PRODUCT DETAILS

MGR Series Solid Carbide Micro Boring Bars

The MGR Series is a specialized solid carbide micro boring bar designed for internal grooving, relief grooves, ring grooves and seal grooves in small bores.

Featuring a square / narrow radial grooving blade, it delivers precise and clean radial grooves, snap ring grooves and oil grooves with excellent chip evacuation and high rigidity, making it ideal for stable machining in confined internal spaces.

Key Features & Applications:
  • Internal straight grooves, relief grooves, ring grooves and seal grooves

  • Square / narrow radial grooving blade for clean cuts

  • High rigidity minimizes vibration in small-diameter bores

  • Excellent for snap ring grooves, oil grooves and sealing applications

  • Ideal for stainless steel, H13, P20 and general engineering materials
