BB2055 PRO Spiral Flute Carbide Reamer for Steel | 11–12.1mm

BB2055 PRO Spiral Flute Carbide Reamer

This BB2055 PRO spiral-flute solid carbide reamer is designed for precision finishing of prepared holes from 11 to 12.1 mm in steel and general metal machining. The coated carbide grade supports wear resistance, while the spiral flute geometry provides controlled chip movement and smooth cutting in suitable CNC applications.

Key Features

• BB2055 PRO coated carbide series
• Spiral flute geometry for chip control
• Precision diameter range from 11 to 12.1 mm
• Solid carbide construction for rigidity

Selection & Use

Select the nominal diameter according to the required finished hole size, then verify shank diameter, flute length, overall length and flute count. Use only on an existing prepared hole. Actual allowance and cutting parameters depend on material, machine rigidity and setup.
