BB2055 PRO Micro Spiral Flute Carbide Reamer for Steel | 0.5–2.22mm

BB2055 PRO Micro Spiral Flute Carbide Reamer

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.
