Hertel 72033004 Chucking Reamer 0.3000 in Hss 6 Flute

Product Description

The HERTEL 72033004 is a straight-flute chucking reamer designed for precision hole finishing in metal components. Ground from high-speed steel (HSS) with a bright uncoated finish, it cuts right-hand and delivers a consistent bore diameter of 0.3000 inches. The straight-cylindrical shank seats securely in a drill chuck or collet, making it a standard choice for lathe, drill press, and CNC finishing operations. With 6 flutes and a 1.5-inch flute length, the tool removes minimal stock while holding tight diameter tolerances in through-holes and blind holes alike.

This reamer is suited for machine shop, maintenance, and production environments where a 0.3000-inch finished bore is required. It is appropriate for use in ferrous and non-ferrous metals under typical cutting speeds and feeds for HSS tooling. The 6-inch overall length provides reach for standard workholding setups on manual lathes and machining centers. Machinists and tool-and-die professionals select this style for final-pass reaming after drilling and boring operations.

Key Features

• 0.3000-inch reaming diameter with straight-flute geometry for smooth cutting action
• 6 flutes for improved surface finish and stock removal balance
• High-speed steel (HSS) construction handles a broad range of workpiece materials
• Bright uncoated finish — ready to use as supplied or receptive to aftermarket coatings
• Straight-cylindrical shank fits standard drill chucks and collet holders
• Right-hand cutting direction, compatible with conventional CW spindle rotation

Compatibility

Designed as a standard chucking reamer for machine tool spindles accepting a straight-cylindrical shank. Fits drill chucks, ER collets, and similar workholding devices sized for a 0.3000-inch diameter shank tool.

Installation Notes

Installation and use should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before mounting or removing the reamer. Secure the straight-cylindrical shank firmly in a concentric chuck or collet to minimize runout. Always apply appropriate cutting fluid for the workpiece material and follow manufacturer feed-and-speed recommendations for HSS reamers.
