Helical Flute Taper Pin Reamers
- Tapered reamers turn a straight hole into a tapered hole into which standard taper pins will fit
- The straight-flute and spiral-flute reamers are generally used by hand while the helical-flute is designed for machine use
- The square on the shanks of the straight and spiral fluted are suitable for holding in a tap wrench or vise
- The straight flute taper pin reamer is recommended for most materials
- The spiral flute taper pin reamer is recommended for applications where the reamer tends to wedge itself
- The Helical-flute Taper pin reamer has the geometry for reaming holes for tapered pins with a machine
- The free cutting action at high speeds produces a good finish and minimizes chip packing in the flutes.
