Professional 5.01-5.5mm diameter solid carbide reamer with tool lengths ranging from 50-150mm, designed for precision hole processing in various materials including copper, cast iron, carbon steel, and mold steel.

• Before using the tool, measure the tool runout. If accuracy exceeds 0.01mm, correct before cutting.
• Keep tool extension from chuck as short as possible. For longer extensions, reduce speed, feed rate, or cutting amount.
• During cutting, if abnormal vibration or sound occurs, reduce speed and cutting amount until situation improves.
• For steel cooling, spray and jet cooling are preferred to improve milling cutter performance.
