Frequently Asked Questions

What is the OSG Chucking Reamer 300-1250 used for?

The OSG Chucking Reamer 300-1250 is a straight-flute solid carbide reamer used for precision hole finishing in metalworking. It enlarges and smooths existing holes to tight tolerances, commonly in automotive, aerospace, and general machining applications where surface finish and dimensional accuracy are critical.

What are the specifications of the OSG Chucking Reamer 300-1250?

The OSG Chucking Reamer 300-1250 has a 0.125 in diameter, 1/8 in shank, straight flute design, and is made of solid carbide. The manufacturer part number is 300-1250. It is designed for use in drill chucks or collets on milling machines and drill presses for reaming operations.

Where to buy the OSG Chucking Reamer 300-1250 worldwide?

You can source the OSG Chucking Reamer 300-1250 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 OSG reamer to procurement teams and engineers internationally.

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

Select the OSG Chucking Reamer based on hole diameter, material, and tolerance. For the 300-1250, use it for 0.125 in finished holes in steel or cast iron. Ensure the reamer diameter matches the desired hole size, and use proper speeds and feeds per OSG recommendations to avoid chatter and achieve a smooth finish.
