Unique HSS Adjustable Hand Reamer

The U372 Adjustable Hand Reamer is a high-precision tool engineered for enlarging or finishing existing holes to specific, non-standard dimensions. By utilizing adjustable HSS (High-Speed Steel) blades, this reamer provides exceptional versatility, allowing the machinist to achieve precise fits that fixed-diameter reamers cannot reach.

Unique HSS Adjustable Hand Reamer

This is a "multi-size" finishing tool. Instead of buying a dozen different reamers for different hole sizes, you can adjust the blades on this one tool to hit the exact size you need. It's built from high-speed steel so it stays sharp, and it's perfect for fine-tuning holes to get that "perfect fit."
