Hertel 79889242 Chucking Reamer 0.1 in Solid Carbide

Product Description

The HERTEL 79889242 is a solid carbide chucking reamer designed for precision hole finishing in metal and other hard materials. With a reamer diameter of 0.1 inches and a tight tolerance of 0.0000 to 0.0002 inches, this tool delivers consistent, accurate results in production and job-shop environments. The straight flute geometry provides clean cutting action on through-holes, while the bright, uncoated solid carbide construction offers rigidity and wear resistance. The straight cylindrical shank seats securely in standard drill chucks and collet holders. At 2.25 inches overall length with a 0.625-inch flute length, it is sized for light-duty precision reaming operations. Machinists and toolroom technicians are the primary users of this tool.

This reamer is suited for precision reaming of small-diameter holes in ferrous and non-ferrous materials across CNC machining centers, drill presses, and manual lathes. Its 4-flute, right-hand cut configuration makes it appropriate for finishing pre-drilled or bored holes to close tolerances in both production runs and maintenance applications. The compact overall length suits short-reach setups and fixtures where clearance is limited.

Key Features

• Solid carbide construction for rigidity and extended tool life in hard materials
• 0.1-inch diameter with a tolerance of 0.0000 to 0.0002 inches for precise hole sizing
• 4-flute straight geometry for clean, consistent stock removal on through-holes
• Right-hand cutting direction compatible with standard machine spindle rotation
• Bright, uncoated finish suitable for use with cutting fluids across a range of materials
• Straight cylindrical shank for direct mounting in drill chucks or collet holders

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks and collet holders accepting a 0.1-inch straight cylindrical shank.

Installation Notes

This tool is installed and operated by machinists and toolroom technicians. Power down the machine and confirm the spindle is fully stopped before mounting or removing the reamer. Seat the shank fully in the chuck or collet and verify runout before cutting. Always use appropriate cutting fluid for the workpiece material to extend tool life and maintain hole-finish quality.
