🔍 Key Concepts

• How a right-handed cutting tool is normally turned during cutting versus during removal • Why reamers and taps can bind or chip if you apply side pressure or hammering force • Safe practice for withdrawing a cutting tool from a finished hole to avoid damaging the tool or workpiece

💭 Think About

• Think about the normal direction of rotation for a right-handed tool while cutting. When you are done cutting and want to back it out, what rotation prevents further cutting and reduces binding? • Consider what might happen to the cutting edges and the accuracy of the hole if you hit the reamer or rock it side-to-side inside the hole. • When you remove the reamer, should you lift it straight while controlling rotation, or apply force sideways or with impact? Which method best protects both the tool and the finished hole?

✅ Before You Answer

• Identify which choices involve impact or side pressure on the reamer and reconsider those based on safe shop practice. • Check which options rotate the tool in the same direction it cuts versus the opposite direction and think about which direction is used to back a right-handed tool out. • Confirm that the correct method involves controlled rotation and gentle lifting, not forcing, tapping, or wiggling the tool.
