Hertel 85018182 Chucking Reamer 0.63 in Hss 8 Flute

Product Description

The HERTEL 85018182 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 a wide range of drilling and boring operations. The reamer measures 0.6300 inches in diameter with a 9-inch overall length and a 2.25-inch flute length. The straight-cylindrical shank allows secure clamping in standard drill chucks and machine tool holders. With 8 flutes and right-hand cutting direction, it produces a smooth, consistent bore finish in both manual and CNC machine setups. Machinists and tool-and-die professionals are the primary users of this tool.

This chucking reamer is suited for finishing through-holes and blind holes in ferrous and non-ferrous metals where tight diameter tolerances are required. It is commonly used in machine shops, maintenance facilities, and production environments. The 0.6300-inch diameter falls within the 0.5000 to 0.6999-inch decimal inch reamer diameter range, making it a standard selection for jobs requiring that sizing. It is not configured as a dowel pin reamer and is not an over or under size reamer, so it is intended for on-size hole finishing.

Key Features

• 0.6300-inch diameter for precise on-size hole finishing
• 8 straight flutes with right-hand cutting direction for smooth bore surfaces
• High-speed steel (HSS) construction for durability across common metals
• Bright, uncoated finish suitable for general-purpose reaming
• Straight-cylindrical shank fits standard chucks and collet holders
• 9-inch overall length with 2.25-inch flute length for reach and control

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and CNC machining centers that accept straight-cylindrical shank tooling in the 0.5000 to 0.6999-inch diameter range.

Installation Notes

This reamer is installed by a machinist or toolmaker in a compatible chuck or collet holder — ensure the shank is fully seated and securely clamped before operation. Power down or lock out the machine before changing tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Do not use this reamer to remove excessive stock; pre-drill or bore the hole to within a few thousandths of final size before reaming.
