Hertel 45676525 Chucking Reamer 0.3755 in Solid Carbide

Product Description

The HERTEL 45676525 is a solid carbide chucking reamer designed for precision hole finishing in metalworking applications. With a diameter of 0.3755 inches and a 6-flute straight flute geometry, it delivers tight tolerances and a smooth bore finish in a single pass. The straight shank mounts directly into standard drill chucks or collet holders. At 3.5 inches overall length with a 1.25-inch flute length, it suits both manual and CNC drilling setups. The bright polished finish reduces friction and aids chip evacuation. Right-hand cutting direction is standard for conventional feed. Machinists and toolroom technicians are the primary users of this tool.

This reamer is suited for finishing drilled or bored holes in ferrous and non-ferrous metals where close dimensional tolerances are required. It is commonly used in job shops, production machining, and toolroom environments. Typical applications include reaming holes for dowel pins, bushings, and precision-fit fasteners. The 0.3755-inch diameter falls within the 0.3500 to 0.3999 inch range, making it appropriate for finishing holes in that size class without oversize or undersize offset geometry.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 0.3755-inch diameter for precise hole sizing within the 0.3500 to 0.3999 inch range
• 6-flute straight flute design provides smooth finish and stable cutting action
• Bright polished coating reduces friction and aids chip flow
• Right-hand cutting direction compatible with standard spindle rotation
• Straight shank fits standard drill chucks and collet holders without adapters

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, milling machines, and CNC machining centers equipped with a straight-shank collet or drill chuck capable of accepting the shank diameter.

Installation Notes

Installation and use of this tool should be performed by qualified machinists or toolroom technicians. Secure the straight shank firmly in the chuck or collet before operation and verify runout before cutting. Power down the machine and lock out energy sources before changing or inspecting tooling. Do not use this reamer to remove excessive stock — pre-drill or bore the hole close to final size before reaming.
