BB2055 PRO Spiral Flute Carbide Reamer with Internal Coolant
The BB2055 PRO internal-coolant reamer is designed for precision CNC hole finishing from 4 to 12 mm. Internal coolant delivers cutting fluid directly toward the cutting zone, helping improve chip evacuation, temperature control and process stability in demanding reaming applications.
Key Features
Internal coolant delivery to the cutting zone
BB2055 coated carbide series for steel and general metal machining
Spiral flute geometry for controlled chip flow
Solid carbide construction for rigidity and wear resistance
Suitable for precision CNC reaming
Why Internal Coolant?
Compared with external coolant, internal coolant can provide more consistent fluid delivery when the cutting zone is difficult to reach, especially in deeper holes or enclosed machining conditions.
Application Notes
Use only on a prepared hole. Machine coolant capability, pressure, reaming allowance, speed and feed should be selected for the actual workpiece and setup.
