Hertel 2292019 Chucking Reamer Letter a Hss 6in Oal

Product Description

The HERTEL 2292019 is a straight-flute chucking reamer designed to finish-ream holes to a precise Letter A diameter of 0.2340 inches. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing in through-hole and blind-hole finishing operations on ferrous and non-ferrous materials. The straight-cylindrical shank seats directly in drill chucks, collet chucks, and floating holders without modification. With a 6-inch overall length and a 1.5-inch flute length, this reamer suits bench drill presses, knee mills, and CNC machining centers where controlled stock removal and close hole-tolerance work are required.

This reamer is a standard choice for machine shops, maintenance and repair facilities, and toolroom applications where Letter A holes must be held to tight dimensional tolerances. The right-hand cutting direction pairs with conventional clockwise spindle rotation. It is suited to moderate-speed, high-feed reaming in aluminum, mild steel, brass, and cast iron when used with appropriate cutting fluid. Operators typically reach for this size when producing clearance or transition fits in small-diameter bores.

Key Features

• Letter A (0.2340 inch) diameter for precise hole finishing in that size range
• High-speed steel (HSS) construction for durability across a broad range of workpiece materials
• Straight flute geometry promotes smooth chip evacuation in through-hole applications
• Bright, uncoated finish allows visual wear inspection without coating interference
• Straight-cylindrical shank for direct chuck or collet mounting with no adapter required
• Right-hand cutting direction compatible with standard clockwise spindle rotation

Compatibility

Designed as a standard chucking reamer for use in drill presses, milling machines, and CNC machining centers equipped with drill chucks or collet systems accepting a straight-cylindrical shank in the 0.2340-inch diameter class.

Installation Notes

A licensed machinist or trained toolroom operator should install and operate this reamer. Power down and lock out the spindle before mounting or removing the tool from the chuck or collet. Use adequate cutting fluid matched to the workpiece material to extend tool life and maintain hole quality. Do not reverse spindle rotation while the reamer is engaged in the cut, as this can damage the cutting edges.
