How to select the correct OSG Chucking Reamer for a job?

To select the correct OSG chucking reamer, match the reamer diameter to the required finished hole size, typically leaving 0.005–0.015 in for reaming allowance. Choose straight-flute for general-purpose through holes or spiral-flute for blind holes. Solid carbide is ideal for harder materials. Always verify shank size matches your tool holder.
