BB2055 Straight Flute Solid Carbide Reamer
Precision solid carbide reamer for CNC hole finishing in the 8.01–10.99 mm diameter range. The straight-flute geometry is designed for controlled finishing of existing holes where stable sizing and repeatable surface quality are required.
Key Features
Solid carbide construction: provides rigidity for precision hole finishing.
Straight flute design: supports stable guidance and consistent reaming in pre-machined holes.
Fine diameter selection: multiple precision diameters are available within the listed range.
6-flute variants: listed larger-diameter options use 6T geometry.
Typical Applications
Final sizing of drilled or bored holes
Precision CNC reaming
Improving hole consistency and surface finish
General engineering components requiring accurate finished-hole dimensions
How to Read the Size
Variant dimensions are shown in a format such as 8.01×40×75×6T. The first value is the nominal reamer diameter, followed by the listed length dimensions and flute count.
Machining Notes
Use a consistent pre-hole allowance and minimize spindle, collet and holder runout. Reaming parameters should be selected according to workpiece material, required tolerance, coolant or lubrication method and machine rigidity. Avoid using the reamer as a primary drilling tool.
