Hertel 72556244 Chucking Reamer 0.2480 in Cobalt Steel

Product Description

The HERTEL 72556244 is a straight-flute chucking reamer ground from cobalt steel for precision hole finishing in machine shop and production environments. It carries a 0.2480-inch cutting diameter with a 6-inch overall length and a 1.5-inch flute length. The straight-cylindrical shank seats directly in a drill chuck or collet holder, making setup fast and repeatable. Cobalt steel construction handles harder workpiece materials and elevated cutting temperatures better than standard high-speed steel. The bright, uncoated finish makes wear patterns easy to spot during inspection.

This reamer is suited for dowel pin hole sizing and close-tolerance bore finishing on ferrous and non-ferrous materials. The right-hand cutting direction pairs with standard machine spindle rotation. Typical applications include CNC machining centers, knee mills, and drill presses where a chucking reamer replaces a hand reamer for powered through-feed or peck-reaming operations. The 0.2480-inch diameter falls within the 0.2000 to 0.2499 decimal inch reamer diameter range.

Key Features

• Cobalt steel construction resists heat and wear in harder workpiece materials
• Straight flute geometry suits through-hole and short blind-hole reaming
• Straight-cylindrical shank fits standard drill chucks and collet systems
• Bright uncoated finish for easy wear inspection and regrinding
• Rated as a dowel pin reamer for precision location hole sizing
• Right-hand cutting direction for standard machine spindle rotation

Compatibility

Designed for use in any machine spindle or chucking setup that accepts a straight-cylindrical shank reamer; rated as a dowel pin reamer within the 0.2000 to 0.2499 decimal inch diameter range.

Installation Notes

Chucking reamers are installed and operated by machinists following standard shop practices. Secure the shank fully in a drill chuck or collet and verify runout before cutting. Power down and lock out the machine spindle before changing or inspecting the tool. Reaming allowance, feed rate, and cutting fluid selection should follow the workpiece material guidelines established in your shop's process documentation.
