The large gullets of coarse-pitch blades help minimize clogging.
Positive rake teeth have from 5 to 15 deg rake and large gullets to hold the long chips formed on large workpieces.
Tooth geometry, including the rake angle, clearance angle, and gullet depth, is tailored to different applications.
Formerly, gullets were cut by milling, with the broach in the unhardened condition.
After the start button is pushed, the machine cycles automatically until the tooth gullets in all the broaches are machined.
Wheel life depends on width and depth of gullets and, to some extent, on the grindability of the tool steel.
