Problem

Bad hole quality Tool wear

Bad surface quality Hole too large Hole too small Tapered hole Non-circular hole Reamer jams Reamer breaks

≈ ≈ ≈ ≈ Causes and corrective measures
Radial run-out error of reamer
≈ ≈ ≈ ≈ Radial run-out error adapter/tool holder

≈ ≈ ≈ ≈ Radial run-out error spindle

≈ ≈ Use high viscosity coolant or cutting oil

≈ Coolant too viscous

≈ ≈ ≈ ≈ Check tool dimensions

≈ ≈ ≈ ≈ Incorrect initial cut

≈ ≈ ≈ Radial land too wide
≈ ≈ Reamer is dull

≈ Ductile material

≈ ≈ ≈ ≈ Insufficient machining allowance

≈ ≈ Pilot hole and reamer axis are not aligned

≈ ≈ Use a floating tool holder
Solid carbide tools / Technical information
≈ ≈ Material tends to jam; use spiral reamer

≈ ≈ Provide with coating
