Hertel 72308901 Chucking Reamer Set 60 Piece Cobalt Steel

Product Description

The HERTEL 72308901 is a 60-piece chucking reamer set covering wire gauge sizes 1 through 60. Each reamer features a straight flute geometry with a right-hand cut, ground from cobalt steel for extended tool life in production and job-shop environments. The set is intended for precision hole finishing in metal workpieces where tight tolerances and smooth bore finishes are required. Machinists and toolroom technicians use chucking reamers in drill presses, lathes, and machining centers to bring drilled or bored holes to final dimension. Cobalt steel construction provides added heat and wear resistance compared to standard high-speed steel, making the set suited for harder ferrous materials and higher-speed applications.

This reamer set is used in metalworking and machining operations across manufacturing, maintenance, and repair environments. The full size range from 1 to 60 wire gauge covers a wide spectrum of small-diameter hole finishing tasks, reducing the need for individual reamer procurement. Typical applications include sizing holes for pins, bushings, and close-tolerance fasteners in both production runs and one-off toolroom work. The set is appropriate for use by machinist trades in industrial, commercial, and precision maintenance settings.

Key Features

• Full wire gauge range sizes 1 through 60 in a single set
• Straight flute design suitable for through-holes and general reaming operations
• Right-hand cut for standard spindle rotation on drill presses, lathes, and CNC equipment
• Cobalt steel construction for improved heat resistance and extended tool life over standard HSS
• 60-piece set reduces downtime from sourcing individual sizes

Compatibility

Designed for use in standard chucking reamer applications on drill presses, engine lathes, turret lathes, and machining centers that accept straight-shank tooling in wire gauge sizes 1 through 60.

Installation Notes

Chucking reamers are installed by machinist trades using an appropriate collet, drill chuck, or toolholder rated for the reamer shank diameter. Ensure the spindle and workpiece are properly secured before operation. Use recommended cutting fluids for the workpiece material to maintain reamer edge life and achieve target surface finish. Inspect each reamer for runout before use to avoid oversized or out-of-round bores.
