Hertel 72037302 Chucking Reamer 0.73 in Hss 8 Flute

Product Description

The HERTEL 72037302 is a straight-flute chucking reamer designed for precision hole finishing in metal workpieces. It cuts at a 0.7300-inch diameter with an overall length of 9 inches and a 2.25-inch flute length, making it well-suited for through-hole and blind-hole reaming applications that require tight dimensional tolerances. Constructed from high-speed steel (HSS) with a bright, uncoated finish, this 8-flute reamer provides a smooth cutting action in right-hand rotation. It features a straight cylindrical shank for secure chuck or collet holding on drill presses, lathes, and CNC machining centers. Machinists and tool and die technicians are the primary users of this tool.

This reamer is used in machine shops, maintenance facilities, and production environments where hole size accuracy and surface finish are critical. It is appropriate for reaming ferrous and non-ferrous materials at moderate cutting speeds. The straight-flute geometry suits applications where chip evacuation through the flutes is acceptable and where coolant-assisted through-tool delivery is not required. The 9-inch overall length provides adequate reach for standard workpiece setups on common machine tool configurations.

Key Features

• 0.7300-inch reamer diameter for precise hole finishing
• 8 straight flutes for smooth, consistent stock removal
• High-speed steel (HSS) construction for durability across ferrous and non-ferrous materials
• Bright, uncoated finish suitable for general-purpose reaming
• Straight cylindrical shank compatible with standard chucks and collets
• Right-hand cutting direction for conventional machine spindle use

Compatibility

Designed as an OEM-style chucking reamer for use in drill presses, engine lathes, turret lathes, and CNC machining centers equipped with a straight-cylindrical chuck or collet capable of holding a 0.7300-inch shank diameter tool.

Installation Notes

Installation and operation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before mounting or removing the reamer from the chuck or collet. Ensure the shank is fully seated and the chuck is properly tightened before beginning a cut. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish quality.
