Hertel 72016553 Chucking Reamer 0.1655 in Hss 6 Flute

Product Description

The HERTEL 72016553 is a high-speed steel (HSS) chucking reamer designed to finish-ream drilled or bored holes to close tolerances. The 0.1655-inch diameter cutting head features six straight flutes with a right-hand cutting direction, producing clean, accurate hole walls in a single pass. At 4.5 inches overall length with a 1.125-inch flute length, this reamer fits standard drill press and CNC lathe chucks via its straight-cylindrical shank. The bright, uncoated finish suits use in general-purpose materials including mild steel, aluminum, brass, and plastics. Machinists and tool-and-die professionals reach for this size when final hole diameter must be held to tight tolerances that drilling alone cannot achieve.

This chucking reamer is suited to bench drill press, turret lathe, and CNC turning center applications where a straight-cylindrical shank can be gripped directly in a drill chuck or collet. It falls within the 0.1500-to-0.1999-inch diameter range, making it a standard selection for finish-reaming small-diameter holes in production and maintenance machining environments. Sold individually, it is a practical stocking item for job shops, maintenance departments, and toolrooms requiring consistent hole quality at this diameter.

Key Features

• 0.1655-inch diameter delivers precise finished-hole sizing in the 0.1500-to-0.1999-inch range
• Six straight flutes provide smooth cutting action and efficient chip clearance
• Right-hand cutting direction for standard machine rotation
• HSS construction offers good toughness and wear resistance across common workpiece materials
• Straight-cylindrical shank mounts directly in drill chucks and collets without adapters
• Bright, uncoated finish suitable for general-purpose machining applications

Compatibility

Designed as a standard chucking reamer for use in drill presses, turret lathes, and CNC turning centers capable of accepting a straight-cylindrical shank tool at this diameter range.

Installation Notes

This reamer should be installed by a qualified machinist following standard toolholding procedures for straight-shank cutting tools. Ensure the machine spindle is fully stopped and power is isolated before mounting or removing the tool from the chuck or collet. Use appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Do not use a chucking reamer to remove excessive stock; pre-drill or bore the hole close to final size before reaming.
