you want a new bar with a little kickback, look for the ANSI mark of approval.

Using a chainsaw for extended periods can cause hand and arm fatigue and pain. However, opting for a chainsaw with a bar that features minimal vibrations or incorporates vibration control technology can significantly lessen or even eliminate these discomforts. 

This consideration is particularly important for those who use chainsaws frequently or for extended periods.

Price

The price is also a significant consideration when buying the best chainsaw bars.

Longer, solid bars always cost more because they’re designed for industrial use. They’re a better investment for business owners and professionals because they hold up under heavy use.

If you’re a homeowner who doesn’t plan on cutting hardwood but does need a bar for yard work, I’d recommend opting for a laminated version so you can save money.

When Should You Replace Your Chainsaw’s Guide Bars?

Any chainsaw bar, no matter how well you maintain it, will eventually break from regular use. When that happens, it not only harms the engine and puts you in danger, but it also reduces the cutting efficiency.

The following will help you determine if the chainsaw bar requires a replacement:

How to Choose an Aftermarket Chainsaw Bar

Step #1: Determine if Your Bar Needs Replacement

Bars on chainsaws eventually dull and break. You can take all the precautions the manufacturer recommends (including oiling periodically), but ultimately, it will break. Learn the signs that your chainsaw bar needs replacing.

Step #2: Identify the Right Bar Size

Not all bars can be used with all chainsaws. Certain guide bars and chainsaws aren’t compatible with others, although they’re generally interchangeable. Don’t buy a bar that won’t even fit your saw without first reading these guidelines.

As a general rule, bars from different manufacturers won’t work together. Everyone has their standards, and it’s a sad reality that a company can’t turn a profit by guaranteeing that their competitors’ replacement parts are widely available.

FAQ

What is the most common bar length?

The standard range of 18-20 inches is the most sought-after. These bars have a wide range of uses because of their versatility. They are compatible with a wide range of chainsaw types and brands.

Who manufactures Stihl chainsaw bars?

Stihl also manufactures a comprehensive selection of replacement bars. However, Stihl chainsaw bars are also manufactured by several other companies. In the preceding section above, I listed these some of these products’ manufacturers.
