Hertel 2292027 Chucking Reamer Letter B Hss 6 in Oal

Product Description

The HERTEL 2292027 is a straight-flute chucking reamer designed to finish-ream letter B diameter holes to a precise 0.2380 inch diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent dimensional accuracy in ferrous and non-ferrous materials. The straight-cylindrical shank allows secure mounting in standard drill chucks, collet chucks, or floating reamer holders. With a 6 inch overall length and a 1.5 inch flute length, this reamer is suited to general-purpose through-hole and blind-hole finishing operations requiring close tolerances.

This reamer is used in machine shop, maintenance, and production environments where holes must be brought to a precise finish diameter after drilling. It is appropriate for use in drill presses, milling machines, lathes, and CNC machining centers. Right-hand cutting direction is standard for conventional clockwise-spindle machines. Typical users include machinists, tool-and-die technicians, and maintenance professionals performing precision bore work on metal components.

Key Features

• Letter B nominal size — 0.2380 inch finished bore diameter
• High-speed steel (HSS) construction for durability across a wide range of workpiece materials
• Straight flute geometry suited to through-holes and most standard reaming applications
• Bright, uncoated finish — ready to use or accept aftermarket coatings
• Straight-cylindrical shank for compatibility with common chuck and collet toolholding systems
• Right-hand cutting direction matches standard clockwise-spindle machine tools

Compatibility

Designed as a general-purpose chucking reamer for use in any machine tool capable of accepting a straight-cylindrical shank tool; compatible with drill presses, lathes, milling machines, and machining centers equipped with standard drill chucks or collet holders sized for the shank diameter.

Installation Notes

A licensed machinist or qualified technician should mount the reamer securely in a properly sized chuck or collet before operation. Always power down and lock out the machine spindle before installing or removing the reamer. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Do not reverse spindle direction while the reamer is engaged in the workpiece, as this will damage the cutting edges.
