Hertel 72403108 Taper Pin Reamer No 10 Hss

Product Description

The HERTEL 72403108 is a No. 10 taper pin reamer designed for enlarging, finishing, and shaping tapered holes to accept standard taper pins. Made from high-speed steel (HSS) with a bright, uncoated finish, this reamer features three helical flutes with a right-hand cut and left-hand spiral. The small end diameter measures 0.5799 inches and the large end measures 0.7216 inches, following a 1:48 taper rate. The 5/8-inch straight shank and 9.3125-inch overall length make it compatible with standard drill press and milling machine setups. Machinists, tool-and-die technicians, and maintenance professionals use this tool for general-purpose reaming operations requiring precise taper pin fitment.

The HERTEL 72403108 is suited for general-purpose reaming in maintenance, repair, and production machining environments. It is used wherever No. 10 taper pins must be seated accurately into drilled holes, such as in shaft-to-hub connections, pivot assemblies, and mechanical linkage components. This reamer is appropriate for both manual machine operation and CNC setups with appropriate speeds and feeds for HSS tooling.

Key Features

• No. 10 taper pin size with a 1:48 taper rate for standard taper pin fitment
• High-speed steel construction for general-purpose machining performance
• Three helical flutes with right-hand cut and left-hand spiral for smooth chip evacuation
• Bright, uncoated finish suitable for use with cutting fluids
• 5/8-inch straight shank compatible with standard collets and chucks
• 6.8125-inch flute length provides extended contact for deep or through-hole applications

Compatibility

Designed as an OEM-style general-purpose reamer for No. 10 taper pin applications in standard drill press, milling machine, and CNC setups accepting a 5/8-inch straight shank.

Installation Notes

This reamer is installed and operated by machinists and tool-and-die technicians. Before use, ensure the workpiece is securely fixtured and the machine spindle is powered down when mounting the tool. Apply an appropriate cutting fluid for high-speed steel tooling to extend tool life and improve finish quality. Do not exceed recommended speeds for HSS reamers, as excessive RPM can cause premature wear or tool failure.
