Hertel 72021603 Chucking Reamer 0.2160 in Hss 6 Flute

Product Description

The HERTEL 72021603 is a straight-flute chucking reamer designed to finish-ream precision holes to a diameter of 0.2160 inches. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent dimensional accuracy in ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in standard drill chucks or collet holders. With six flutes and a right-hand cutting direction, the tool produces smooth bore surfaces in a single pass. Machinists and tool-and-die professionals use this reamer for close-tolerance finishing operations on manual mills, lathes, and CNC drilling centers.

This reamer is suited for light industrial and precision machining environments where hole diameter control is critical. Its 1.25-inch flute length handles typical through-hole and shallow blind-hole applications in the 0.2000 to 0.2499 inch diameter range. The 5-inch overall length provides enough reach for most standard fixturing setups without excessive overhang. It is sold individually and is appropriate for job shops, maintenance departments, and production machining operations requiring repeatable finish-reaming results.

Key Features

• 0.2160 inch finished bore diameter with 6 straight flutes for smooth surface finish
• High-speed steel (HSS) construction for durability across ferrous and non-ferrous workpieces
• Bright, uncoated finish suitable for use with standard cutting fluids
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Right-hand cutting direction with 1.25-inch flute length for shallow and through-hole reaming
• 5-inch overall length for versatile fixturing in manual and CNC applications

Compatibility

Designed as an OEM-style chucking reamer for use in the 0.2000 to 0.2499 inch reamer diameter range, compatible with standard drill chucks and collet holders accepting a straight-cylindrical shank.

Installation Notes

This reamer is installed and operated by machinists following standard shop practices. Before mounting, ensure the spindle, chuck, or collet holder is fully de-energized and at rest. Secure the straight-cylindrical shank firmly in the chuck or collet to minimize runout. Always apply an appropriate cutting fluid for the workpiece material and never force the reamer into an undersized pilot hole, as this risks tool breakage and out-of-tolerance bores.
