Hertel 79888848 Chucking Reamer 0.048 in Solid Carbide

Product Description

The HERTEL 79888848 is a solid carbide chucking reamer designed for precision hole finishing in close-tolerance machining applications. With a reamer diameter of 0.048 inches and a diameter tolerance of 0.0000 to 0.0002 inches, this tool delivers consistent bore accuracy in small-diameter work. The straight flute geometry and right-hand cutting direction suit it for use in standard CNC machining centers, drill presses, and manual lathes. At 1.5 inches overall length with a 0.375-inch flute length, it fits tight-access setups. The bright, uncoated finish is typical for carbide reamers used across a range of ferrous and non-ferrous materials.

This chucking reamer is suited for production and job-shop environments where small-diameter bore finishing is required. The straight-cylindrical shank seats directly in standard collets and drill chucks without adapters, making it a straightforward drop-in for most setups. Machinists and tool-and-die technicians working on precision components, instrumentation parts, and small mechanical assemblies will find this size range commonly required for pin holes, dowel bores, and bearing seats at sub-0.05-inch diameters.

Key Features

• Solid carbide construction for rigidity and wear resistance in small-diameter reaming
• 0.048-inch reamer diameter with a tight tolerance of 0.0000 to 0.0002 inches for precision bore finishing
• Straight flute design with 4 flutes for smooth chip flow
• Right-hand cutting direction compatible with standard spindle rotation
• Straight-cylindrical shank seats in collets and drill chucks without adapters
• Bright, uncoated finish suitable for a range of workpiece materials

Compatibility

Designed as an OEM-style solid carbide chucking reamer for use in CNC machining centers, manual lathes, and drill presses equipped with collet or drill-chuck toolholding accepting a straight-cylindrical shank.

Installation Notes

Installation is performed by qualified machinists familiar with precision reaming operations. Secure the straight shank in a collet or drill chuck with adequate runout control before use, as excessive runout will compromise bore tolerance. Always ream to a pre-drilled or bored pilot hole sized appropriately for the stock allowance; do not use this tool as a primary drilling tool. Apply appropriate cutting fluid for the workpiece material and ensure spindle speed and feed rate match the tool diameter and material requirements per standard machining practice.
