Hertel 72022155 Chucking Reamer 0.2215 in Hss 6 Flute

Product Description

The HERTEL 72022155 is a high-speed steel (HSS) chucking reamer designed to finish-ream drilled or bored holes to a precise 0.2215-inch diameter. With a straight-cylindrical shank and 6 straight flutes, this reamer delivers accurate hole sizing and smooth surface finish in a wide range of ferrous and non-ferrous materials. The right-hand cutting direction and bright/uncoated finish make it well suited for general-purpose machine reaming in CNC machining centers, drill presses, and manual lathes. At 6 inches overall length with a 1.5-inch flute length, it fits standard chucks and collets without extended-reach adapters.

This chucking reamer is used in machine shops, maintenance facilities, and manufacturing environments where hole tolerance and surface finish are critical. It is appropriate for both production and repair work on steel, cast iron, aluminum, brass, and similar materials. The straight-flute geometry is preferred for through-holes and materials that produce broken chips. Licensed machinists and tool-and-die technicians are the primary users, though it is also suitable for skilled maintenance mechanics working to print tolerances.

Key Features

• 0.2215-inch reamer diameter for precision hole finishing
• High-speed steel (HSS) construction for durability across a broad range of work materials
• 6 straight flutes for smooth cutting action and chip clearance in through-hole applications
• Right-hand cutting direction for use with standard machine spindle rotation
• Straight-cylindrical shank for secure seating in drill chucks and collet holders
• Bright/uncoated finish — no coating buildup to affect dimensional accuracy

Compatibility

Designed as a general-purpose machine chucking reamer compatible with standard drill chucks and collets accepting a straight-cylindrical shank in the 0.2000 to 0.2499-inch diameter range.

Installation Notes

Always secure the reamer in a rigid chuck or collet and verify runout before reaming to tolerance. Pre-drill or bore the hole to the recommended undersize before using a chucking reamer, as reamers are finishing tools and are not designed to remove large amounts of material. Use appropriate cutting fluid for the work material to extend tool life and improve surface finish. Follow shop safety protocols and machine guarding requirements when operating rotating cutting tools.
