Hertel 2292076 Chucking Reamer Letter G Hss 6 Flute

Product Description

The HERTEL 2292076 is a straight-flute chucking reamer designed to finish-ream holes to a Letter G diameter of 0.2610 inches. Machined from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing in through-holes and blind holes across a wide range of ferrous and non-ferrous workpieces. The straight-cylindrical shank mounts directly into a drill chuck or collet for fast, repeatable tool changes. At 6 inches overall length with a 1.5-inch flute length and six right-hand cutting flutes, this reamer is suited for production and maintenance machining operations where close-tolerance hole finishing is required.

This reamer is used in general machining environments including job shops, toolrooms, and maintenance repair operations. It is sized for Letter G holes, commonly needed when fitting dowel pins, bushings, or precision-fit fasteners. The 6-inch OAL provides adequate reach for standard workpiece thicknesses while keeping the tool rigid. It is appropriate for use in manual drill presses, CNC machining centers, and turret lathes where a straight-shank reamer is called for. Machinists and tool-and-die technicians are the primary installers.

Key Features

• Letter G diameter: 0.2610 inches — suited for close-tolerance hole finishing
• Six straight right-hand flutes for smooth chip evacuation and consistent surface finish
• High-speed steel construction provides durability across a broad range of workpiece materials
• Bright, uncoated finish — no coating buildup that can affect dimensional accuracy
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• 6-inch OAL with 1.5-inch flute length balances reach and rigidity

Compatibility

Designed as an OEM-style chucking reamer for use in any machine tool accepting a straight-cylindrical shank at Letter G diameter sizing.

Installation Notes

Chucking reamers are installed and operated by machinists. Ensure the machine spindle is fully stopped and the workpiece is securely fixtured before tool changes. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain dimensional accuracy. Do not use a reamer to open undersized holes by more than a few thousandths of an inch — pre-drill or bore the hole close to final size before reaming.
