Hertel 79890695 Chucking Reamer Size 34 Solid Carbide

Product Description

The HERTEL 79890695 is a solid carbide chucking reamer in wire size 34, designed to finish-ream holes to a precise diameter of 0.1110 inches. Built from solid carbide with a bright, uncoated finish, this reamer delivers tight diameter tolerances of 0.0000 to 0.0002 inches, making it well-suited for precision hole finishing in hard or abrasive materials. The straight-cylindrical shank accepts standard chuck toolholding, and the four straight flutes cut right-hand on a 2.25-inch overall length tool. Machinists and tool-and-die professionals use this reamer where dimensional accuracy is critical and carbide rigidity is preferred over high-speed steel.

This reamer is applied in precision machining operations where wire-size holes in the 0.1000 to 0.1499 inch diameter range require a clean, accurate finish. Typical applications include production machining of close-tolerance bores in metal components, fixture and die work, and general machine-shop operations. The straight flute geometry suits non-interrupted, through-hole reaming in ferrous and non-ferrous metals. The 0.625-inch flute length accommodates shallow to moderate depth holes at this diameter range.

Key Features

• Solid carbide construction for rigidity and wear resistance in abrasive materials
• Wire size 34 diameter at 0.1110 inches with a tolerance of 0.0000 to 0.0002 inches
• Four straight flutes with right-hand cutting direction
• Straight-cylindrical shank for standard chuck or collet toolholding
• Bright, uncoated finish suitable for a wide range of workpiece materials
• Overall length of 2.25 inches with a 0.625-inch flute length

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill presses, CNC machining centers, or manual lathes and mills equipped with a chuck or collet capable of accepting a straight-cylindrical shank at this diameter range.

Installation Notes

Chucking reamers should be installed by a qualified machinist following proper toolholding procedures for the machine in use. Ensure the machine spindle is fully stopped and locked out before changing tooling. Use the correct cutting fluid or lubricant recommended for the workpiece material to extend tool life and maintain bore finish quality. Do not use a reamer to remove excessive stock; pre-drill or bore the hole to within the appropriate allowance before reaming.
