Hertel 45675881 Chucking Reamer 0.296 in Solid Carbide

Product Description

The HERTEL 45675881 is a solid carbide chucking reamer designed for precision hole finishing in metalworking applications. With a reamer diameter of 0.296 inches and a straight shank configuration, this tool fits standard drill chucks and collet holders commonly used in machining centers, drill presses, and lathes. The 6-flute right-hand cutting geometry distributes cutting load evenly across the workpiece, reducing chatter and improving surface finish. The bright polished finish minimizes friction and aids chip evacuation. At 3.25 inches overall length with a 1.125-inch flute length, the 45675881 is suited for through-hole and blind-hole reaming operations in ferrous and non-ferrous materials where tight diameter tolerances are required.

This chucking reamer is intended for production and toolroom environments where repeatable hole sizing is critical. It is commonly used by machinists, tool and die makers, and precision fabricators working in job shops, manufacturing facilities, and maintenance repair operations. Typical applications include reaming pre-drilled pilot holes to final diameter in steel, cast iron, aluminum, and similar materials. The straight shank design allows quick changeover between setups without specialized toolholding equipment.

Key Features

• Solid carbide construction provides rigidity and wear resistance for extended tool life in hard materials
• 6-flute right-hand cutting geometry delivers a smooth, consistent bore finish
• Straight shank fits standard chucks and collet holders without adapters
• Bright polished finish reduces friction and assists chip flow during cutting
• 0.296-inch diameter falls within the 0.2500 to 0.2999-inch decimal inch reamer range
• Compact 3.25-inch overall length suits short-reach and bench-machine setups

Compatibility

Designed as a straight-shank chucking reamer for use in standard drill chucks, ER collets, and similar toolholding systems on drilling and milling equipment accepting a 0.296-inch shank diameter tool.

Installation Notes

This reamer is installed and serviced by machinists following standard machine tool procedures. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before mounting. Secure the straight shank firmly in the chuck or collet to the appropriate holding depth to prevent runout. Use appropriate cutting fluid for the workpiece material to maximize tool life and surface finish quality.
