Hertel 2350205 Chucking Reamer 5/16 in Hss 6 Flute

Product Description

The HERTEL 2350205 is a high-speed steel (HSS) chucking reamer designed for precision hole finishing in metalworking applications. With a 5/16-inch (0.3125 inch decimal) cutting diameter, a 6-inch overall length, and a 1-1/2-inch flute length, this reamer delivers accurate, smooth bores when used in drill presses, lathes, or CNC machining centers. The bright, uncoated HSS construction provides reliable cutting performance across a range of ferrous and non-ferrous materials. Six right-hand spiral flutes promote chip evacuation and consistent surface finish. Machinists and tool-and-die professionals use chucking reamers like this one to bring drilled or bored holes to precise finished dimensions.

This reamer is suited for production and maintenance machining environments where consistent hole tolerances are required. The straight-cylindrical shank allows it to be held in standard drill chucks, collets, or floating reamer holders on manual or CNC equipment. Right-hand cutting direction makes it compatible with conventional clockwise spindle rotation. It is not configured as a dowel pin reamer and is not an over- or under-size specialty reamer, making it a standard-dimension general-purpose tool for everyday reaming operations.

Key Features

• 0.3125 inch (5/16 inch) cutting diameter for precise hole finishing
• 6 right-hand spiral flutes for efficient chip removal and smooth bore finish
• HSS tool material offers good wear resistance across common workpiece materials
• Bright, uncoated finish — no coating concerns for sensitive applications or regrind
• Straight-cylindrical shank fits standard drill chucks and collets
• Right-hand cutting direction for use with standard clockwise spindle rotation

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and CNC machining centers equipped with a drill chuck, collet, or floating reamer holder that accepts a straight-cylindrical shank.

Installation Notes

Chucking reamers should be installed by a qualified machinist following standard toolroom practices. Always power down and lock out the machine spindle before changing tooling. Use a proper floating holder where possible to allow the reamer to self-align with the existing hole and avoid bell-mouthing or chatter. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish quality.
