BB2055 Straight Flute Solid Carbide Reamer for Steel | 1.0–8.0mm

BB2055 Straight Flute Solid Carbide Reamer

The BB2055 straight-flute solid carbide reamer is designed for precision final sizing of prepared holes from 1.0 to 8.0 mm in steel and general metal machining. Straight flutes provide stable guidance and a simple, rigid cutting geometry for controlled reaming.

Key Features

• BB2055 coated carbide series for steel machining
• Straight flute geometry for stable guidance
• Suitable for precision hole sizing and finishing
• Solid carbide construction
• Fine diameter range for small-hole applications

Straight vs. Spiral Flute

Straight-flute reamers emphasize stable guidance and straightforward cutting geometry. Spiral-flute reamers use a helical flute path to influence chip flow and cutting smoothness. Selection should be based on hole type, chip direction, workpiece material and the actual setup rather than flute style alone.

Application Notes

Use only on an existing prepared hole. Cutting parameters and reaming allowance should be selected for the actual machining conditions.
