Frequently Asked Questions

What is an OSG chucking reamer used for?

An OSG chucking reamer is used to precisely enlarge and finish drilled holes to tight tolerances. It is commonly applied in metalworking, mold making, and automotive manufacturing where high accuracy and surface finish are required. The straight-flute design is ideal for through holes and general-purpose reaming in ferrous and non-ferrous materials.

What are the specifications of the OSG Chucking Reamer 300-2040?

The OSG Chucking Reamer 300-2040 has a 0.204 in diameter, #6 size, straight-flute design, and is made of solid carbide. It is manufactured by OSG under MPN 300-2040. This tool is designed for precision reaming operations in industrial settings, offering durability and consistent hole sizing.

How to select the correct OSG chucking reamer size?

To select the correct OSG chucking reamer, match the reamer diameter to your finished hole size, typically leaving 0.005–0.015 in for reaming allowance. Ensure the shank fits your machine's chuck. For the 300-2040, the 0.204 in diameter suits #6 screw holes. Consult OSG's technical data for material-specific speeds and feeds.
