Hertel 72010853 Chucking Reamer 0.1085 in Hss 4 Flute

Product Description

The HERTEL 72010853 is a straight-flute chucking reamer designed for precision hole finishing in metal workpieces. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent bore sizing in drilling and machining operations. The reamer measures 0.1085 inches in diameter with a 3.5-inch overall length and a 7/8-inch flute length. Its straight-cylindrical shank seats securely in standard drill chucks, collets, and machine tool holders. The right-hand cutting direction and 4-flute configuration make it well-suited for achieving close-tolerance finishes in production and toolroom environments.

This chucking reamer is used in machine shop, toolroom, and production floor applications where accurate final hole sizing is required. It is appropriate for use in drill presses, lathes, CNC machining centers, and manual milling machines. The 0.1085-inch diameter falls within the 0.1000 to 0.1499 inch decimal inch reamer range, making it a standard choice for finishing small-diameter bores in ferrous and non-ferrous materials. Machinists and tool and die technicians typically deploy this type of reamer as a finishing step following a drilled or bored undersize hole.

Key Features

• 0.1085-inch cutting diameter for precise hole finishing in the 0.1000 to 0.1499 inch range
• HSS construction provides wear resistance and edge retention in standard machining applications
• 4 straight flutes with right-hand cutting direction for smooth, consistent material removal
• Straight-cylindrical shank for easy chuck or collet mounting without special adapters
• Bright, uncoated finish suitable for general-purpose reaming operations
• 3.5-inch overall length provides adequate reach for typical workpiece depths

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, milling machines, and CNC machining centers accepting a straight-cylindrical shank tool holder or collet of appropriate bore size.

Installation Notes

Installation is performed by qualified machinists or tool and die technicians. Secure the straight-cylindrical shank firmly in a drill chuck or collet before operation and verify runout before engaging the workpiece. Always ream from a properly sized drilled or bored undersize hole — never attempt to remove excess material in a single pass beyond the reamer's intended stock allowance. Ensure the workpiece is clamped securely and appropriate cutting fluid is applied to extend tool life and maintain bore finish quality.
