6-1/2″ Cordless Circular Saw Testing Format
Article
https://www.toolboxbuzz.com/head-to-h...
Our crew tested a total of eight saws in seven key categories in this test. Our 6-1/2″ Cordless Circular Saw Head-2-Head format, was similar to our 7-1/4″ Circular Saw Head-2-Head. Each of the criteria was ranked separately, and the combined test results were utilized to determine the overall Best 6-1/2″ Cordless Circular Saw.

Accuracy / Line of Sight– The saws’ precision and line of sight were compared, as well as their ability to follow a cut line.
Performance [Power / Speed Test]-We looked at cutting speed through 3/4″ plywood as an indicator of saw motor performance.
Features– An overall comparison of features and specifications.
Weight – bare tool weight only
Noise – We measured the tool under no load and at identical cutting load conditions with a decibel meter.
Price– When it comes to deciding which saw is best for a user, price is always a consideration. At the time of writing, we’ve given the current retail cost for each of the saws “as-tested.” We didn’t consider pricing in our total score because we examined a variety of saw grades.
Best Value –This category winner often strikes a chord with most people because it not only performs well in testing but also feels good on the wallet.

Milwaukee Saw Blades – Model 48-40-0622

All circular saws were equipped with task-specific, brand new Milwaukee 6-1/2″ 40 tooth Fine Finish blades, model 48-40-0622, prior to testing. This shifted the focus away from the blades and more towards the tools. By removing an external testing variable, the use of uniform blades throughout the testing helped to maintain uniformity. Milwaukee blades are popular among the crew because they cut extremely well, are priced just right, and are reliable.

Milwaukee circular saw blades provide long life, improved precision, and cooler cuts in wood cutting applications. These blades are made with application-specific Cobalt Infused Tungsten Carbide blades to improve cutting life and keep tip sharpness.
