Hertel 62054804 Chucking Reamer 0.3615 in Hss 6 Flute

Product Description

The HERTEL 62054804 is a straight-flute chucking reamer designed for precision hole finishing in metal machining applications. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers accurate sizing at 0.3615 inches in diameter. The straight-cylindrical shank seats securely in standard drill chucks or collet holders, making it a reliable choice for CNC machines, drill presses, and manual lathes. At 7 inches overall length with a 1.75-inch flute length, it handles moderate-depth finishing passes with six right-hand cutting flutes for clean, consistent bore tolerances.

This chucking reamer is suited for production and maintenance machine shops working with ferrous and non-ferrous metals where tight bore tolerances are required. It is used by machinists and toolroom technicians to bring drilled or bored holes to final size. The 0.3615-inch diameter falls within the 0.3500 to 0.3999 inch reamer diameter range, making it appropriate for applications requiring a close slip or light press fit in that size class. It is sold individually with a minimum order quantity of one.

Key Features

• 0.3615-inch diameter for precise hole finishing within the 0.3500 to 0.3999 inch range
• High-speed steel (HSS) construction for durability across common machining materials
• 6 straight flutes with right-hand cutting direction for smooth, accurate bore sizing
• Bright, uncoated finish suitable for general-purpose machining without added coating costs
• Straight-cylindrical shank for compatibility with standard drill chucks and collet holders
• 7-inch overall length with 1.75-inch flute length for moderate-depth reaming passes

Compatibility

Designed as a standard chucking reamer for use in drill presses, CNC machining centers, turret lathes, and manual lathes equipped with drill chucks or collet holders accepting a straight-cylindrical shank.

Installation Notes

Chucking reamers are installed and operated by machinists. Ensure the machine spindle is fully stopped and the workpiece is securely fixtured before changing tooling. Seat the straight-cylindrical shank fully in the chuck or collet and verify runout before cutting. Always apply appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality.
