Hertel 2350122 Chucking Reamer 3/16 in Hss 6 Flute

Product Description

The HERTEL 2350122 is a high-speed steel (HSS) chucking reamer designed to finish-ream drilled holes to close tolerances. With a 3/16 inch (0.1875 inch decimal) diameter, the tool removes minimal material to produce a smooth, accurate bore suitable for dowel pins, bearings, and precision-fit assemblies. The 6-flute spiral design with right-hand cut and right-hand spiral direction provides a smooth cutting action and consistent chip evacuation. The bright, uncoated finish is standard for HSS reamers used in general-purpose ferrous and non-ferrous applications. A straight-cylindrical shank seats directly in a drill chuck or collet holder.

This reamer is suited for machine shop, toolroom, and production environments where hole quality and dimensional accuracy are required. It is appropriate for use in drill presses, CNC machining centers, lathes, and manual turret machines. Machinists, tool and die makers, and maintenance technicians use chucking reamers of this type when a drilled hole must be brought to a precise finish diameter. The 1-1/8 inch flute length accommodates typical through-hole and shallow blind-hole reaming at this diameter range.

Key Features

• 3/16 inch (0.1875 inch) reamer diameter in the 0.1500 to 0.1999 inch decimal range
• HSS tool material provides toughness and resharpening capability across common workpiece materials
• 6-flute spiral configuration for smooth cutting action and efficient chip flow
• Right-hand cut and right-hand spiral direction — compatible with standard machine spindle rotation
• Bright, uncoated finish — no coating to affect as-ground diameter tolerance
• Straight-cylindrical shank for direct chuck or collet mounting without adapters

Compatibility

Designed as a standard chucking reamer for use in any machine tool spindle that accepts a straight-cylindrical shank at this diameter, including drill presses, lathes, and milling machines equipped with an appropriate drill chuck or collet system.

Installation Notes

This reamer is a machine-held cutting tool and must be installed by a qualified machinist or toolroom technician. Secure the straight shank firmly in a drill chuck or collet with minimal runout before use — excessive runout will degrade hole finish and shorten tool life. Always apply appropriate cutting fluid for the workpiece material and ensure the machine spindle is at the correct speed before engaging the cut. Never use a chucking reamer as a hand reamer or apply side-loading forces to the fluted section.
