To improve my knowledge.. These are not homework questions :)
1. How does 'Trepanning' work and where is it used in the manufacturing industry?
2. What is the need for a 'Lip Relief Angle' in drills?
3. If 15-20 deg helix angle drills are called 'low helix angle' and 35-40 deg are called high, then what about 20-35 deg drills, are these classified as well?
4. What is the 'web size' of a drill?
5. Carbide drills are coated with Titanium Nitride (TiN). is there a particular reason for this?
6. In brazed carbide tipped drills, Tungsten carbide inserts are brazed onto the steel body of a drill. why this particular material?
7. Please explain the 'True Rake Angle' of a boring operation tool. HOW is it a function of side, back rake and lead angle? Also Id be grateful to find a diagram of these?
