Hertel 79888764 Chucking Reamer 0.0375 in Solid Carbide

Product Description

The HERTEL 79888764 is a solid carbide chucking reamer designed for precision hole finishing in tight-tolerance machining applications. With a reamer diameter of 0.0375 inches and a diameter tolerance held to 0.0000 to 0.0002 inches, this tool delivers accurate, repeatable results in production and job-shop environments. The 4-flute straight flute geometry provides smooth cutting action, while the bright uncoated finish suits a wide range of workpiece materials. At 1.5 inches overall length with a 0.25-inch flute length, this is a compact tool built for small-bore reaming where precision matters. Machinists and tool operators install this reamer in CNC machining centers, drill presses, and manual lathes equipped with a compatible chuck.

This chucking reamer is suited for finishing pre-drilled or bored holes to close dimensional tolerances in metal components. The straight-cylindrical shank allows direct chucking in standard collets or drill chucks without additional adapters. Right-hand cutting direction is standard for conventional spindle rotation. Applications include aerospace, automotive, and general precision machining where small-diameter hole finishing is required. The compact overall length makes it well-suited for shallow-bore work or use in confined setups where tool stick-out must be minimized.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision reaming
• 0.0375-inch diameter with tolerance of 0.0000 to 0.0002 inches for close-tolerance hole finishing
• 4-flute straight flute design for smooth, consistent cutting action
• Bright uncoated finish compatible with a broad range of workpiece materials
• Straight-cylindrical shank for direct chucking in collets or standard drill chucks
• Right-hand cut with conventional spindle rotation

Compatibility

Designed as a standard chucking reamer for use in CNC machining centers, drill presses, and manual lathes equipped with collet chucks or drill chucks accepting a straight-cylindrical shank.

Installation Notes

Installation is performed by qualified machinists. Secure the straight shank firmly in a collet or drill chuck to minimize runout before operation. Always pre-drill or bore the hole to the appropriate undersize before reaming to achieve the specified tolerance. Ensure spindle speed and feed rate are appropriate for the workpiece material and tool diameter per standard machining practice.
