Hertel 45676269 Chucking Reamer 0.343 in Solid Carbide

Product Description

The HERTEL 45676269 is a solid carbide chucking reamer designed for precision hole finishing in machining applications. With a reamer diameter of 0.343 inches and a 6-flute straight flute geometry, it delivers consistent bore sizing and smooth surface finishes in a single pass. The straight shank makes it compatible with standard chucks and collets on CNC machining centers, drill presses, and manual lathes. The bright polished finish reduces friction and aids chip evacuation. At 3.5 inches overall length with a 1.25-inch flute length, this reamer is well suited for moderate-depth through and blind holes. It is installed by machinists and tool and die professionals working to close dimensional tolerances.

This chucking reamer is appropriate for use in ferrous and non-ferrous materials where tight hole tolerances and fine surface finish are required. The solid carbide construction provides the rigidity needed for high-speed reaming operations, particularly in production environments where tool life and repeatability are priorities. Right-hand cutting direction makes it compatible with standard spindle rotation. Typical applications include fixture bores, bearing seats, and dowel pin holes where accurate final sizing is critical.

Key Features

• Solid carbide construction for rigidity and extended tool life in production use
• 0.343 inch reamer diameter with 6 straight flutes for consistent bore finishing
• Bright polished finish reduces friction and improves chip flow
• Straight shank fits standard chucks and collets without special toolholders
• Right-hand cutting direction for standard spindle rotation
• 1.25 inch flute length suited for moderate-depth hole finishing

Compatibility

Designed as an OEM-style solid carbide chucking reamer for use in standard drill chucks and collet holders on CNC machining centers, knee mills, drill presses, and manual lathes accepting a straight shank tooling of this diameter range.

Installation Notes

Chucking reamers should be installed by a qualified machinist and secured firmly in a chuck or collet before use. Ensure the machine spindle is fully stopped before loading or removing the tool. Apply appropriate cutting fluid for the workpiece material to promote tool life and surface finish quality. Never attempt to ream an undersized hole without proper pre-drilling or boring to the correct prep diameter.
