Hertel 72018351 Chucking Reamer 0.1835in Hss 6-flute

Product Description

The HERTEL 72018351 is a high-speed steel (HSS) chucking reamer designed to finish-size drilled or bored holes to precise tolerances. With a reamer diameter of 0.1835 inches and an overall length of 4.5 inches, this tool delivers accurate, repeatable hole sizing in metal workpieces. The 6-flute straight configuration and bright uncoated finish make it well-suited for general-purpose reaming in ferrous and non-ferrous materials. Machinists and toolroom professionals use this reamer in CNC machining centers, manual lathes, and drill presses where close-tolerance hole finishing is required.

This chucking reamer is appropriate for production and toolroom environments where hole diameter accuracy in the 0.1500 to 0.1999 inch range is critical. The straight-cylindrical shank allows direct mounting in standard chucks and collets. Right-hand cutting direction is standard for conventional spindle rotation. The 1.125-inch flute length provides adequate chip clearance for typical hole depths in this diameter range.

Key Features

• HSS construction provides toughness and wear resistance for general-purpose hole finishing
• 6-flute straight geometry delivers smooth surface finish and accurate sizing
• Bright uncoated finish suits a wide range of workpiece materials without added friction from coatings
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight-cylindrical shank seats securely in standard drill chucks and collets
• Overall length of 4.5 inches accommodates common setup clearances in lathes and machining centers

Compatibility

Designed as an OEM-style chucking reamer for use in any machine tool equipped with a chuck or collet capable of accepting a straight-cylindrical shank in this diameter range.

Installation Notes

Installation should be performed by a qualified machinist. Ensure the machine spindle is fully stopped and the chuck is properly tightened before beginning any reaming operation. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Pre-drill the hole to the recommended undersize before reaming to avoid overloading the flutes.
