Frequently Asked Questions

What is the OSG Chucking Reamer 300-0551 used for?

The OSG Chucking Reamer 300-0551 is a straight-flute solid carbide reamer used for precision hole finishing in metalworking. It achieves tight tolerances and smooth surface finishes in production machining, tool and die making, and maintenance applications. Its carbide construction provides wear resistance for extended tool life.

What are the specifications of the OSG Chucking Reamer 300-0551?

The OSG Chucking Reamer 300-0551 has a diameter of 0.0551 in (1.4 mm), straight flute design, and is made of solid carbide. It is a chucking reamer with a straight shank, designed for machine use. The manufacturer part number is 300-0551, and it is produced by OSG.

Where to buy the OSG Chucking Reamer 300-0551 worldwide?

You can source the OSG Chucking Reamer 300-0551 through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply this precision reamer to customers across industries.

How to select the correct OSG Chucking Reamer for a job?

To select the correct OSG chucking reamer, match the reamer diameter to the finished hole size required, typically leaving 0.005–0.015 in for reaming. Consider material hardness and desired surface finish; solid carbide reamers like the 300-0551 suit harder materials. Ensure machine spindle speed and feed rate align with OSG recommendations for optimal performance.
