What is Twist Drill bit?
Twist drill bit is used in wood and metals to make clearance holes for bolts and screws, and to make holes for tapping. The most common twist drill bit has a point angle of 118 degrees, acceptable for use in wood, metal, plastic, and most other materials, although it does not perform as well as using the optimum angle for each material. In most materials it does not tend to wander or dig in. Only precision twist drill bits marked HSS twist drill bits are suitable for drilling in metals.
