To ensure that the bridge and end pins fit well and hold reliably, this reamer shapes the mounting holes to an accurate 3° taper.
The steel blade has four flutes to provide a smooth, chatter-free cut even in dense woods. Cut length is 3 3/4" with a maximum diameter of 5/16".
Including the pinned hardwood handle, it is 5 1/4" long overall.
