Value Collection ATR2645 Taper Pin Reamer Set 17 Pc

Product Description

The VALUE COLLECTION ATR2645 is a 17-piece taper pin reamer set designed for cutting and finishing tapered holes that accept standard taper pins in metal assemblies. Each reamer features a helical flute geometry with a right-hand spiral and right-hand cut, which helps pull chips away from the work surface and reduces chatter during the reaming pass. The set is machined from high speed steel with a bright polished finish. Coverage spans taper pin sizes 7/0 through 10, with large-end diameters ranging from 0.0666 inches up to 0.7216 inches. Machinists, tool and die workers, and maintenance technicians use sets like this for shaft collars, couplings, and precision-located assemblies.

This set applies to general metalworking environments wherever tapered pin connections are specified. Typical applications include machine tool repair, power transmission assemblies, gear hubs, and industrial maintenance work requiring precise taper pin fitment. The straight shank on each reamer is compatible with standard drill chucks and collet holders. All 17 sizes are included in a single set, covering the full range from the smallest 7/0 pin up through the large 10 pin, making it suitable for shops that service a wide variety of machinery.

Key Features

• 17 reamers covering taper pin sizes 7/0 through 10 in a single set
• Large-end diameter range: 0.0666 inches to 0.7216 inches
• Small-end diameter range: 0.0497 inches to 0.5799 inches
• High speed steel construction for durability across a broad range of workpiece materials
• Helical flute, right-hand spiral, right-hand cut geometry for smooth chip evacuation
• Bright polished finish reduces friction and aids chip flow during the cut
• Straight shank fits standard drill chucks and collet holders

Compatibility

Designed for use with standard taper pin holes conforming to ASME taper pin size designations 7/0 through 10. Straight shanks are compatible with common drill chucks and collet-style toolholding systems used on drill presses, lathes, and milling machines.

Installation Notes

Taper pin reamers are typically used by machinists and maintenance technicians working on precision assemblies. Always secure the workpiece firmly before reaming and use cutting fluid appropriate for the workpiece material to extend tool life and improve finish quality. Apply light, consistent feed pressure and clear chips frequently to avoid tool deflection or binding. Inspect the taper hole for proper fit with the mating pin before final assembly.
