The function of tang is to fit in the chuck.
55 to 60 Degrees
obtuse angle
That's a reflex angle. 0 to <90 Acute angle 90 Right angle >90 to <180 Obtuse angle 180 Straight angle >180 to <360 Reflex angle 360 called Full circle
just an angle, like any other angle.
Type your answer here... 118 DEGREE
118
A twist drill is a drill that has deep helical grooves from the point going up the shank and is used for medal cutting.
One item often overlooked in countersinking, is that it should be done with a countersink, not with a twist drill. This is because the angle of a twist drill is too shallow to match the angle on the head of a countersink screw.Of course, counter sink screws are made in both slottedand Phillips head forms.Countersink screws are usually used for cosmetic reasons, not for engineering strength.
A Twist Drill, could be used on a number of machines, normally a Drill Press, but also on either a Lathe or Milling machine. for certain applications.
In wood work, a twist drill would be used for making small holes where an ordinary wood drill (auger) would probably split the wood.
A standard drill bit.
Low angle makes it three drill lock system.
The parts of a twist drill include the shank, neck, flutes, land, body clearance, and cutting edge. The cutting edge is the point of the drill bit and does the actual cutting.
You sharpen the top, follow same clearance angle, you should not sharpen the face(flute) this can cause the od of the drill too shrink, drills are tapered in length and twist drills have a very small radial land unlike a reg drill. If you take a lot of stock off you will have to resplit the chisel point back to center. If you resplit, hold the drill at a 30deg angle so it cuts faster at center.
i dont know tbh
