Hertel 79890125 Chucking Reamer 0.501 in Solid Carbide

Product Description

The HERTEL 79890125 is a solid carbide chucking reamer designed for precision hole finishing in machined components. With a reamer diameter of 0.501 inches, this is an over-size reamer rated at 0.5010 inches, making it suitable for applications where a controlled interference or press fit is required. The 4-inch overall length and 1-1/2-inch straight flute provide consistent stock removal and surface finish in through and blind bores. With six flutes and a right-hand cutting direction, it delivers smooth, repeatable cuts. Machinists and tool-room operators use this style of reamer in CNC machining centers and drill presses where tight bore tolerances are critical.

This chucking reamer is suited for use in metalworking environments including job shops, production machining, and precision fabrication. The straight cylindrical shank allows direct clamping in standard drill chucks or collet-style toolholders. The bright, uncoated finish makes it appropriate for a range of base metals where coating interaction is a concern. It is sized as an over-size reamer at 0.5010 inches, intended for applications requiring slightly enlarged bores relative to the nominal 0.500-inch dimension.

Key Features

• Solid carbide construction for extended tool life in hard and abrasive materials
• 0.5010-inch over-size diameter for controlled bore expansion beyond nominal 0.500 inch
• Six straight flutes for smooth, consistent surface finish
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight cylindrical shank for use in drill chucks and collet holders
• Bright, uncoated finish suitable for a broad range of workpiece materials

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill press, lathe, or CNC machining center setups accepting a straight cylindrical shank toolholder.

Installation Notes

Installation and use should be performed by qualified machinists familiar with reaming operations and machine tool safety. Always confirm spindle speed and feed rate are appropriate for the workpiece material and carbide tooling before starting the cut. Secure the shank fully in the toolholder and verify runout before engaging the workpiece. Never run a reamer in reverse, as this will damage the cutting edges.
