Taper pins are self-locking, interference-fit fasteners used to locate and lock components on shafts — common applications include gear hubs, coupling flanges, crank handles, and shaft collars where the pin must resist rotational and axial loads.\u003c\/p\u003e\n\n\u003ch2\u003eSutton Tools and Bordo\u003c\/h2\u003e\n\u003cp\u003eAIMS stocks taper pin reamers in high speed steel (HSS) from Sutton Tools and Bordo. Sutton's R105 series covers the standard taper pin reamer range in HSS for hand and machine reaming. Bordo supplies both metric and imperial HSS taper pin reamers, covering the taper pin sizes most commonly used in Australian engineering workshops and maintenance applications.\u003c\/p\u003e\n\n\u003ch2\u003eTaper Pin Standards — Metric and Imperial\u003c\/h2\u003e\n\u003cp\u003eTaper pins are made to both metric (ISO 8734) and imperial (ASME B18.8.2) standards. The standard taper is 1:50 (approximately 1.15°) on the diameter — the same self-locking taper used across both metric and imperial pin standards. When selecting a taper pin reamer, match it to the pin number (metric) or size number (imperial) of the pin being fitted, not just the nominal diameter, to ensure the correct taper length and entry diameter.\u003c\/p\u003e\n\n\u003ch2\u003eReaming Technique\u003c\/h2\u003e\n\u003cp\u003eTaper pin holes are typically drilled undersize, then reamed to the finished taper using the reamer. Good results require a correctly-sized pilot hole, a slow cutting speed, cutting oil, and steady axial feed without side pressure. The pin should enter the reamed hole with hand pressure and lock firmly when driven home — if the pin bottoms out before locking, the hole is over-reamed and the assembly should be reworked.
