Harvey Tool RSB1735-C3 Chucking Reamer 0.1735 in Carbide

Product Description

The HARVEY TOOL RSB1735-C3 is a solid carbide chucking reamer designed for precision holemaking in tight-tolerance applications. Built to a 0.1735-inch diameter with a diameter tolerance of +0.0002 to 0.0000 inches, this reamer holds close final-hole dimensions on the positive side without cutting under. The AlTiN coating improves wear resistance and tool life in harder workpiece materials. With 4 straight flutes and right-hand cutting direction, it produces a clean, accurate bore in a single pass. Overall length is 4 inches, flute length is 1 inch, and the straight-cylindrical shank measures 0.1875 inches (3/16 inch) in diameter. Machinists and tool-and-die professionals install this part in CNC machining centers or drill presses requiring consistent miniature bore sizing.

This reamer belongs to the HARVEY TOOL Miniature Reamers series, purpose-built for small-diameter precision work in the 0.1500 to 0.1999-inch diameter range. Typical applications include reaming pilot holes, dowel pin holes, and precision bores in ferrous and non-ferrous metals, tool steels, and hardened materials where the AlTiN coating provides thermal and abrasion resistance. The short 1-inch flute length suits shallow-to-moderate depth holes common in instrument, medical device, and mold-and-die machining. Coolant-through capability is not featured on this model, so external coolant or mist lubrication is recommended during operation.

Key Features

• 0.1735-inch finished bore diameter with +0.0002 to 0.0000-inch tolerance for precise, repeatable sizing
• Solid carbide construction for rigidity and extended tool life in demanding materials
• AlTiN coating increases hardness and heat resistance, extending performance in dry or semi-dry cutting conditions
• 4 straight flutes with right-hand cutting direction for clean bore finish
• Straight-cylindrical shank (0.1875 inches) for compatibility with standard collet chucks and drill chucks
• Part of the Miniature Reamers series, covering diameters from 0.1500 to 0.1999 inches

Compatibility

Designed for use in CNC machining centers, drill presses, and other holemaking equipment accepting a 3/16-inch (0.1875-inch) straight-cylindrical shank. Suited for miniature bore finishing operations within the 0.1500 to 0.1999-inch diameter range as specified by the HARVEY TOOL Miniature Reamers series.

Installation Notes

This reamer is installed and operated by machinists and toolroom professionals. Secure the straight shank firmly in a precision collet or drill chuck rated for the required runout tolerance before use. Verify spindle runout is within acceptable limits prior to reaming, as excessive runout will compromise hole tolerance and shorten tool life. External cutting fluid or mist lubrication is recommended since this model does not feature coolant-through capability.
