Hertel 2350197 Chucking Reamer 19/64 in Hss 6 Flute

Product Description

The HERTEL 2350197 is a straight-shank chucking reamer designed to finish-ream drilled holes to a precise 19/64 inch (0.2969 inch decimal) diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it features 6 right-hand spiral flutes that promote smooth cutting action and efficient chip evacuation. The tool measures 6 inches in overall length with a 1.5 inch flute length, making it well-suited for moderate-depth reaming operations in a standard drill chuck or lathe. Machinists, tool-and-die workers, and maintenance technicians use this reamer to bring bored or drilled holes to close-tolerance final dimensions.

This chucking reamer is used in general machining, maintenance repair, and fabrication environments where a straight-cylindrical shank is required for direct chuck mounting. Its right-hand cutting direction suits standard CNC machining centers, manual lathes, and drill presses. The 19/64 inch diameter targets hole finishing applications in the 0.2500 to 0.2999 inch decimal range, which covers common fastener clearance and dowel pin fit scenarios across metal, plastics, and composite materials.

Key Features

• 19/64 inch (0.2969 inch decimal) finished diameter for close-tolerance hole sizing
• High-speed steel (HSS) construction for durability across a broad range of workpiece materials
• 6 right-hand spiral flutes for smooth cutting action and effective chip removal
• Bright, uncoated finish suitable for general-purpose reaming without added surface treatment
• Straight-cylindrical shank for direct mounting in standard drill chucks or collets
• 6 inch overall length with 1.5 inch flute length for moderate-depth applications

Compatibility

Designed as a general-purpose chucking reamer compatible with standard drill chucks, collet holders, and lathe tailstocks that accept a straight-cylindrical shank in the applicable diameter range.

Installation Notes

This tool is installed and operated by machinists or maintenance technicians familiar with reaming procedures. Always secure the workpiece and ensure the reamer is running true before engaging the cut. Use appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Never reverse the cutting direction while the flutes are engaged in the hole, as this can damage the cutting edges.
