Hertel 45675832 Chucking Reamer 0.289 in Solid Carbide

Product Description

The HERTEL 45675832 is a solid carbide chucking reamer designed for precision hole finishing in metal and composite workpieces. With a 0.289-inch cutting diameter and six straight flutes ground to a right-hand cutting direction, it delivers tight tolerances and a smooth bore finish in a single pass. The straight shank mounts directly in a drill chuck or collet without adapters. A bright polished finish reduces friction and helps evacuate chips cleanly. At 3.25 inches overall length with a 1.125-inch flute length, it is sized for short-reach applications in CNC machining centers, manual mills, and drill presses. This tool is intended for use by machinists and toolroom professionals working to close hole tolerances.

This chucking reamer is suited for finishing pre-drilled or bored holes in ferrous and non-ferrous metals where final hole size, roundness, and surface finish are critical. It is a common choice in job shops, maintenance machining, and production environments where hole quality must meet fit-and-function requirements for dowel pins, bushings, bearings, or press-fit assemblies. The compact flute length makes it practical for shallow-hole applications and materials where short-flute rigidity improves finish quality.

Key Features

• Solid carbide construction provides rigidity and wear resistance in hard or abrasive materials
• Six straight flutes deliver a consistent finish and even chip load across the cutting edge
• Right-hand cutting direction compatible with standard spindle rotation
• Bright polished finish lowers cutting friction and aids chip clearance
• Straight shank fits standard drill chucks and ER collet systems without adapters
• 0.289-inch diameter falls within the 0.250- to 0.299-inch decimal inch reamer range

Compatibility

Designed as an OEM-style solid carbide chucking reamer for use in CNC machining centers, manual knee mills, and drill presses equipped with a drill chuck or collet capable of accepting a straight shank in the 0.289-inch diameter range.

Installation Notes

This reamer is installed and serviced by machinists and toolroom personnel. Secure the straight shank fully in the chuck or collet before operation and verify runout with a dial indicator when tight tolerances are required. Always ream from a pre-drilled or bored pilot hole sized appropriately undersized for the reaming allowance. Solid carbide tooling is brittle — avoid side loading, interrupted cuts, or dropping the tool on hard surfaces.
