BF2055 Spiral Flute Solid Carbide Reamer for Aluminum
Precision carbide reamer for finishing pre-drilled or pre-bored holes from 2.23 to 4.09 mm. This BF2055 series combines spiral-flute geometry with external coolant for CNC hole-finishing applications in aluminum and similar non-ferrous machining conditions.
Key Features
Solid carbide construction: provides rigidity and wear resistance for precision reaming.
Spiral flute geometry: supports progressive cutting and chip movement during finishing.
External coolant: designed for setups using conventional coolant delivery around the tool.
Fine diameter coverage: many sizes are available in 0.01 mm increments.
4-flute design: the listed variants use 4T geometry.
Typical Applications
Precision hole finishing in aluminum components
Final sizing of pre-drilled or pre-bored holes
CNC machining where external coolant is used
Small-diameter production reaming requiring close size selection
How to Read the Size
Variants use formats such as 2.23×D4×15×25×50-4T. The first value is the nominal reamer diameter, followed by the listed shank and length dimensions and flute count.
Machining Notes
Maintain a suitable and consistent reaming allowance, use rigid low-runout toolholding and provide reliable external coolant or lubrication. Cutting speed and feed should be selected according to workpiece material, hole condition and target tolerance.
