BB2055 H8 Straight Flute Solid Carbide Reamer

General-purpose solid carbide machine reamer covering nominal diameters from 2 to 20 mm. The straight-flute geometry and H8 tolerance designation make this series suitable for controlled CNC hole finishing across a broad range of component sizes.

Key Features

• H8 tolerance series: intended for standardized finished-hole sizing.
• Solid carbide construction: offers rigidity and wear resistance for production reaming.
• Straight flute geometry: supports stable guidance in pre-drilled or pre-bored holes.
• Broad size range: multiple diameters and length options are available from 2 to 20 mm.

Typical Applications

• CNC finishing of pre-machined holes
• General engineering and production reaming
• Applications requiring H8-class finished-hole dimensions
• Short and extended-reach reaming depending on selected variant

Variant Format

Sizes are listed in formats such as 6×30×60×6T or 8×60×100×6T. The first value is the nominal reamer diameter, followed by the listed length dimensions and flute count.

Machining Notes

Use the reamer only after drilling or boring the hole to a suitable pre-size. Maintain consistent stock allowance, rigid toolholding and low runout. Cutting speed, feed and lubrication should be selected according to the workpiece material, target tolerance and machine condition.
