BF2045 Spiral Flute Carbide Reamer for Aluminum | 4.01–4.99mm

BF2045 Spiral Flute Carbide Reamer for Aluminum | 4.01–4.99mm

The BF2045 spiral-flute solid carbide reamer is designed for precision finishing and final sizing of prepared holes in aluminum, aluminum alloys, copper and other relatively low-hardness non-ferrous materials. Available in nominal diameters from 4.01–4.99 mm, depending on the selected variant.

Key Features

• BF2045 carbide grade positioned for aluminum and low-hardness non-ferrous materials
• Designed for precision hole sizing and finishing after drilling or boring
• Solid carbide construction for good rigidity and wear resistance
• Spiral flute geometry for smooth cutting and controlled chip evacuation
• Multiple diameter, length and flute-count configurations available

How to Choose

Select the nominal diameter according to the required finished hole size. Then choose a length that reaches the machining position while allowing for hole depth and setup clearance. Avoid unnecessary extra reach where possible. Before ordering, verify the complete variant dimensions and flute count rather than selecting by diameter alone.

Application Notes

A reamer is used to finish an existing prepared hole; it is not a substitute for drilling directly into solid material. Reaming allowance, spindle speed, feed rate and coolant conditions should be selected according to the workpiece material, machine rigidity, hole size, hole depth and actual machining setup.

Recommended materials: aluminum, aluminum alloys, copper, copper alloys and similar relatively low-hardness non-ferrous materials.
