01
Operating Instructions
Adjustment starts one of twin cartridge on ABH/DBH boring head.
Step 1: Unlock clamping screw anti-clockwise (see figure 5).
Step 2: Loosen adjusting screw (See figure 3). Move cartridge to the required position according to the reference line marked on the tool body (see figure 4).
Step 3: Fasten clamping screw properly (see figure 5).
Follow the same steps aforementioned to adjust the other cartridge.

Boring Options
Two boring options available with ABH/DBH rough boring head.
① Balanced cutting: Cartridge A on side A, while cartridge B on side B. For stable cutting with a small stock allowance. (See figure A)
② Stepped cutting: Cartridge A on side B and cartridge B on side A. For cutting with a big stock allowance. (See figure B)
4. Notices Of The User
Make sure the cutting data for the two cartridges are same when stepped cutting is adopted.

Frequently Asked Questions
Q
What is the difference between the ABH and DBH rough boring tool series?
The ABH and DBH series are both twin-cutter rough boring heads designed for efficient material removal. The DBH 6º variant features a 6-degree cutting angle for improved chip evacuation and reduced cutting forces, making it suitable for applications requiring a larger stock allowance or specific insert geometries such as SPMT and SCMT inserts, while the standard ABH/DBH series uses CCMT inserts with a conventional cutting angle.
Q
What boring diameter range does the ABH/DBH rough boring tool cover?
The ABH/DBH rough boring tool series covers a wide boring range from Ø20 mm up to Ø204 mm, with adapter sizes from DCK1 through DCK7 to accommodate different machine spindle interfaces and workpiece requirements.
Q
What is the difference between Cartridge A (DACC/DASP/DASC) and Cartridge B (DBCC/DBSP/DBSC)?
Cartridge A and Cartridge B are the two opposing cartridges in the twin-cutter boring head. In balanced cutting mode, Cartridge A is mounted on side A and Cartridge B on side B for stable cutting with small stock allowance. In stepped cutting mode, the positions are swapped — Cartridge A on side B and Cartridge B on side A — enabling cutting with a larger stock allowance. Both cartridges share identical insert and screw specifications within the same size range.
Q
What adapter interfaces are available for the FM-DBH large diameter rough boring tools?
The FM-DBH large diameter rough boring tools (FMS and FMX series) are compatible with multiple standard adapter interfaces, including HSK-A, BT, SK, BBT, and CAT spindle connections. Extension aluminum bridges and rough boring sliders are also available as accessory components to extend the reach and adjust the boring diameter.
Q
What insert brands are compatible with the FM-DBH large diameter rough boring tool?
The FM-DBH large diameter rough boring tool is compatible with inserts from DEREK, KYOCERA, and SUMITOMO brands. The cartridge specifications S12-R40-CC12 accepts CCMT1204 inserts, while S12-R40-CN16 accepts CNMG1606 inserts, providing flexibility in insert selection based on material and machining requirements.
Q
What are the key features of the FM-DBH large diameter rough boring tool series?
The FM-DBH large diameter rough boring tool series is engineered for high-performance large hole machining. Key features include: 70–90% aluminum construction for reduced weight and vibration, built-in internal coolant supply for effective chip removal and tool life, axial direction adjustment of 0~1.5 mm for precise depth control, and a balanced design rated at G6.3 at 1,000 rpm for smooth high-speed operation.
