Hertel 72033459 Chucking Reamer 0.3450 in Hss 6 Flute

Product Description

The HERTEL 72033459 is a high-speed steel (HSS) chucking reamer designed for precision hole finishing in metalworking applications. With a reamer diameter of 0.3450 inches and an overall length of 6 inches, this tool delivers accurate, repeatable bore sizing on a variety of workpiece materials. The straight-cylindrical shank allows secure mounting in standard drill chucks or collet-style holders. The bright, uncoated HSS construction provides a reliable cutting edge for general-purpose reaming without coating-related dimensional concerns. Machinists and tool-and-die professionals rely on this style of reamer when tight bore tolerances are required after drilling.

This chucking reamer is suited for machine shop environments, production floors, and maintenance operations where drilled holes require final sizing to close tolerance. The 6-flute straight configuration promotes smooth stock removal and good surface finish in through-holes and blind holes alike. The right-hand cutting direction is standard for conventional CNC and manual lathe or drill press setups. A 1.5-inch flute length supports engagement in shallow-to-moderate depth bores at this diameter range.

Key Features

• 0.3450 inch reamer diameter for precision bore finishing in the 0.3000-0.3499 inch diameter range
• 6-inch overall length with 1.5-inch flute length for controlled depth engagement
• 6-flute straight configuration for smooth cutting action and consistent surface finish
• HSS tool material provides durability across a broad range of workpiece materials
• Bright, uncoated finish maintains dimensional accuracy without coating build-up
• Right-hand cutting direction compatible with standard machine setups

Compatibility

Designed as a general-purpose chucking reamer for use in standard drill chucks, collet holders, and floating reamer holders on CNC machining centers, knee mills, lathes, and drill presses where a straight-cylindrical shank is accepted.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with reaming operations and machine tool safety. Secure the straight-cylindrical shank fully in the chuck or collet before operation and confirm runout is within tolerance before cutting. Always reduce spindle speed relative to drilling and apply appropriate cutting fluid to extend tool life and improve surface finish. Power down and lock out the machine before changing or adjusting the reamer.
