Hertel 72401102 Taper Pin Reamer Size 10 Hss 8 Flutes

Product Description

The HERTEL 72401102 is a straight-flute taper pin reamer designed for enlarging, finishing, and shaping tapered holes to accept standard taper pins. Built from high-speed steel with a bright, uncoated finish, this reamer delivers consistent material removal across a 1:48 taper rate. It features 8 straight flutes and a right-hand cutting direction, producing a clean finish in both ferrous and non-ferrous workpiece materials. The square shank provides positive drive in a standard reamer driver or drill press chuck. With a small end diameter of 0.5799 inches and a large end diameter of 0.7216 inches, it is sized for No. 10 taper pin applications. Machinists, tool and die tradespeople, and maintenance mechanics typically reach for this tool during precision assembly and repair work.

This reamer is used wherever a No. 10 taper pin seat must be cut or restored to correct size. Typical applications include machine tool repair, power transmission component assembly, agricultural equipment maintenance, and general industrial manufacturing. It is appropriate for use in manual drill presses, milling machines, and hand-held reaming operations where a square-drive reamer wrench is employed. General-purpose tool performance rating makes it suitable for a wide range of shop environments and production volumes.

Key Features

• No. 10 taper pin size with a 1:48 taper rate for standard taper pin seating
• High-speed steel construction for durability across ferrous and non-ferrous materials
• 8 straight flutes for consistent chip evacuation and smooth bore finish

Compatibility

Designed as an OEM-style replacement and standard tooling option for No. 10 taper pin reaming operations in general industrial and maintenance machining applications.

Installation Notes

This reamer is installed and operated by qualified machinists or maintenance mechanics familiar with precision hole finishing procedures. Secure the workpiece fully before beginning the reaming operation, and ensure the spindle or reamer wrench is properly aligned with the existing pilot hole to avoid deflection. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Always follow shop safety protocols and applicable OSHA machine guarding requirements when operating rotating cutting tools.
