Hertel 72030554 Chucking Reamer 0.3055 in Hss 6 Flute

Product Description

The HERTEL 72030554 is a straight-flute chucking reamer designed for precision hole finishing in metal workpieces. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing at 0.3055 inches in diameter with a 6-inch overall length and a 1-1/2-inch flute length. The straight-cylindrical shank seats securely in a drill chuck or collet holder for controlled, repeatable cuts. With six flutes and right-hand cutting geometry, it removes material smoothly while maintaining tight dimensional tolerances. Machinists and tool-and-die professionals use this reamer to bring drilled or bored holes to final size with minimal runout.

This chucking reamer is suited for production and maintenance machining environments where close-tolerance hole sizing is required. It is appropriate for use in drill presses, lathes, and CNC machining centers equipped with a compatible chuck or collet. The straight flute geometry makes it a practical choice for through-holes in softer metals and general-purpose ferrous and non-ferrous stock. The 0.3055-inch diameter falls within the 0.3000 to 0.3499 decimal inch reamer range, making it a standard selection for hole finishing in that size bracket.

Key Features

• 0.3055-inch reaming diameter for precise hole finishing
• HSS construction provides durability across a range of workpiece materials
• Bright, uncoated finish suitable for general-purpose machining applications
• Six straight flutes with right-hand cutting direction for smooth material removal
• Straight-cylindrical shank for direct chucking in standard drill chucks or collets
• 6-inch overall length with 1-1/2-inch flute length for controlled reach and engagement

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and machining centers equipped with a drill chuck or collet that accepts a straight-cylindrical shank in the corresponding diameter range.

Installation Notes

Installation and use should be performed by a qualified machinist. Ensure the spindle is fully stopped and the machine is powered down before loading or removing the reamer from the chuck. Secure the straight-cylindrical shank firmly in the chuck or collet to minimize runout before operation. Always use appropriate cutting fluid for the workpiece material to extend tool life and maintain hole quality.
