Hertel 53342408 Chucking Reamer 0.8745 in Hss 8 Flute

Product Description

The HERTEL 53342408 is a high-speed steel (HSS) chucking reamer designed for precision hole finishing in metal machining applications. With a 0.8745-inch diameter and 8 straight flutes, this reamer delivers accurate, smooth-bore results in through-holes and blind holes. The straight-cylindrical shank seats securely in standard drill chucks and collet holders. A bright, uncoated finish keeps the tool ready for general-purpose reaming where coolant compatibility and visual inspection of the cutting edges are routine requirements. Machinists and toolroom technicians use this reamer where tight diameter tolerances are required after drilling or boring.

This chucking reamer is suited for manual machining centers, CNC lathes, drill presses, and milling machines performing finishing passes on steel, cast iron, aluminum, and similar machinable materials. The 2-5/8-inch flute length provides adequate chip clearance for moderate-depth reaming operations. Right-hand cutting direction matches standard spindle rotation. The 10-inch overall length gives extra reach for fixtures or setups where the workpiece is recessed or held in a deep vise.

Key Features

• 0.8745-inch finished diameter for precision bore sizing
• 8 straight flutes for smooth chip evacuation and consistent surface finish
• Right-hand cutting direction for standard spindle compatibility
• Straight-cylindrical shank fits standard drill chucks and collet holders
• Bright, uncoated HSS construction for general-purpose reaming across common metals
• 10-inch overall length provides extended reach capability

Compatibility

Designed as a general-purpose chucking reamer compatible with any machine spindle or chuck accepting a straight-cylindrical shank in the applicable diameter range.

Installation Notes

This reamer is installed and operated by machinists or toolroom technicians. Power down and lock out the machine spindle before inserting or removing the reamer from the chuck or collet. Ensure the shank is fully seated and the chuck is tightened to the machine manufacturer's specification before operation. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain surface finish quality.
