Hertel 72011554 Chucking Reamer 0.1155 in Hss 4 Flute

Product Description

The HERTEL 72011554 is a straight-flute chucking reamer designed to finish-ream precision holes to a diameter of 0.1155 inches. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers clean, accurate bore finishes in a wide range of ferrous and non-ferrous workpiece materials. The straight-cylindrical shank seats securely in standard chucks and collets on drill presses, lathes, and CNC machining centers. With four flutes and right-hand cutting direction, it removes material evenly and exits cleanly. Overall length is 3.5 inches with a flute length of 0.875 inches. At 0.15 pounds, it is a lightweight, single-piece tool suited for production and maintenance machining environments.

This reamer is appropriate for applications requiring tight hole tolerances in the 0.1000 to 0.1499 inch diameter range. Typical use cases include precision hole finishing in small mechanical assemblies, tooling fixtures, and component repair work. The straight-cylindrical shank makes it compatible with standard drill chucks and ER collet systems without the need for specialty toolholders. It is sold individually and is well suited for machine shops, maintenance facilities, and industrial toolrooms performing light-to-medium reaming operations on metal workpieces.

Key Features

• 0.1155 inch finished bore diameter for precision hole sizing
• High-speed steel (HSS) construction for durability across a broad range of materials
• Bright, uncoated finish — no coating buildup to affect tolerances
• 4 straight flutes with right-hand cutting direction for smooth, consistent stock removal
• Straight-cylindrical shank fits standard chucks and collets without adapters
• Compact 3.5 inch overall length suits close-clearance machining setups

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and CNC machining centers equipped with standard drill chucks or collet systems accepting a straight-cylindrical shank in the 0.1000 to 0.1499 inch diameter class.

Installation Notes

A licensed machinist or qualified toolroom operator should install and operate this reamer. Secure the straight-cylindrical shank firmly in a chuck or collet before use and verify runout with a dial indicator to ensure concentricity. Always power down and lock out the machine spindle before changing tooling. Apply appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality.
