Hertel 83247122 Chucking Reamer 8.5 Mm Solid Carbide

Product Description

The HERTEL 83247122 is a solid carbide chucking reamer designed for precision hole finishing in machine shop and production environments. Built with a straight flute geometry and a straight cylindrical shank, this reamer produces accurate, close-tolerance bores with a nominal diameter of 8.5 mm (0.3346 inches). The diameter tolerance holds between 0.0000 and 0.0003 inches, making it suitable for applications where hole size consistency is critical. The bright, uncoated carbide construction provides rigidity and wear resistance across a range of work materials. Machinists and toolroom technicians rely on this style of reamer for repeatable sizing on CNC machining centers and manual lathes alike.

This chucking reamer is intended for use in general machining operations requiring a finished bore in the 8.00 to 9.00 mm diameter range. It fits standard machine spindles and chucks that accept a straight cylindrical shank. Typical applications include production reaming of steel, cast iron, aluminum, and non-ferrous alloys where a precise, finished bore is required after drilling. The six-flute configuration distributes cutting load evenly and supports a smooth surface finish in the reamed hole. Right-hand cutting direction means it runs with standard clockwise spindle rotation.

Key Features

• Solid carbide construction for rigidity and extended tool life in hard or abrasive materials
• 8.5 mm nominal diameter with a tolerance of 0.0000 to 0.0003 inches for tight bore sizing
• Six straight flutes for even cutting load distribution and consistent surface finish
• Bright, uncoated finish suitable for a wide range of base work materials
• Straight cylindrical shank for direct chuck mounting on lathes and machining centers
• Right-hand cut with standard clockwise spindle rotation

Compatibility

Designed as a standard chucking reamer for machine spindles and chucks accepting a straight cylindrical shank in the 8.00 to 9.00 mm reamer diameter range.

Installation Notes

Installation and use should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool is securely seated and clamped in the chuck before initiating a cut. Use appropriate cutting fluid for the work material to promote tool life and surface finish quality. Never attempt to adjust or remove the reamer while the spindle is in motion.
