Hertel 2298552 Chucking Reamer 1.0039 in Hss Straight Shank

Product Description

The HERTEL 2298552 is a high speed steel chucking reamer designed for precision hole finishing in metalworking and machining applications. It features a 1.0039-inch (25.50 mm) diameter with a straight shank and straight flute geometry. The bright polished finish reduces friction during cutting. With 8 flutes and a 2.75-inch flute length, it delivers clean, accurate bores in a single pass. Overall length is 10.5 inches, making it suitable for use in CNC machining centers, manual lathes, and drill presses where chuck-held tooling is standard. Right-hand cutting direction aligns with conventional spindle rotation. This tool is installed and operated by machinists and tool-and-die professionals.

This chucking reamer is suited for finishing pre-drilled or bored holes to tight dimensional tolerances in ferrous and non-ferrous metals. Its straight flute design performs well in through-hole and blind-hole applications where chip evacuation is managed by coolant or chip-clearing passes. The 1.0039-inch nominal diameter corresponds to the 25.50 mm metric equivalent, making it useful in shops bridging inch and metric workflows. Typical applications include fixture work, jig boring, and production reaming where hole roundness and surface finish are critical requirements.

Key Features

• 1.0039-inch (25.50 mm) reamer diameter for precision hole finishing
• High speed steel construction for durability across a range of work materials
• 8-flute straight geometry for consistent surface finish and dimensional accuracy
• Bright polished coating reduces friction and aids chip flow
• Right-hand cutting direction compatible with standard spindle rotation
• Straight shank for direct chuck mounting on lathes, drill presses, and machining centers

Compatibility

Designed as an OEM-style chucking reamer for use in any machine tool spindle or chuck accepting a straight-shank tool at the stated shank diameter.

Installation Notes

Chucking reamers are installed and operated by qualified machinists. Power down and lock out the machine spindle before mounting or removing the tool. Secure the straight shank firmly in the chuck to prevent runout, and verify shank concentricity before cutting. Always use appropriate cutting fluid for the work material to extend tool life and maintain bore quality.
