Hertel 2292035 Chucking Reamer Letter C Hss 6 in Oal

Product Description

The HERTEL 2292035 is a straight-flute chucking reamer designed to finish-ream holes to a precise Letter C diameter of 0.2420 inches. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing in ferrous and non-ferrous materials across production and maintenance machining environments. The straight-cylindrical shank seats directly in drill chucks or collet holders, making setup fast and repeatable. With a 6-inch overall length and a 1-1/2-inch flute length, it is suited for through-hole and shallow blind-hole reaming where tight tolerances are required. Right-hand cutting direction follows standard lathe and drill press rotation.

This reamer is intended for machine-tool use — lathes, drill presses, CNC machining centers, and manual knee mills — wherever a Letter C finish-reamed hole is called for. Typical applications include fixture and jig work, close-tolerance pin and dowel hole preparation, and general production reaming in shops handling light to medium stock removal. It is not configured as a dowel pin reamer or an over/under-size reamer, making it a standard straight-tolerance tool for general hole-finishing operations.

Key Features

• Letter C diameter (0.2420 inches) for precise finish reaming to standard letter-size tolerances
• HSS construction provides toughness and wear resistance across a range of workpiece materials
• Bright/uncoated finish — suitable for use with cutting fluid in standard machining operations
• Straight-cylindrical shank for direct chucking in drill chucks or collet tool holders
• Right-hand cut, straight flutes for clean, consistent stock removal with minimal chatter
• 6-inch OAL with 1-1/2-inch flute length balances reach and rigidity in typical setups

Compatibility

Designed as a standard letter-size chucking reamer compatible with any drill chuck or collet holder accepting a straight-cylindrical shank in the corresponding diameter range.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with reaming operations. Power down and lock out the machine before mounting or removing the reamer from the chuck or collet. Use an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Pre-drill the hole to the correct undersize before reaming — do not use a chucking reamer to remove excessive stock.
