Question

what type of wire is best used with v-knurled drive rolls?

only aluminum
all wires
only hard wires
metal cored or flux cored wires

Explanation:

Identify drive roll characteristics

Using the Drive Roll Types and V-Knurled Drive Rolls knowledge points

V-knurled drive rolls feature tiny teeth (serrations) inside the V-groove designed to grip softer, hollow, or tubular wires without crushing them.

Match wire type to roll design

Using the V-Knurled Drive Rolls knowledge point

Tubular wires, such as metal-cored or flux-cored wires, require the extra gripping traction of knurled teeth because high tension on smooth rolls would flatten or deform the hollow wire structure.

Answer:

• Only aluminum
• All wires
• Only hard wires
• Metal cored or flux cored wires (Correct answer)
