Hertel 2290187 Chucking Reamer 9/32 in Hss 6 Flute

Product Description

The HERTEL 2290187 is a straight-flute chucking reamer designed for precision hole finishing in metal and other materials. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers accurate sizing and smooth bore surfaces in production and maintenance machining environments. It measures 9/32 inch (0.2812 inch decimal) in diameter with a 6-inch overall length and a 1-1/2 inch flute length. The straight-cylindrical shank seats securely in standard drill chucks and collets. Machinists, tool-and-die workers, and maintenance technicians use this reamer to bring drilled or bored holes to final tolerance.

This chucking reamer is suited for light-to-medium reaming operations on ferrous and non-ferrous workpieces in job shops, production floors, and general maintenance facilities. The right-hand cutting direction makes it compatible with standard CNC machining centers, knee mills, drill presses, and lathes. Its 9/32 inch diameter targets through-hole and blind-hole finishing in the 0.2500 to 0.2999 inch range, a common size bracket for fastener clearance holes and dowel pin fits where tight tolerances are required.

Key Features

• HSS construction provides heat resistance and durability for general-purpose reaming operations
• 6 straight flutes produce consistent, smooth finishes and efficient chip evacuation
• Bright uncoated finish suits a wide range of workpiece materials without added friction from coatings
• Straight-cylindrical shank fits standard chucks and collet holders without adapters
• Right-hand cutting direction compatible with conventional machine tool spindle rotation
• Decimal diameter of 0.2812 inch provides accurate sizing within the 0.2500 to 0.2999 inch range

Compatibility

Designed as an OEM-style replacement or standard replacement for straight-shank chucking reamers in the 9/32 inch diameter class, compatible with drill chucks and ER collet systems that accept straight-cylindrical shanks.

Installation Notes

Install in a drill press, mill, or lathe with the spindle fully de-energized and locked out before securing the shank in the chuck or collet. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Ensure the workpiece is clamped securely to prevent movement during the reaming pass. Follow applicable shop safety standards and machine tool operating procedures when selecting feed rate and spindle speed.
