Hertel 72014855 Chucking Reamer 0.1485in Hss Straight Flute

Product Description

The HERTEL 72014855 is a straight-flute chucking reamer designed to bring drilled or bored holes to a precise final diameter. Ground from high-speed steel (HSS) with a bright, uncoated finish, it holds a cutting diameter of 0.1485 inches across four right-hand flutes. The straight-cylindrical shank seats securely in a drill chuck, collet, or machine spindle. At 4 inches overall length with a 1-inch flute length, this reamer is sized for short, rigid setups in drill presses, lathes, and CNC machining centers. Machinists and toolroom technicians reach for this tool when hole tolerances and surface finish requirements exceed what a twist drill alone can deliver.

This chucking reamer is suited to light production and toolroom work in both job-shop and maintenance environments. It performs in ferrous and non-ferrous materials where a close-tolerance hole finish is required. The 0.1485-inch diameter falls within the 0.1000 to 0.1499-inch decimal-inch reamer range, making it appropriate for applications such as dowel pin holes, precision bearing bores, and jig-plate work where fit and finish are critical. It is intended for machine use, not hand reaming.

Key Features

• Ground HSS construction provides a balance of hardness and toughness for general-purpose reaming
• Bright, uncoated finish suitable for use with standard cutting fluids across a range of materials
• Four straight flutes deliver consistent chip clearance and a smooth bore finish
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight-cylindrical shank fits drill chucks, ER collets, and straight-bore toolholders without adapters
• Compact 4-inch OAL and 1-inch flute length support short, rigid setups that minimize chatter

Compatibility

Designed as a standard straight-cylindrical-shank chucking reamer for use in drill presses, lathes, turret machines, and CNC machining centers equipped with a compatible chuck or collet system.

Installation Notes

Machine reaming is typically performed by machinists or toolroom technicians following standard metal-cutting practices. Power down and lock out the machine spindle before loading or changing the reamer. Secure the shank fully in the chuck or collet before starting the spindle, and verify runout with a dial indicator when close tolerances are required. Always apply an appropriate cutting fluid for the workpiece material, and never reverse spindle direction while the reamer is engaged in the bore.
