Hertel 79890208 Chucking Reamer 5/32 in Solid Carbide

Product Description

The HERTEL 79890208 is a solid carbide chucking reamer designed for precision hole finishing in machine shop and production environments. Built with a straight flute geometry and a straight cylindrical shank, it delivers consistent, tight-tolerance bores in a wide range of workpiece materials. The bright uncoated carbide construction provides rigidity and wear resistance suited for close-tolerance applications. At 0.1562 inches nominal diameter with a reamer diameter tolerance of 0.0000 to 0.0002 inches, this tool holds sizing accuracy that meets demanding finish-bore requirements. Machinists and tool-room technicians reach for this style of reamer when hole quality and dimensional repeatability are the priority.

This chucking reamer is intended for use in drill presses, CNC machining centers, turret lathes, and similar machine tool setups where the reamer is held in a chuck or collet. The 4-flute, right-hand-cut configuration suits through-hole and blind-hole finishing passes at controlled feed and speed. With an overall length of 2.5 inches and a flute length of 0.75 inches, it fits compact tooling setups and short-reach applications common in precision part production and repair operations.

Key Features

• Solid carbide construction for rigidity and extended tool life in abrasive or hard workpiece materials
• 4-flute straight flute design for smooth, consistent material removal on finish-bore passes
• Diameter tolerance of 0.0000 to 0.0002 inches ensures tight, repeatable sizing
• Bright uncoated finish compatible with a wide range of cutting fluids and workpiece materials
• Straight cylindrical shank for secure seating in standard chucks and collets
• Right-hand cutting direction, standard for conventional machine reaming operations

Compatibility

Designed as a standard chucking reamer for use in any machine tool that accepts a straight cylindrical shank of 5/32 inch diameter, including drill presses, CNC mills, turret lathes, and machining centers equipped with appropriate chuck or collet toolholding.

Installation Notes

Chucking reamers are installed and serviced by machinists and tool-room technicians. Always ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the straight shank fully and evenly in the chuck or collet and verify runout before beginning a cut. Use appropriate cutting fluid for the workpiece material, and never use a chucking reamer to remove more stock than the tool geometry is rated to handle — pre-drill or bore to the correct pre-ream allowance before use.
