BB2055 Straight Flute Solid Carbide Reamer | 11.01–12.09mm

BB2055 Straight Flute Solid Carbide Reamer

Precision carbide reamer for CNC hole finishing in the 11.01–12.09 mm diameter range. The straight-flute, 6-flute geometry is intended for finishing pre-drilled or pre-bored holes where dimensional consistency and surface quality are important.

Key Features

• Solid carbide construction: provides rigidity and wear resistance for precision reaming.
• Straight flute geometry: supports stable guidance in existing holes.
• 6-flute design: provides multiple cutting edges for controlled finishing.
• Fine diameter selection: sizes are available in small increments across the listed range.

Typical Applications

• Final sizing of drilled or bored holes
• Precision CNC hole finishing
• Improving dimensional repeatability and surface finish
• General engineering components requiring accurate finished-hole sizes

How to Read the Size

Variant dimensions are shown in a format such as 11.01×40×75×6T. The first value is the nominal reamer diameter, followed by the listed length dimensions and flute count.

Machining Notes

Use this tool as a finishing reamer rather than a primary cutting tool. Maintain a consistent pre-hole allowance, minimize toolholder runout and select speed, feed and lubrication according to material, machine rigidity and tolerance requirements.
