Hertel 72009053 Chucking Reamer 0.0905 in Hss Straight

Product Description

The HERTEL 72009053 is a straight-flute chucking reamer designed for precise hole finishing in machine shop and production environments. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing and smooth surface finishes in a wide range of ferrous and non-ferrous materials. The reamer measures 0.0905 inches in diameter with a 3-inch overall length and a 3/4-inch flute length. Its straight-cylindrical shank seats securely in standard drill chucks or collet holders. With four right-hand cutting flutes, it provides consistent chip evacuation and dimensional accuracy. Machinists, tool-and-die makers, and production operators use this reamer for finishing drilled or bored holes to close tolerances.

This reamer is suited for light to medium reaming operations on CNC machining centers, manual lathes, and drill presses where a small-diameter finished bore is required. The 0.0905-inch diameter places it in the small-bore range, making it applicable to precision instrument components, hydraulic fittings, and similar close-tolerance work. The straight flute geometry is effective in shorter-chipping materials and provides easy visual inspection of cutting edge condition during use.

Key Features

• 0.0905-inch reamer diameter for small-bore precision finishing
• High-speed steel (HSS) construction for durability across general-purpose machining applications
• Four straight flutes with right-hand cutting direction for consistent chip flow
• Bright, uncoated finish suitable for use with standard cutting fluids
• Straight-cylindrical shank for compatibility with drill chucks and collet holders
• 3-inch overall length with 3/4-inch flute length for controlled reach in shallow bores

Compatibility

Designed as a general-purpose chucking reamer for use in standard drill chucks and collet-style toolholders on CNC and manual machine tools requiring a 0.0905-inch finished bore diameter.

Installation Notes

Chucking reamers are installed and operated by machinists and tool-and-die professionals. Ensure the spindle is fully stopped and the machine is powered down before changing or inspecting tooling. Secure the straight-cylindrical shank fully within the chuck or collet to prevent runout, and always apply appropriate cutting fluid for the workpiece material. Do not use a chucking reamer to remove excessive stock; pre-drill or bore the hole to within the recommended allowance before reaming.
