The clear difference between positive and negative rake angles is that for the positive rake angle,the leading edge of the cutting tool is behind the perpendicular of the material to be cut.While the tool leading edge is ahead or beyond the perpendicular for the negative rake angle.
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.
It is the angle between the cutting edges.It is usually 118 degrees
118 degrees from the axis of the bit is the most common drill bit angle. -There are sharper and more obtuse angles in specialised drill bits.
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.
Wood cutting drill bits are made of steel and are usually 'brad pointed' -this means having a very sharp, narrow point in the middle of the bit's end.
low helix angle drill bits are used for machining hard materials
It is just one of the best drill bits for drilling in the Oil & gas industry. A drill bit is basically the bit on the end of the drill that does the cutting. A premium drill bit is one that is used in really tough applications.
The drill bit's tip is cutting away wood or metal and creating heat because of the friction involved. If you touch the blade of a saw after cutting, you'll notice the same.
A blockage at the leading edge of the bit.

The wedge on a drill is the cutting edges on the end of the drill bit. The sharp edges grab and "wedge into" material to remove it.
Friction. When the drill bit is doing its job, cutting the material causes heat and so does the contact of the flue against the walls of the hole.
