Hertel 2330173 Hand Reamer 1-1/2 in 12 Flute Hss

Product Description

The HERTEL 2330173 is a hand reamer designed for precision hole finishing in metalworking and machining applications. It measures 1.5 inches in diameter with a 6.5-inch spiral flute length and an overall length of 13 inches. Constructed from high speed steel with a bright, uncoated finish, this reamer delivers accurate final sizing and smooth bore surfaces in drilled or bored holes. It features 12 flutes with a left-hand spiral direction and a right-hand cutting direction, a combination that helps reduce chatter and pull chips away from the cutting edge during hand-reaming operations. The straight shank fits standard reamer drivers and tap wrenches.

This reamer is suited for finishing holes to close tolerances in a range of ferrous and non-ferrous workpieces. It is commonly used in job shop, maintenance, and production environments where precise hole sizing is required before fitting pins, bushings, or other close-tolerance components. The 1.5-inch diameter makes it appropriate for larger bore finishing tasks encountered in heavy equipment repair, toolroom work, and general machine shop applications. A licensed machinist or skilled maintenance technician typically performs this operation.

Key Features

• 1.5-inch reamer diameter for larger bore finishing applications
• 12 spiral flutes with left-hand spiral direction for reduced chatter and improved chip evacuation
• Right-hand cutting direction for standard hand-reaming operation
• High speed steel construction for durability across a broad range of workpiece materials
• Bright, uncoated finish suitable for use with cutting fluids
• Straight shank compatible with standard tap wrenches and reamer drivers

Compatibility

Designed as a general-purpose hand reamer for finishing holes to 1.5-inch diameter in metalworking and machining applications where a straight-shank tool is required.

Installation Notes

Hand reamers are installed and operated by machinists or maintenance technicians using a tap wrench or suitable driver. The workpiece and any machine spindle must be fully de-energized and secured before reaming. Apply an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Never reverse the cutting direction during a hand-reaming pass, as this can damage the cutting edges.
