Hertel 72013956 Chucking Reamer 0.1395 in Hss 4 Flute

Product Description

The HERTEL 72013956 is a high-speed steel (HSS) chucking reamer designed for precision hole finishing in metalworking applications. With a reamer diameter of 0.1395 inches and an overall length of 4 inches, this tool delivers accurate, repeatable results in drill press, lathe, and CNC machine setups. The bright, uncoated finish is standard for general-purpose HSS reamers used on ferrous and non-ferrous materials. Four straight flutes and a right-hand cutting direction provide smooth material removal and consistent hole sizing. Licensed machinists and tool-and-die technicians are the primary users of this type of precision reamer.

This chucking reamer is suited for production and job-shop environments where tight hole tolerances are required. The straight-cylindrical shank allows direct mounting in drill chucks, collets, and floating reamer holders. With a 1-inch flute length, it is well matched to shallow-to-moderate depth holes in a variety of workpiece materials. It is sold individually and is appropriate for both manual and CNC-driven reaming operations.

Key Features

• 0.1395 inch reamer diameter for precise hole finishing
• 4-inch overall length with 1-inch flute length for controlled cutting depth
• High-speed steel (HSS) construction for durability across general-purpose materials
• Straight-cylindrical shank for secure chuck or collet mounting
• Four straight flutes with right-hand cutting direction
• Bright, uncoated finish — no additional coating to affect dimensional accuracy

Compatibility

Designed as a general-purpose chucking reamer compatible with drill presses, engine lathes, and CNC machining centers equipped with standard drill chucks or collet holders accepting a straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists familiar with reaming operations and machine tool safety. Ensure the machine spindle is fully stopped and locked out before mounting or removing the reamer. Use a properly sized chuck or collet to minimize runout and protect the reamer shank. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish.
