Hertel 72019250 Chucking Reamer 0.1925 in Hss 6 Flute

Product Description

The HERTEL 72019250 is a straight-flute chucking reamer designed for precision hole finishing in machine tool applications. Ground from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers accurate bore sizing in a wide range of ferrous and non-ferrous materials. It features a 0.1925-inch cutting diameter, a 5-inch overall length, and a 1.25-inch flute length with 6 straight flutes cutting in a right-hand direction. The straight-cylindrical shank seats securely in drill chucks or collet holders, making it suitable for drill press, lathe, and milling machine setups where repeatable hole tolerance is required.

This reamer is intended for production and maintenance machining environments where holes need to be brought to a close-tolerance finished diameter. Typical applications include through-hole and blind-hole finishing in metal workpieces where a drilled hole has been left slightly undersize for reaming. The 0.1925-inch diameter places this tool in the 0.1500 to 0.1999-inch range, commonly used for dowel pin fits, bushings, and precision bearing bores in light manufacturing and toolroom work. It is installed by machinists and tool-and-die professionals using standard machine tool setups.

Key Features

• 0.1925-inch cutting diameter for precise hole finishing in the 0.15 to 0.1999-inch range
• HSS construction provides good wear resistance across a range of workpiece materials
• 6 straight flutes with right-hand cutting direction for smooth, chatter-resistant material removal
• Bright, uncoated finish suitable for use with cutting fluids on most common metals
• Straight-cylindrical shank for secure mounting in drill chucks or collet holders
• 5-inch overall length with 1.25-inch flute length for controlled engagement depth

Compatibility

Designed as an OEM-style chucking reamer for use in drill press, lathe, or milling machine setups requiring straight-cylindrical shank tooling in the 0.1925-inch finished bore diameter.

Installation Notes

Chucking reamers are installed by machinists and should be secured in a properly sized chuck or collet before use. Always power down and lock out the machine before changing tooling. Pre-drill or bore the hole to the recommended undersize before reaming to avoid tool deflection or premature edge wear. Use an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish.
