Hertel 72018955 Chucking Reamer 0.1895 in Hss 6 Flute

Product Description

The HERTEL 72018955 is a high-speed steel (HSS) chucking reamer designed for precision hole finishing in metal workpieces. With a cutting diameter of 0.1895 inches and a straight-cylindrical shank, this reamer mounts directly in a drill chuck or collet chuck on a drill press, lathe, or machining center. The bright uncoated HSS construction handles a wide range of ferrous and non-ferrous materials. Six straight flutes provide smooth, consistent stock removal and accurate final bore sizing. The 1.125-inch flute length suits typical through-hole and shallow blind-hole finishing operations. Machinists and toolroom technicians rely on this style of reamer to bring drilled or bored holes to close-tolerance finished dimensions.

This chucking reamer is suited for general machining environments including job shops, maintenance and repair operations, and production toolrooms. It is used when a drilled hole must be finished to a precise diameter for press fits, slip fits, or close-clearance pin and dowel locations. The right-hand cutting direction is standard for conventional machine spindle rotation. Typical applications involve finishing holes in steel, cast iron, aluminum, and brass workpieces on manual or CNC equipment.

Key Features

• 0.1895-inch cutting diameter for close-tolerance hole finishing
• HSS construction with bright uncoated finish suitable for a wide range of workpiece materials
• 6 straight flutes for smooth cutting action and consistent bore geometry
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight-cylindrical shank for direct chucking in standard drill chucks or collet holders
• 4.5-inch overall length provides adequate reach for typical through-hole applications

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks, collet chucks, and floating reamer holders on drill presses, lathes, and machining centers accepting a straight-cylindrical shank of this diameter range.

Installation Notes

Installation and operation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before mounting or removing the reamer from the chuck or collet. Ensure the shank is fully seated and the chuck or collet is properly tightened before commencing the cut. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality.
