Introduction

Boring reamers create accurate, smooth holes in engine components where tight tolerances matter. Proper diameter and flute design help maintain consistent results.

  • Select the correct diameter range for your engine block or head work.
  • Match flute count and material to the workpiece for clean cutting.
  • Check shank size to fit your existing boring bar or holder.

Find the reamer size that matches your engine project.

FAQs

Most reamers handle cast iron, aluminum, and steel. Always match tool material and coating to the workpiece hardness.

Leave 0.1-0.3 mm stock for finishing. Too much stock can cause chatter; too little reduces accuracy.

Coolant or cutting oil reduces heat and improves finish. Use the fluid recommended for your workpiece material.

Hand reaming is possible on soft materials, but machine use gives better concentricity and repeatability on engine parts.

Keep them in individual sleeves or a dedicated rack. Avoid metal-to-metal contact that can chip cutting edges.
