Hertel 2297158 Chucking Reamer 11.50mm Hss 6-flute

Product Description

The HERTEL 2297158 is a straight-flute chucking reamer designed to finish-ream holes to a precise 11.50mm (0.4528 inch) diameter. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers clean, accurate bores in a wide range of ferrous and non-ferrous workpiece materials. The 7-inch overall length and 1.75-inch flute length suit standard machine tool setups, while the straight-cylindrical shank seats securely in drill chucks and collet holders. Right-hand cutting direction matches conventional machine spindle rotation. This tool is used by machinists, toolroom technicians, and maintenance professionals requiring tight-tolerance hole finishing.

This reamer is suited for precision hole finishing operations on manual mills, CNC machining centers, drill presses, and lathes where a consistent, smooth bore is required. The 6-flute configuration distributes cutting load evenly, reducing chatter and improving surface finish in through-holes and blind-hole applications. It covers the 0.4000 to 0.4999 decimal-inch diameter range class, making it a practical stock item for shops working to metric and fractional print tolerances in that size band.

Key Features

• 11.50mm (0.4528 inch) reamer diameter for precise metric hole sizing
• 6 straight flutes for even load distribution and reduced chatter
• HSS tool material provides toughness across a broad range of materials
• Bright, uncoated finish suitable for use with cutting fluids
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Right-hand cutting direction for conventional spindle rotation

Compatibility

Designed as a standard chucking reamer for use in any machine tool equipped with a drill chuck or collet holder accepting a straight-cylindrical shank in the 0.45-inch diameter class.

Installation Notes

Installation and use of this reamer should be performed by a qualified machinist or toolroom technician. Always power down and lock out the machine spindle before loading or removing the tool from the chuck or collet. Use appropriate cutting fluid for the workpiece material to extend tool life and improve bore finish. Ensure the workpiece is rigidly fixtured before beginning the reaming pass to prevent tool deflection and maintain dimensional accuracy.
