Hertel 72021058 Chucking Reamer 0.2105 in Hss 6 Flute

Product Description

The HERTEL 72021058 is a straight-flute chucking reamer designed to finish-size drilled or bored holes to a precise 0.2105-inch diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers clean, accurate bore geometry in a wide range of workpiece materials. It features a straight-cylindrical shank for secure seating in standard drill chucks or collet holders. With an overall length of 5 inches and a 1.25-inch flute length, the tool is well-suited for moderate-depth finishing passes on the mill, drill press, or lathe. Licensed machinists and toolroom technicians are the primary users of this type of precision cutting tool.

This chucking reamer is intended for use in precision machining environments where hole tolerances require a finishing operation beyond what a drill alone can achieve. The right-hand cutting direction and six-flute configuration produce a smooth bore surface finish while maintaining dimensional accuracy. Typical applications include production machining, toolroom work, and maintenance repair operations where a 0.2105-inch finished bore diameter is required. The straight flute geometry makes it a reliable choice for through-holes and shallow blind holes in ferrous and non-ferrous materials.

Key Features

• 0.2105-inch finished bore diameter falls within the 0.2000 to 0.2499-inch decimal inch reamer diameter range
• High-speed steel (HSS) construction provides durability across a broad range of workpiece materials
• Six straight flutes with right-hand cutting direction for smooth, accurate bore finishing
• Bright, uncoated finish — no coating interference with tight-tolerance applications
• Straight-cylindrical shank seats directly in standard drill chucks and collet holders
• 5-inch overall length with 1.25-inch flute length suits moderate-depth through-holes and shallow blind holes

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks, collet holders, and floating reamer holders accepting a straight-cylindrical shank.

Installation Notes

This tool is installed and operated by machinists and toolroom technicians using drill presses, milling machines, or lathes. Always ensure the spindle and workpiece are fully stopped before changing or seating the reamer. The straight-cylindrical shank must be fully engaged and securely clamped in the chuck or collet before operation. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish quality.
