Can I ream a hole to correct location drift?

Reaming will follow the existing hole centerline within the reamer's guidance capability. For location correction, the pre-hole must be within ±0.005 inches of target location. Reaming corrects size and finish, not position — use boring for location correction.

What causes a reamed hole to be bell-mouthed?

Bell-mouthing (enlarged entrance) is typically caused by misalignment between the reamer and the pre-hole axis. Use a floating reamer holder to allow self-alignment. Other causes: excessive feed rate at entry, worn guide pads, or reamer overhang beyond 4× diameter.

How many passes should I use for reaming?

A single reaming pass is standard for 90% of applications. Two passes (rough and finish) can improve surface finish by 15–25% but increase cycle time. For tight tolerances under ±0.0002 inches, consider a rough ream leaving 0.002–0.004 inches followed by a finish ream pass. ⚡ Calculated for Carbide-Tooling.com High-Performance Series.
