Hertel 2291185 Chucking Reamer Wire 18 Hss 4.5in Oal

Product Description

The HERTEL 2291185 is a straight-flute chucking reamer designed to finish-ream holes to a precise wire gauge No. 18 diameter of 0.1695 inches. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it is built for use in drill presses, lathes, and CNC machines where a straight-cylindrical shank is chucked directly into a collet or drill chuck. The 4.5-inch overall length and 1.125-inch flute length make it suitable for through-holes and shallow blind holes in ferrous and non-ferrous materials. Right-hand cutting direction is standard for conventional machine setups.

This reamer is intended for precision hole-finishing operations in machine shops, maintenance facilities, and production environments. It is commonly used when a drilled hole must be brought to a tight tolerance for pin fits, dowel fits, or close-clearance fastener applications. The wire-size designation places the finished diameter in the 0.1500 to 0.1999 inch decimal range, making it appropriate for small-bore work in metal fabrication, tool and die, and general machining applications. Licensed machinists and toolroom technicians are the primary users.

Key Features

• Wire gauge No. 18 diameter: 0.1695 inches for precise small-bore finishing
• High-speed steel (HSS) construction for durability across ferrous and non-ferrous materials
• Bright, uncoated finish suitable for general-purpose reaming with standard cutting fluids
• Straight-cylindrical shank for direct chucking in collets, drill chucks, and machine spindles
• Straight flute geometry provides clean, consistent stock removal on through and shallow blind holes
• Right-hand cutting direction compatible with standard machine spindle rotation

Compatibility

Designed as an OEM-style chucking reamer for use in any machine tool accepting a straight-cylindrical shank in the corresponding diameter range, including drill presses, lathes, milling machines, and CNC machining centers.

Installation Notes

A licensed machinist or toolroom technician should install and operate this reamer. Secure the straight-cylindrical shank firmly in a collet or drill chuck before use, and verify runout is within acceptable tolerance to prevent bell-mouthing or chatter. Always apply an appropriate cutting fluid for the workpiece material to extend tool life and maintain hole-size accuracy. Power down and de-energize the machine spindle completely before changing or inspecting the reamer.
