Hertel 8272288 Chucking Reamer 55/64 in Hss 8 Flute

Product Description

The HERTEL 8272288 is a straight-flute chucking reamer designed for precision hole finishing in metalworking applications. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing in through-holes and blind holes where tight tolerances are required. The reamer measures 55/64 inches (0.8594 inches decimal) in diameter with a 10-inch overall length and a 2-5/8 inch flute length. The straight-cylindrical shank seats securely in standard drill press chucks, CNC lathes, or milling machine collets. Eight right-hand cutting flutes distribute cutting load evenly, reducing chatter and improving surface finish. This tool is intended for use by machinists and tool-and-die professionals working in ferrous and non-ferrous materials.

This chucking reamer is suited for machine reaming operations in job shops, production machining environments, and maintenance repair settings. It is appropriate for use in drill presses, lathes, and machining centers where a straight-cylindrical shank tool is required. The 55/64-inch diameter places it in the 0.7000 to 0.9999 inch reamer diameter range, making it applicable to medium-bore finishing work across a broad range of component types including bushings, bearing bores, and precision-fit pin holes.

Key Features

• 55/64 inch (0.8594 inch decimal) diameter for precise medium-bore hole finishing
• HSS construction provides toughness and wear resistance across a range of workpiece materials
• 8 straight right-hand flutes for even cutting load distribution and smooth surface finish
• Bright/uncoated finish suitable for use with standard cutting fluids
• Straight-cylindrical shank compatible with standard chucks and collets
• 10-inch overall length with 2-5/8 inch flute length for reach in deeper bores

Compatibility

Designed as an OEM-style machine reamer for use in drill presses, engine lathes, turret lathes, and CNC machining centers that accept straight-cylindrical shank tooling in the 0.7000 to 0.9999 inch diameter range.

Installation Notes

This tool should be installed and operated by qualified machinists familiar with machine reaming procedures. Secure the straight-cylindrical shank firmly in a chuck or collet before use and verify runout with a dial indicator prior to cutting. Always apply appropriate cutting fluid for the workpiece material and never run a reamer in reverse, as this will damage the cutting edges. Follow applicable shop safety procedures and machine guarding requirements during operation.
