The main things you should be looking out for when choosing a circular saw are cutting capacity, cutting depth and bevels. The capacity and depth of your cut with a circular saw is based on the size of the saw’s blade.
How big should my circular saw be?
The most common and useful size for DIYers is 7 and 1/4 inches. Saws this size will cut through material more than 3-inches thick, and they also offer the widest variety of blade choices for cutting substances other than wood.
What are the 3 basic types of circular saw blades?
They are: Rip Blades, Crosscut, Combination and Specialty blades. Ripping saw blades are designed primarily to achieve a smooth, clean and safe cut when ripping wood or cutting in the same direction as the wood grain.
What is the difference between circular saws?
Regular circular saws have an RPM of 6,000 or higher while worm drive saws have an RPM of not more than 4,500. This difference of RPM is however balanced when it comes to torque. Worm drive saws offer more durability and power because they have larger teeth which have a more loading capacity than regular circular saws.
What is a good RPM for a 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 teeth should my saw blade have?
Combination: 10-inch blades with 50 teeth and 12-inch with 60 teeth. Ripping: 10-inch blades with 24-30 teeth and 12-inch blades with 40 or fewer teeth. Crosscutting: 10-inch blades with 60 teeth and 12-inch with 80 teeth.
What size circular saw will cut a 4×4?
Cutting a 4×4 with a Circular Saw – Guide
If you need to cut a 4×4 post, then the ideal tool is a large 12” miter saw. This saw has the blade diameter needed to chop through a 4×4 in a single pass, so if this is an option for you it’s the way to go.
How many watts is the average circular saw?
A circular saw typically runs on around 1,200 watts of electrical power.
Can you cut wood with metal circular saw?
You can use a metal blade to cut wood. A circular saw blade cut metal in a sluggish rotational speed of 25m/s. They are driven by a motor having high power and an A/C vector drive. They are long lasting and non-reusable.
What speed does a saw blade last longer?
For extended blade life and quality of cut, saw blades should run between 10,000 and 18,000 SFPM (surface feet per minute). Never exceed 18,000 SFPM!
What is the speed of a circular saw?
It is clear that in the speed range from 1173 to 1500 rpm, the circular saw would easily be- come unstable and pose a hazard to the people working with it. Critical rotational speed theory of the circular saw has been a subject of many scientific publications.
What is RIM speed?
Rim speed = How fast the rim is traveling… If the circumference, the distance around the disk, is 36 inches and the angular speed is 1000 rpm, then the rim speed is circumference times RPM, here 36 x 1000 or 36,000 inches per minute. That equals 3,000 feet per minute (divide by 12).
How do you measure band saw blade speed?
The formula to determine S.F.P.M. is:
Motor RPM multiplied by the Motor pulley diameter divided by the Driven pulley diameter times the Bandsaw wheel diameter times pi (3.1416) divided by 12 = S.F.P.M.
Why are the wheels of band saws fitted with rubber tires?
A primary advantage of rubber band saw tires is that they stretch in place for a perfect fit and offer versatility — they work with virtually any type of portable or stationary vertical band saws. Some rubber tires can even be cut to fit the width of a non-standard wheel.
What is meant by the feed rate of a saw?
The Feed Rate is defined as the amount of material (in square inches) that a band saw can cut per minute. This number or amount is often referred to as S.I.P.M. (Square Inches Per Minute).
What speed should I run my bandsaw?
A common speed for the bandsaw is about one thousand feet per minute. Wood can effectively be cut at much higher speeds, up to and over five thousand feet per minute, but you should keep it slower because it’s safer.
Why do bandsaws have 2 speeds?
2 Answers. Show activity on this post. The primary reason for speed adjustment on bandsaws is to accommodate different materials (mainly metal). That said, dropping the speed down for some operations can stretch the capabilities of an underpowered machine further.
Why do bandsaws have two speeds?
Quote from the video:
Quote from Youtube video: So your traditional bandsaw. Has one speed you can change the blades to coarser or finer depending on the type of cutting you're doing but really you're just limited to cutting timber.
