Alésoir en carbure BB (2,0 à 20,0 mm) à cannelure hélicoïdale-BB2055

BB2055 Spiral Flute Solid Carbide Reamer

The BB2055 spiral-flute solid carbide reamer covers nominal diameters from 2 to 20 mm for precision finishing of prepared holes in steel and general metal machining. Compared with straight-flute designs, the spiral flute geometry provides a different chip-flow path and can be advantageous where smoother cutting and controlled chip evacuation are required.

Key Features

• BB2055 coated carbide grade for steel and general metal machining
• Spiral flute geometry for controlled chip evacuation
• Suitable for final hole sizing and surface finishing
• Solid carbide construction
• Multiple length and flute-count configurations

How to Choose

Select the required nominal diameter first. Then choose the shortest practical tool length that reaches the machining position. Verify the complete dimensions and flute count before ordering.

Application Notes

Use only on a prepared hole. Reaming allowance, speed, feed and coolant conditions should be selected according to workpiece material, machine and setup.
