This BB2055 PRO micro reamer is designed for precision finishing of very small prepared holes from 0.5 to 2.22 mm in steel and general metal machining. The spiral-flute geometry supports smooth cutting and controlled chip movement, while the coated carbide construction improves wear resistance for repeated CNC use.
Key Features
Micro-size range from 0.5 to 2.22 mm
BB2055 coated carbide series
Spiral flute geometry for controlled chip flow
Designed for final sizing after drilling or boring
Suitable for CNC precision machining
Selection & Use
Choose the exact finished-hole diameter, then verify shank, flute length, overall length and flute count. Minimize tool overhang. Use only on a prepared hole; actual allowance and cutting parameters depend on the workpiece, machine and setup.
