Hertel 2350627 Chucking Reamer 31/32 in Hss 8 Flute

Product Description

The HERTEL 2350627 is a straight-cylindrical shank chucking reamer designed for precision hole finishing in metal workpieces. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer features 8 spiral flutes in a right-hand cutting direction, delivering clean, accurate bores to a nominal diameter of 31/32 inches (0.9688 inches decimal). At 10 inches overall length with a 2-5/8 inch flute length, it fits standard drill press chucks, CNC machining centers, and manual lathes. It is intended for use by machinists, toolroom technicians, and maintenance professionals who require close-tolerance hole sizing.

This reamer is suited for production and maintenance machining environments where holes must be brought to a precise finished diameter. Typical applications include through-hole and blind-hole finishing in steel, cast iron, aluminum, and similar machinable materials. The straight-cylindrical shank allows direct chuck mounting without the need for a taper adapter, making tool changes straightforward on standard spindles. It is not configured as an over/under size or dowel pin reamer, so it is intended for standard nominal-diameter finishing work.

Key Features

• 31/32 inch nominal diameter (0.9688 inches decimal) for precise hole finishing
• 8 spiral flutes with right-hand cutting direction for smooth material removal and chip evacuation
• HSS construction provides good wear resistance across a range of machinable metals
• Bright, uncoated finish suitable for use with standard cutting fluids
• Straight-cylindrical shank for direct chuck mounting on drill presses, lathes, and machining centers
• 10 inch overall length accommodates reach requirements in typical workholding setups

Compatibility

Designed as a standard chucking reamer for use in drill presses, engine lathes, turret lathes, and CNC machining centers equipped with a chuck or collet capable of accepting a straight-cylindrical shank at 31/32 inch nominal diameter.

Installation Notes

A qualified machinist or toolroom technician should install and operate this reamer. Always ensure the machine spindle is fully stopped and locked out before mounting or removing the tool from the chuck. Secure the shank firmly in a properly sized chuck or collet to prevent slippage under cutting load. Use an appropriate cutting fluid or coolant for the workpiece material to extend tool life and maintain bore quality.
