Hertel 72401003 Taper Pin Reamer Size 0 Hss 6 Flute

Product Description

The HERTEL 72401003 is a straight-flute taper pin reamer designed for enlarging, finishing, and shaping tapered holes to accept standard taper pins. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers general-purpose performance across a range of ferrous and non-ferrous workpiece materials. The reamer is sized for a No. 0 taper pin, with a small end diameter of 0.1287 inches and a large end diameter of 0.1638 inches. With 6 flutes and a right-hand cut, it produces clean, accurate tapered bores in one pass when properly set up in a drill press or manual operation.

This reamer is suited for machine shops, maintenance facilities, and job sites where taper pin connections are used in shafts, hubs, and mechanical assemblies. The square shank provides positive drive engagement in standard tap wrenches and T-handle drivers, making it practical for both bench and field use. The 1.6875-inch flute length and 2.9375-inch overall length keep the tool compact for work in confined assemblies. It is typically used by machinists, toolmakers, and maintenance technicians performing precision hole finishing on light- to medium-duty mechanical components.

Key Features

• No. 0 taper pin size with a 1:48 taper rate for standardized fitment
• High-speed steel construction for durability across general-purpose cutting applications
• 6 straight flutes with right-hand cut for consistent, controlled material removal
• Square shank (0.1719 inches) for positive drive in tap wrenches and T-handle drivers
• Bright, uncoated finish suitable for use with cutting fluids on a wide range of materials
• Compact overall length of 2.9375 inches for use in tight assemblies

Compatibility

Designed as an OEM-style replacement or standard tooling option for No. 0 taper pin reaming applications in mechanical assemblies requiring a 1:48 taper ratio per standard taper pin specifications.

Installation Notes

Taper pin reamers are typically operated by machinists or maintenance technicians using a tap wrench, T-handle, or drill press at low speed with appropriate cutting fluid applied to the flutes. Secure the workpiece firmly before reaming to prevent movement and ensure hole concentricity. Advance the reamer gradually with consistent pressure, clearing chips frequently to avoid flute loading. Always wear appropriate eye protection and follow shop safety practices when operating cutting tools.
