Head changeable reamer

High precision and productivity solution for finishing hole operations

Applications & Features

Applications

Drilling

Features

1. High precision reamer heads for applications of H7 hole-tolerance range

2. Allows applications of higher cutting speeds and feed rates over solid carbide or brazed reamers, ensuring high productivity

3. 2 types of reamer heads are available depending on the hole types

Inserts & Grades

Inserts

HRM-BL (ø10 – ø32 mm)

  • Reaming heads with left hand flute for through holes

HRM-AS (ø10 – ø32 mm)

  • Reaming heads with straight flute for blind holes
Grades

AH725

  • P15 – P30 / M15 – M30 / K25 – K30 / S15 – S25
  • Good balance between wear and chipping resistance
  • Suitable for machining steel and stainless steel under general cutting conditions
