Hertel 72013550 Chucking Reamer 0.1355in Hss 4 Flute

Product Description

The HERTEL 72013550 is a high-speed steel (HSS) chucking reamer designed for precision hole finishing in metal and similar materials. With a 0.1355-inch cutting diameter and four straight flutes, it removes minimal material while delivering accurate, smooth bore surfaces. The straight-cylindrical shank seats securely in standard drill chucks and collet holders. At 3.5 inches overall length with a 0.875-inch flute length, this is a compact reamer suited for short-reach applications in production and job-shop environments. The bright, uncoated finish is standard for general-purpose HSS tooling used across a range of ferrous and non-ferrous workpieces.

This reamer is intended for machine-driven finish reaming in CNC machining centers, lathes, drill presses, and similar equipment. It is applied in production scenarios where hole diameter consistency and surface finish quality are critical — common in automotive, aerospace, and general metalworking shops. Right-hand cutting direction is standard for conventional spindle rotation. The compact overall length makes it well-suited for fixture-held or short-reach drilling operations where tool clearance is limited.

Key Features

• 0.1355-inch cutting diameter for precise hole finishing in the 0.1000 to 0.1499-inch range
• Four straight flutes provide clean, consistent material removal
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight-cylindrical shank for use with standard drill chucks and collet holders
• HSS construction with bright, uncoated finish for general-purpose metalworking applications
• Compact 3.5-inch OAL suitable for short-reach and fixured operations

Compatibility

Designed as a general-purpose machine chucking reamer for use in standard drill chucks and collet-style toolholders on CNC machining centers, drill presses, and lathes.

Installation Notes

Chucking reamers are installed and operated by machinists in machine tool environments. Ensure the machine spindle is fully stopped and powered down before mounting or removing the tool from the chuck or collet. Verify shank seating and runout before beginning a reaming pass. Reamers are finishing tools and should not be used to remove large amounts of material — pre-drill or bore to the appropriate undersize before reaming.
