Hertel 2291243 Chucking Reamer 24 0.1520 in Hss Straight

Product Description

The HERTEL 2291243 is a straight-flute chucking reamer ground to a wire gauge size 24 diameter of 0.1520 inches. Made from high-speed steel (HSS) with a bright, uncoated finish, this reamer is designed to finish-ream pre-drilled holes to precise tolerances in a machine tool setup. The straight-cylindrical shank seats directly in a drill chuck or collet, making it compatible with drill presses, lathes, and CNC machining centers. With a 4.0-inch overall length and a 1-inch flute length, it is suited to shallow-hole reaming applications where dimensional accuracy and surface finish are the primary requirements. Right-hand cutting direction is standard for conventional machine operation.

This chucking reamer is used in metalworking and light industrial machining environments where holes in the 0.1500 to 0.1999 inch diameter range require final sizing. Typical applications include fixture work, jig boring, and production runs where hole tolerances are tight. The wire size 24 designation makes it a common choice when working with small-diameter pins, dowels, or precision fastener clearance holes. It is installed by machinists and tool and die professionals in job shops and manufacturing facilities.

Key Features

• Wire gauge size 24 reamer diameter of 0.1520 inches for precise small-hole finishing
• High-speed steel (HSS) construction for durability across a range of ferrous and non-ferrous materials
• Bright, uncoated finish suitable for general-purpose reaming without specialized lubrication requirements
• Straight-cylindrical shank for direct chucking in standard drill chucks and collets
• Straight flute design for clean chip evacuation in through-hole and shallow blind-hole applications
• Right-hand cutting direction compatible with standard machine spindle rotation

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and machining centers equipped with a drill chuck or collet capable of holding a straight-cylindrical shank in the 0.1520 inch diameter range.

Installation Notes

This reamer is installed by machinists and should be secured firmly in a drill chuck or collet before operation. Always ensure the machine spindle is fully stopped and locked out before changing or adjusting the tool. Use appropriate cutting fluid for the workpiece material to extend tool life and improve hole finish. Do not use a chucking reamer to remove excessive stock — pre-drill or bore the hole to near-final size before reaming.
