Hertel 2290013 Chucking Reamer 1/64 in Hss Straight Shank

Product Description

The HERTEL 2290013 is a high-speed steel (HSS) chucking reamer designed to finish-ream precision holes to tight tolerances in metalworking applications. With a 1/64 inch (0.0156 inch decimal) cutting diameter, this reamer is engineered for very small-bore finishing passes where dimensional accuracy and surface finish are critical. The straight flute geometry and bright, uncoated HSS construction make it suitable for general-purpose reaming in a wide range of ferrous and non-ferrous materials. Machinists and tool-and-die professionals install this tool in CNC lathes, drill presses, or manual machines using a standard chuck or collet holder.

This reamer is intended for small-diameter finish reaming operations in machine shops, tool rooms, and production environments. The straight-cylindrical shank allows secure clamping in a wide variety of chucks and collets without requiring a specialized holder. Right-hand cutting direction is standard for conventional clockwise spindle rotation. At 3/4 inch overall length with a 3/8 inch flute length, this tool is sized for shallow, precision bore finishing in small workpieces or thin-section components.

Key Features

• 1/64 inch (0.0156 inch) cutting diameter for very small-bore finish reaming
• HSS tool material provides good wear resistance across a broad range of workpiece materials
• Straight flute design for smooth cutting action and chip clearance
• Bright, uncoated finish — no coating buildup affecting final bore diameter
• Straight-cylindrical shank for secure clamping in standard chucks and collets
• Right-hand cutting direction compatible with standard clockwise spindle rotation

Compatibility

Designed as an OEM-style chucking reamer suitable for use in CNC lathes, drill presses, and manual machines equipped with standard chucks or collets accepting a straight-cylindrical shank.

Installation Notes

Installation is performed by machining professionals. Secure the straight-cylindrical shank firmly in a properly sized chuck or collet before use, and verify runout is within acceptable limits for the bore tolerance required. Power down the machine and lock out the spindle before changing or inspecting the tool. Do not use this reamer as a drill; always pre-drill or pre-bore the hole to near-finished size before reaming.
