Hertel 72033046 Chucking Reamer 0.3040 in Hss Straight

Product Description

The HERTEL 72033046 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 consistent bore sizing and smooth surface finishes in ferrous and non-ferrous materials. The reamer measures 0.3040 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 collet holders. With 6 flutes and right-hand cutting direction, it provides efficient material removal and accurate final hole dimensions. Machinists and tool-and-die techs reach for this style of reamer when a drilled hole needs to be brought to a precise, finished diameter.

This chucking reamer is suited for use in drill presses, lathes, milling machines, and CNC machining centers where controlled feed rates and proper cutting fluid application are standard practice. It is appropriate for production runs or job-shop work requiring repeatable hole tolerances in the 0.3000 to 0.3499 inch diameter range. The bright HSS construction makes it a practical choice for general-purpose reaming where coated tooling is not required.

Key Features

• 0.3040 inch reaming diameter for precision bore finishing
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• 6-inch overall length with 1.5-inch flute length for reach and rigidity
• Straight-cylindrical shank compatible with standard chucks and collet holders
• 6-flute straight geometry with right-hand cutting direction
• Bright, uncoated finish suitable for general-purpose machining applications

Compatibility

Designed as a general-purpose chucking reamer for use in drill presses, lathes, milling machines, and CNC machining centers equipped with standard drill chucks or collet systems accepting a straight-cylindrical shank.

Installation Notes

Chucking reamers are installed and operated by machinists following standard machine shop practices. Before mounting, ensure the machine spindle and chuck or collet are clean and free of debris to prevent runout. Always apply appropriate cutting fluid for the workpiece material and operate at a feed rate and speed appropriate for HSS reaming. Never run a reamer in reverse, as this dulls the cutting edges rapidly.
