Hertel 72038581 Chucking Reamer 0.8580 in Hss 8 Flute

Product Description

The HERTEL 72038581 is a chucking reamer designed for precision hole finishing in metalworking and machining applications. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent bore sizing across a wide range of materials. The reamer measures 0.8580 inches in diameter with a 10 inch overall length and a 2-5/8 inch flute length. Eight straight flutes cut in a right-hand direction, providing smooth material removal and a clean, accurate bore. The straight-cylindrical shank seats securely in standard drill chucks and floating holders for reliable runout control during operation.

This chucking reamer is suited for production and maintenance machining environments where bore tolerance and surface finish are critical. It fits into standard machine tool setups including drill presses, CNC machining centers, turret lathes, and manual knee mills. A diameter range classification of 0.7000 to 0.9999 inches positions this tool in the mid-range bore sizing category, making it a common selection for through-holes and blind holes requiring close-tolerance finishing passes.

Key Features

• 0.8580 inch finished bore diameter for close-tolerance hole sizing
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• 8 straight flutes with right-hand cutting direction for smooth, consistent stock removal
• Bright, uncoated finish — no coating buildup to affect dimensional accuracy
• Straight-cylindrical shank compatible with standard drill chucks and floating reamer holders
• 10 inch overall length with 2-5/8 inch flute length for reach into moderate-depth bores

Compatibility

Designed as a standard chucking reamer for use in machine tool setups that accept a straight-cylindrical shank, including drill presses, lathes, and machining centers requiring 0.8580 inch finished bore diameter.

Installation Notes

Chucking reamers are installed and operated by machinists and toolroom technicians. Secure the straight-cylindrical shank firmly in a drill chuck or floating holder to minimize runout before engaging the workpiece. Always reduce spindle speed relative to drilling operations and apply appropriate cutting fluid for the workpiece material to extend tool life and improve bore finish. Do not reverse spindle rotation while the flutes are engaged in the bore, as this will damage the cutting edges.
