Hertel 2410363 Chucking Reamer 9/16 in 6 Flute Hss

Product Description

The HERTEL 2410363 is a 6-flute high-speed steel (HSS) chucking reamer designed to finish-ream drilled or bored holes to precise dimensional tolerances. Built on a straight-cylindrical shank, this reamer seats securely in drill chucks, collet chucks, and floating holders. The spiral flute geometry with a left-hand spiral and right-hand cutting direction improves chip evacuation and reduces chatter on through-holes. At 9/16 inch (0.5625 inch) diameter with a 2-inch flute length and 8-inch overall length, it handles typical depth requirements in both manual and CNC machine tool operations. The bright, uncoated finish is standard for HSS reamers used in general-purpose ferrous and non-ferrous materials. Machinists and tool-and-die tradespeople are the primary users.

This chucking reamer is suited for finishing operations on through-holes and blind holes in machine shop, maintenance, and production environments. It works in vertical mills, drill presses, lathes, and CNC machining centers where a floating reamer holder or rigid setup is used to guide the tool. The 9/16 inch diameter range is common in structural, mechanical assembly, and general metalworking applications where a finish-reamed hole is required for close-tolerance pin, shaft, or fastener fits.

Key Features

• 9/16 inch (0.5625 inch) diameter for close-tolerance hole finishing
• 6-flute design distributes cutting load and improves surface finish
• Left-hand spiral flutes with right-hand cutting direction for improved chip flow
• High-speed steel (HSS) construction for durability across ferrous and non-ferrous materials
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Bright uncoated finish — suitable for re-sharpening in tool rooms

Compatibility

Designed as a standard straight-shank chucking reamer for use in drill presses, vertical mills, lathes, and CNC machining centers equipped with drill chucks or collet holders accepting a straight-cylindrical shank.

Installation Notes

Chucking reamers are installed by qualified machinists or tooling technicians. Power down and lock out the machine before inserting or removing the reamer from its holder. Use a floating reamer holder where possible to compensate for minor spindle misalignment and avoid bell-mouthing the hole. Always apply appropriate cutting fluid for the workpiece material, and never run a reamer in reverse as it will dull the cutting edges.
