Hertel 2296754 Chucking Reamer 7.50mm Hss 6 Flute

Product Description

The HERTEL 2296754 is a straight-flute chucking reamer designed for precision hole finishing in metal workpieces. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent sizing in a 7.50 mm (0.2953 inch) diameter. The six-flute, right-hand cutting geometry provides smooth material removal and accurate bore geometry. With a 6-inch overall length and a straight-cylindrical shank, this reamer seats securely in standard drill chucks and collet holders on lathes, milling machines, and drill presses. Machinists and toolroom technicians use it for finish-reaming drilled or bored holes to close dimensional tolerances.

This chucking reamer is suited for general metalworking applications in job shops, production machining, and maintenance environments. It is appropriate for use in ferrous and non-ferrous materials where a smooth, accurately sized bore is required. The 1.5-inch flute length provides adequate chip clearance for through-holes and shallow blind bores in the 7.50 mm range. It is a single-piece unit packaged individually, making it a straightforward replacement or addition to a standard reamer set.

Key Features

• 7.50 mm (0.2953 inch) reamer diameter for precise hole finishing
• High-speed steel (HSS) construction for durability across a range of metals
• Six straight flutes with right-hand cutting direction
• Bright, uncoated finish — no coating buildup affecting final bore size
• Straight-cylindrical shank for compatibility with standard chucks and collets
• 6-inch OAL with 1.5-inch flute length for controlled chip evacuation

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks, collet chucks, and floating reamer holders on lathes, milling machines, and drill presses accepting a straight-cylindrical shank in the 0.2500 to 0.2999 inch diameter range.

Installation Notes

Installation is performed by machinists or toolroom technicians. Secure the straight-cylindrical shank firmly in a drill chuck or collet before use, and confirm runout is within acceptable limits before reaming to size. Always pre-drill or bore the hole to within the recommended stock allowance before introducing the reamer. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish.
