Hertel 45675709 Chucking Reamer 0.27 in Solid Carbide

Product Description

The HERTEL 45675709 is a solid carbide chucking reamer designed for precision hole finishing in metalworking applications. With a 0.27-inch reaming diameter, 6 straight flutes, and a right-hand cutting direction, this tool delivers consistent, accurate bore sizing when run in a CNC machining center, drill press, or manual lathe. The straight shank mounts directly in a standard chuck or collet without adapters. A bright polished finish reduces friction and helps evacuate chips cleanly. Overall length is 3.25 inches with a 1.125-inch flute length, making it well-suited for moderate-depth through-holes and blind holes in steel, aluminum, and similar workpiece materials.

This chucking reamer is intended for production and maintenance machining environments where final hole diameter and finish must meet tight tolerances. Machinists and tool-and-die professionals reach for solid carbide reamers when working harder materials or running higher spindle speeds than high-speed steel tooling can handle. The straight flute geometry keeps the tool stable in short-to-medium depth holes and makes it straightforward to regrind when the cutting edges dull.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• 6 straight flutes for controlled cutting action and clean chip evacuation
• Right-hand cutting direction compatible with standard spindle rotation
• Bright polished finish reduces built-up edge and lowers cutting friction
• Straight shank seats directly in a drill chuck or precision collet holder
• 0.27-inch diameter falls within the 0.25 to 0.2999-inch decimal reamer range

Compatibility

Designed as an OEM-style replacement or standard tooling option for machine shops requiring a 0.27-inch chucking reamer in the 0.25 to 0.2999-inch decimal diameter range with a straight shank and straight flute geometry.

Installation Notes

Chucking reamers are installed by qualified machinists in a chuck, collet, or floating reamer holder on a machine tool. The workpiece bore should be pre-drilled or bored to within a few thousandths of final size before reaming. Always bring the spindle to a full stop and follow lockout procedures before changing tooling. Cutting fluid is recommended to extend tool life and improve hole finish.
