Hertel 72296122 Chucking Reamer 0.1260 in 4 Flute Hss

Product Description

The HERTEL 72296122 is a high-speed steel (HSS) chucking reamer designed for precision hole finishing in metalworking applications. With a reamer diameter of 0.1260 inches and a 0.1260 O/S oversize designation, this tool is built to bring bored or drilled holes to a controlled final diameter. The spiral flute geometry with right-hand cutting direction promotes smooth chip evacuation and consistent surface finish. The straight-cylindrical shank seats securely in standard drill chucks or collet holders. This reamer is well-suited for use in manual or CNC drilling operations where dimensional accuracy and finish quality are required.

This chucking reamer is intended for precision reaming operations in machine shop, toolroom, and production environments. The 7/8 inch flute length and 2-3/4 inch overall length make it appropriate for shallow-to-moderate depth holes in ferrous and non-ferrous materials. It is typically used by machinists and tool-and-die professionals working on light-to-medium material removal to achieve tight hole tolerances. The bright, uncoated finish is suited for general-purpose cutting without the overhead of specialized coatings.

Key Features

• 0.1260 inch diameter with oversize designation for controlled final hole sizing
• 4-flute spiral design with right-hand cutting direction for efficient chip removal
• HSS construction provides durability across a range of ferrous and non-ferrous materials
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Bright/uncoated finish for general-purpose machining applications
• Compact 2-3/4 inch overall length suitable for tight workpiece setups

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill press, lathe, or CNC machining center setups that accept straight-cylindrical shank tooling in the applicable diameter range.

Installation Notes

This reamer is installed and operated by qualified machinists following standard machine tool safety procedures. Ensure the machine spindle is fully stopped and power is off before mounting or removing the tool from the chuck or collet. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Do not exceed the recommended feed and speed parameters for HSS tooling in the material being cut.
