Hertel 8272296 Chucking Reamer 57/64 in Hss 8 Flute

Product Description

The HERTEL 8272296 is a straight-flute chucking reamer designed to bring bored or drilled holes to a precise finished diameter. Built from high-speed steel (HSS) with a bright, uncoated finish, this 8-flute reamer cuts right-hand and is sized at 57/64 inch (0.8906 inch decimal) in diameter. The straight-cylindrical shank seats securely in a machine chuck, making it suitable for use in drill presses, lathes, and CNC machining centers. With an overall length of 10 inches and a flute length of 2-5/8 inches, it handles moderate-depth reaming operations where dimensional accuracy and surface finish are the primary goals.

This reamer is intended for metalworking applications where a hole must be opened to a close-tolerance finished size after a preliminary drilling or boring operation. It is a standard production tool used by machinists, tool-and-die workers, and maintenance technicians in job shops, manufacturing facilities, and MRO environments. The 8-flute geometry distributes cutting load evenly, which helps maintain hole roundness and reduces chatter in both ferrous and non-ferrous materials.

Key Features

• 57/64 inch (0.8906 inch) finished reaming diameter
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• 8 straight flutes for balanced cutting load and improved surface finish
• Bright/uncoated finish — suitable for use with cutting fluid as required by the application
• Straight-cylindrical shank for direct chuck mounting in standard machine toolholders
• Right-hand cutting direction — standard orientation for conventional machine reaming

Compatibility

Designed as a standard-production 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.

Installation Notes

Installation and operation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before mounting or removing the reamer from the chuck or collet. Secure the straight-cylindrical shank with sufficient clamping force to prevent slippage under cutting load. Always apply an appropriate cutting fluid for the workpiece material to extend tool life and achieve the target surface finish.
