Which of the following statements about an 8-point saw is not true?

|
an 8-point saw makes a finer cut than a 12-point saw |
|
an 8-point saw makes a rougher cut than a 12-point saw |
|
an 8-point saw makes a rougher cut than a 6-point saw |
Saw blades are described by the number of teeth per inch (TPI). The higher the TPI of a saw the finer the cut it will make.
Which of the following saws would you use if you're cutting wood across the grain?
hacksaw |
|
crosscut saw |
|
back saw |
|
ripsaw |
Wood saws are categorized by their teeth shape and the number of teeth per inch (TPI). The higher the TPI of a saw the finer the cut it will make. Crosscut saws utilize knife-shaped teeth that cut across the grain of the wood while rip saws cut with the grain using chisel-shaped teeth that rip the wood cells apart as the cut is made. The kerf (slot) made by by a crosscut saw is much smoother than that made by a rip saw but a rip saw cuts much faster. Coping saws are a type of bow saw used to make detailed often curving cuts using replaceable blades with fine small teeth.
This tool is a(n) __________.
outside micrometer |
|
outside caliper |
|
vernier caliper |
|
inside caliper |
Calipers are similar to micrometers in shape but instead of measuring distances, calipers are used to transfer distances between objects. An outside caliper is used to transfer outside dimensions while an inside caliper is used to transfer inside distances. A vernier caliper is an extremely precise caliper (down to \({1 \over 1000}\) inch) that allows measuring / transferring either inside or outside dimensions.
You are using a hacksaw to cut a Class 8 bolt. What is the most appropriate TPI for your saw blade?
2 TPI |
|
8 TPI |
|
10 TPI |
|
18 TPI |
A Class 8 bolt is made of very hard metal and larger TPI saw blades are most appropriate for very hard metals.
