Hertel 72033111 Chucking Reamer 0.3110 in Hss Straight Flute

Product Description

The HERTEL 72033111 is a straight-flute chucking reamer designed for precision hole finishing in metal working applications. Ground from high-speed steel (HSS) with a bright, uncoated finish, this reamer produces accurate, smooth bores to a diameter of 0.3110 inches. The straight-cylindrical shank allows secure seating in standard drill chucks or collet holders. With a 6-inch overall length and a 1.5-inch flute length, it is sized for moderate-depth holes where concentricity and surface finish are critical. Installation and use are handled by machinists and tool-and-die professionals working on precision components.

This chucking reamer is suited for finishing drilled or bored holes in ferrous and non-ferrous metals in machine shop, maintenance, and production environments. The right-hand cutting direction is standard for conventional CNC or manual lathe and milling machine setups. Its 6-flute configuration distributes cutting load evenly, reducing chatter and improving finish quality in through-holes and blind-hole applications where tight tolerances are required.

Key Features

• 0.3110-inch reaming diameter for precise hole finishing
• HSS construction provides toughness and wear resistance in general machining
• 6 straight flutes distribute cutting forces evenly and reduce chatter
• Bright, uncoated finish suitable for use with cutting fluids on a wide range of materials
• Straight-cylindrical shank fits standard drill chucks and collet holders
• Right-hand cutting direction compatible with conventional machine spindle rotation

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks and collet-type tool holders on CNC machining centers, lathes, and manual knee mills accepting straight-cylindrical shank tooling.

Installation Notes

Chucking reamers are installed and operated by qualified machinists. Secure the straight-cylindrical shank firmly in a drill chuck or collet holder, ensuring runout is minimized before operation. Always apply appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Do not use a chucking reamer to remove excessive stock — pre-drill or bore the hole to within 0.005 to 0.015 inches of finish size before reaming.
