BB2055 Straight Flute Solid Carbide Reamer for Steel | 8.1–20mm

BB2055 Straight Flute Solid Carbide Reamer

The BB2055 straight-flute solid carbide reamer is designed for precision final sizing of prepared holes from 8.1 to 20 mm in steel and general metal machining. The straight-flute geometry provides stable guidance and a rigid cutting form for controlled reaming.

Key Features

• BB2055 coated carbide series for steel and general metal machining
• Straight flute geometry for stable guidance
• Suitable for precision hole sizing and finishing
• Multiple diameter and length configurations

Straight vs. Spiral Flute

Straight-flute reamers emphasize stable guidance and simple chip paths. Spiral-flute reamers use a helical flute path to influence chip flow and cutting smoothness. Select according to hole type, chip direction, material and machine setup.

Application Notes

Use on a prepared hole only. Reaming allowance, cutting speed, feed and coolant should be selected according to the actual workpiece and machining conditions.
