To prevent the formation of long chips, what is ground?

• A. A chip breaker
• B. A broadnose tool
• C. The tool sharpened
• D. The feed increased

Answer: (A)

Chip control is achieved by shaping the tool so the chip breaks as it forms. A chip breaker is a small feature—often a groove, ramp, or step—ground into the tool behind the cutting edge that interrupts the continuous chip and forces it to fracture into shorter pieces. This keeps chips from curling into long, troublesome strands, makes evacuation easier, and reduces the risk of entanglement or damage.

Other options don’t provide that deliberate interruption. A broadnose tool mainly describes the shape of the cutting edge and doesn’t inherently break chips. Simply sharpening the tool doesn’t create a breaking mechanism, and increasing the feed can produce thicker, longer chips rather than shorter ones.
