Twist bits are also available coated with ______________

Twist bits are also available coated with ______________ Correct Answer Titanium Nitride

Twist bits coated with Titanium Nitride are easily identified by the gold like colour. This coating increases the hardness of the bit and adds self lubricating property. The coating is only really effective when metal is being drilled, it has little effect when working with other materials.

A message consisting of 2400 bits is to be passed over the Internet. The message is passed to the transport layer which appends a 150-bit header, followed by the network layer which uses a 120-bit header. Network layer packets are transmitted via two networks, each of which uses a 26-bit header. The destination network only accepts up to 900 bits long. The number of bits, including headers delivered to the destination network, is
