Hertel 4599759 Chucking Reamer 2.00mm Cobalt Steel

Product Description

The HERTEL 4599759 is a cobalt steel chucking reamer designed to finish-ream precision holes to a 2.00mm (0.0787 inch) diameter. Built with 4 straight flutes and a bright, uncoated finish, it delivers accurate sizing and smooth surface finish in ferrous and heat-resistant alloys where high-speed steel tooling falls short. The straight-cylindrical shank seats securely in a drill chuck or collet, making it a reliable choice for manual machines, CNC lathes, and drill presses. Machinists and toolroom technicians use this reamer when tight hole tolerances are required after drilling.

This reamer is suited for light-material and precision hole-finishing applications in machine shops, toolrooms, and production environments. At 3 inches overall length with a 3/4 inch flute length, it is sized for shallow through-holes and blind holes in small workpieces. The right-hand cutting direction is compatible with standard spindle rotation. Cobalt steel construction provides elevated heat and wear resistance compared to standard M2 HSS, extending tool life in tougher materials.

Key Features

• 2.00mm (0.0787 inch) reamer diameter for precise hole finishing
• Cobalt steel construction resists heat and wear in hard or abrasive materials
• 4 straight flutes provide consistent chip evacuation and smooth bore finish
• Right-hand cutting direction matches standard machine spindle rotation
• Straight-cylindrical shank fits standard drill chucks and collet holders
• Bright, uncoated finish — no coating buildup to affect final hole size

Compatibility

Designed as a standard chucking reamer for use in drill presses, CNC lathes, milling machines, and manual turret lathes equipped with a chuck or collet capable of holding a straight-cylindrical shank at 2.00mm diameter.

Installation Notes

A licensed machinist or toolroom technician should secure the shank firmly in a properly sized collet or drill chuck before use. Always power down and lock out the machine spindle before inserting or removing the tool. Apply appropriate cutting fluid for the workpiece material to reduce heat buildup and extend tool life. Pre-drill the hole to the correct pilot diameter before reaming — do not use a chucking reamer to originate a hole.
