What size circular saw will cut a 4×4?
The best way to cut a 4×4 post is by using a 12-inch miter saw, 10-inch radial arm saw, both of which can cut completely through a post in one pass, or a standard circular saw that can make precise cuts in two passes with the help of a simple jig.
What is the best circular saw blade for wood?
The following guide contains the information necessary to choose the best circular saw blade for any task.
Is a brushless circular saw better?
A higher efficiency rating also means a 20-volt battery can dedicate more power to turning the blade, resulting in more torque and higher maximum rpm. The most powerful cordless circular saws, including those capable of turning 7¼-inch blades, use brushless motors.
What are the 2 types of circular saws?
A1: There are two basic types of circular saws: the worm drive saw, which can be identified by its rear-mounted motor, and the sidewinder, so named because its motor is positioned alongside the blade.
Whats a good rpm for circular saw?
But speeds tend to be relative because a 15-amp motor can spin a 7¼-inch blade faster than it can spin a 10¼-inch blade. Generally speaking, when it comes to 7¼-inch saws, speeds between 4,500 and 5,500 RPMs are common and should be adequate for fast, accurate results.
What is good rpm for circular saw?
There is in fact fairly common agreement that for general work, the tooth should be moving somewhere around 130 to 170 feet per second. That may look like a big spread for you, but if you look at the fact that we are dealing with tools that vary from 3,000 RPM to 50,000 RPM, 130 – 170 fps is rather consistent.
How many mph is 3000rpm?
is approximately 6 feet per revolution, or about 850 rev/mile. The “transmission” is approximately an 8 to 1 reduction in rpm, so the motor must turn about 6800 revolutions to go one mile. Thus, at 6800 rpm one is going 1 mile per minute, or 60 mph, approximately.
How shallow can a circular saw cut?
Circular saws turn corners about as well as a freight train, and standard models will cut only about 2 1/2 inches deep. There are ways around the shallow cut—for example, you can flip over a 4×4 and cut from two sides—but the curve limitation has no work-arounds.
