Hertel 72011851 Chucking Reamer 0.1185 in Hss Straight

Product Description

The HERTEL 72011851 is a chucking reamer designed for precision hole finishing in machine tool applications. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer produces accurate, smooth bores in a range of materials. The straight-cylindrical shank seats securely in standard chucks for reliable concentricity during operation. With a 0.1185-inch cutting diameter, a 0.875-inch flute length, and a 3.5-inch overall length, it is sized for small-diameter finish reaming in production and maintenance machining environments. Machinists and toolroom technicians working on CNC machines, drill presses, or manual lathes are the primary users of this tool.

This chucking reamer is suited for small-diameter through-hole and blind-hole finishing operations in metalworking shops, maintenance facilities, and production environments. The straight flute geometry is well matched to softer and medium-hardness materials where chip evacuation is straightforward. The right-hand cutting direction is standard for conventional clockwise-spindle machines. It falls within the 0.1000 to 0.1499 decimal-inch reamer diameter range, making it applicable wherever a close-tolerance 0.1185-inch finish bore is required.

Key Features

• 0.1185-inch cutting diameter for precise small-bore finishing
• HSS construction provides durability across a broad range of workpiece materials
• Straight flute design promotes clean chip flow in through-hole applications
• Right-hand cutting direction compatible with standard clockwise-spindle machines
• Straight-cylindrical shank for secure, concentric chuck mounting
• Bright, uncoated finish — no coating thickness to account for in tolerance calculations

Compatibility

Designed as a standard chucking reamer for use in any machine spindle or drill press chuck accepting a straight-cylindrical shank of the appropriate diameter range.

Installation Notes

Installation and use of this reamer should be performed by a qualified machinist. Ensure the machine spindle is fully stopped and the tool is securely seated and tightened in the chuck before starting the spindle. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore quality. Do not use this reamer as a drill — it is a finishing tool and requires a pre-drilled or bored hole close to final size before reaming.
