Hertel 72027154 Chucking Reamer 0.2715 in Hss Straight

Product Description

The HERTEL 72027154 is a straight-flute chucking reamer designed for precision hole finishing in metal components. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent bore sizing in drilling and machining operations. The reamer measures 0.2715 inches in diameter with a 6-inch overall length and a 1.5-inch flute length. Its straight-cylindrical shank seats securely in standard drill chucks and collets. With 6 flutes and a right-hand cutting direction, it produces a smooth, accurate finish in through-holes and blind holes on ferrous and non-ferrous materials. Machinists and tool-and-die tradespeople rely on this style of reamer for close-tolerance sizing work.

This chucking reamer is suited for general-purpose machine shop use, including manual lathes, drill presses, CNC machining centers, and mill setups where a final pass is needed to bring a bored or drilled hole to a precise finished diameter. The 0.2715-inch size falls within the 0.2500 to 0.2999-inch decimal inch diameter range, making it appropriate for reaming operations that require tight dimensional control in production and maintenance machining environments.

Key Features

• 0.2715-inch cutting diameter for precise hole finishing
• 6-inch overall length with 1.5-inch flute length
• High-speed steel (HSS) construction for durability on a wide range of workpiece materials
• Straight-cylindrical shank for compatibility with standard drill chucks and collets
• 6 straight flutes with right-hand cutting direction
• Bright, uncoated finish — no coating to affect dimensional tolerance

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and machining centers that accept a straight-cylindrical shank toolholder or drill chuck.

Installation Notes

Install in a properly sized drill chuck or collet and ensure the shank is fully seated before operation. Secure the workpiece firmly before reaming, and apply appropriate cutting fluid to extend tool life and improve surface finish. Always ream at a lower RPM than drilling, with a consistent feed rate, to avoid chatter and maintain dimensional accuracy. This tool is intended for use by qualified machinists familiar with speeds and feeds for HSS tooling.
