BB2055 Spiral Flute Solid Carbide Reamer for Steel | 2.95–5.49mm

BB2055 Spiral Flute Solid Carbide Reamer

The BB2055 spiral-flute solid carbide reamer is designed for precision finishing and final sizing of prepared holes in steel and general metal machining applications. The coated BB2055 series is positioned for higher wear resistance than the BF series, while the spiral flute geometry supports smooth cutting and controlled chip evacuation.

Key Features

• BB2055 coated carbide series for steel and general metal machining
• Spiral flute geometry for smoother cutting and chip control
• Designed for precision hole sizing after drilling or boring
• Solid carbide construction for rigidity and wear resistance
• Available in fine diameter increments for accurate selection

Selection

Choose the nominal diameter according to the required finished hole size, then confirm flute length, overall length, shank size and flute count. Avoid unnecessary extra reach where possible.

Application Notes

A reamer finishes an existing hole; it does not replace a drill. Actual reaming allowance and cutting conditions depend on workpiece material, machine rigidity, tool holding and hole geometry.
