What is raker tooth?
: an unset sawtooth that cleans out the bottom of a cut.
What is the raker on a saw blade?
The rake or hook angle is the amount of forward or backward lean each tooth has. A hook angle can be thought of as the angle at which the tip enters the material. If the saw tip enters the material at an angle it will be more efficient than if it slaps down flat.
What is a hook tooth saw blade?
As the name suggests, the teeth on hook-tooth blades resemble hooks, raked aggressively forward. They cut quickly, but the sides of the kerf are rougher and there is noticeable tearout along the bottom of the workpiece, where the teeth exit the wood.
What is the best TPI for cutting wood?
TPI is the number of teeth the blade has per inch. If you’re looking to cut wood or other soft materials, you’ll need a blade with a TPI of 6 up to 20. For harder materials like metal, a TPI between 14 up to 36 is more suitable.

What is the difference between hook and Raker bandsaw blades?
Regular blades are ideal for cutting thin materials with a fine finish. Skip tooth blades have widely spaced teeth at a 0 degree rake angle to prevent clogging when cutting soft wood, non-ferrous metals and plastics. Hook tooth blades have a deeper gullet—that is, larger teeth—and a positive 10 degree rake angle.
What is a positive hook blade used for?
A table saw wants a blade with a relatively high positive hook which helps hold the wood down to the table and helps pull the wood through the saw. A radial arm saw or even a miter saw, wants a blade with a neutral or negative hook to keep the saw from wanting to bite into the wood and come out at you.
What saw blade makes the smoothest cut?
crosscut blades
With fewer spaces between the teeth, crosscut blades remove less material, resulting in a smoother cut. It also means it takes these blades longer to move through wood. Crosscut blades are the go-to choice for finish carpentry and other applications that require precision and a smooth finish.
Is more TPI better?
Woodworkers quickly learn that the number of teeth-per-inch (TPI) on the blade has a big impact on the quality of a cut. The general rule of thumb is “the more TPI, the smoother the cut.” The true answer, however, is just a little more complicated than that, as you’ll learn once you understand how saw teeth work.
What speed should a bandsaw run at?
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.

How many band saw teeth should contact the workpiece at once?
For wood and soft materials aim for 3 – 6 teeth in the workpiece. For metals and harder materials aim for 6 – 24 teeth in the workpiece.
How high should the rakers be on a chainsaw?
The raker should be about 0.50. 8 mm lower than the cutter. You sharpen the cutters first.
What is the purpose of rakers on chainsaw?
What do chainsaw rakers do? Chainsaw rakers control how deep the chainsaw tooth cutter penetrates the wood. Essentially what they do is prevent the edge of the tooth from biting too much into the wood. Rakers help determine the height that the teeth cutters will cut into the wood.
How deep should rakers be?
How many TPI does a bandsaw blade need?
A coarse tooth blade (2, 3 TPI) should be used for resawing wood and cutting thicker stock up to 8″. A fine toothed blade (18 to 32 TPI) should be used for thinner metals and plastics under 1/4″. For general cutting of 3/4″ wood 4 TPI will provide a fast cut and 14 TPI will cut slow, but leave a smoother finish.
When should you use a negative hook type of saw blade?
A low or negative hook (less than 5°) produces a smoother, slower cut, and is ideal for hard and brittle materials such as melamine and metal. Negative hook angles also inhibit the blade’s tendency to climb the material being cut, which is why they’re a must for use on miter saws and radial arm saws.
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.
Is more teeth on a saw blade better?
Number of Teeth
Generally, blades with more teeth will provide a smoother, finer cut whereas blades with fewer teeth will provide a rougher cut. The benefit of fewer teeth is faster cutting and a lower price. For most construction work, a 24-tooth general use blade is sufficient.
How long should a circular saw blade last?
They can last between 12 and 120 hours of continuous use, depending on the quality of the blade and material they’re used to cut.
Is 120 TPI better than 60 TPI?
The higher 120 TPI casing is lighter, thinner and will be able to better conform to the shape of the terrain. However, the 60 TPI casing is more resistant to puncture, abrasions and cuts.
