Hertel 83246710 Chucking Reamer 0.1865 in Solid Carbide

Product Description

The HERTEL 83246710 is a solid carbide chucking reamer designed for precision hole finishing in machine tool applications. Built to an undersize diameter of 0.1865 inches with a tolerance of 0.0000 to 0.0002 inches, it delivers tight, repeatable bore geometry in a single pass. The straight flute geometry suits most general-purpose reaming operations in through-holes. With a 2-3/4 inch overall length and a 7/8 inch flute length, this reamer fits standard drill press and CNC machining center setups. Machinists, tool and die makers, and production shop operators are the primary users of this tool.

This reamer is appropriate for finishing holes in the 0.1500 to 0.1999 inch diameter range where close tolerances and smooth surface finish are required. The undersize designation makes it well-suited for applications requiring light material removal after drilling, such as preparing bores for press-fit pins or precision shaft seats. Its bright, uncoated finish is suitable for a range of ferrous and non-ferrous workpiece materials in both manual and CNC-driven machine setups.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision reaming
• Undersize diameter of 0.1865 inches with a tight tolerance of 0.0000 to 0.0002 inches
• 4-flute straight flute design for consistent chip evacuation in through-hole applications
• Straight cylindrical shank for direct chuck or collet mounting
• Right-hand cutting direction for standard spindle rotation
• Bright, uncoated finish — no coating buildup to affect dimensional accuracy

Compatibility

Designed as an OEM-style chucking reamer for use in drill presses, milling machines, and CNC machining centers accepting straight cylindrical shank tooling in the applicable collet or chuck size range.

Installation Notes

Chucking reamers are installed by licensed machinists or skilled shop technicians into a collet, drill chuck, or floating reamer holder. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Use the correct collet bore size for a secure, concentric grip on the straight shank. Always run reamers at appropriate speed and feed for the workpiece material — excessive feed rate or insufficient coolant flow can cause tool deflection or premature wear.
