Which type of cutting tool has an expensive cutting material fused to a less expensive material?

• A. Brazed-tipped
• B. Welded-tip
• C. Solid carbide
• D. HSS

Answer: (A)

The idea being tested is pairing a very hard cutting edge with a tougher, cheaper body to balance wear resistance and toughness. In a brazed-tipped tool, an expensive cutting material such as carbide is joined to a less expensive steel body using brazing, which uses a filler metal to bond the pieces without melting them. This lets the tool have a hard, wear-resistant tip where it matters most, while the rest of the tool remains tough and cost-effective. Solid carbide tools are made from carbide all through, which is excellent for hardness but can be more brittle and expensive overall. HSS tools are just steel and don’t use a separate hard edge. Welded-tip tools exist, but brazing is the common method that specifically describes fusing a hard tip to a cheaper substrate.
