Hertel 7029028 Chucking Reamer 0.9980 in Hss 8 Flute

Product Description

The HERTEL 7029028 is a straight-flute chucking reamer designed for precision hole finishing in metalworking applications. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent bore accuracy in a range of ferrous and non-ferrous materials. The reamer measures 0.9980 inches in diameter with an overall length of 10.5 inches and a flute length of 2.75 inches. Eight straight flutes and a right-hand cutting direction provide smooth material removal and accurate sizing. The straight-cylindrical shank allows secure chuck mounting in drill presses, lathes, and machining centers. Machinists and tool-and-die professionals are the primary installers of this type of precision reamer.

This chucking reamer is suited for production and job-shop environments where close-tolerance hole finishing is required. It is appropriate for through-hole and blind-hole reaming operations where a final bore diameter of 0.9980 inches is specified. The 10.5-inch overall length accommodates reach requirements in deeper workpieces. The HSS construction makes it a practical choice for general-purpose reaming at moderate cutting speeds, particularly in applications where carbide tooling is not required. It is sold and packaged as a single unit.

Key Features

• 0.9980 inch finished bore diameter for close-tolerance hole sizing
• High-speed steel (HSS) construction provides durability across general-purpose metalworking applications
• 8 straight flutes with right-hand cutting direction for smooth, consistent material removal
• Straight-cylindrical shank for reliable chuck retention on standard machine spindles
• Bright, uncoated finish — no coating variables affecting final bore dimension
• 10.5 inch overall length with 2.75 inch flute length for reach in deeper bores

Compatibility

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

Installation Notes

Chucking reamers are installed and operated by machinists following standard machine tool safety procedures. Ensure the machine spindle and chuck are fully stopped and de-energized before mounting or removing the reamer. Secure the straight-cylindrical shank firmly in a drill chuck or collet to prevent runout, which directly affects bore accuracy. Use appropriate cutting fluid for the workpiece material to extend tool life and achieve the specified finish.
