For reaming holes without interrupted cuts such as keyways and cross sections
- Straight flute reamers are the most common and used in general purpose though-hole applications
- Designed to convert a straight hole into a tapered hole into which standard taper pins will fit
- The square on the shank is suitable for holding a tap wrench or vise, depending on whether the reamer or part is rotating, making them ideal for hand use
- Steam tempering gives a strongly adhering blue oxide surface that acts to retain cutting fluid and prevent chip to tool welding, thereby counteracting the formation of a built-up edge
- Steam tempering can be applied to any bright tool but is most effective on drills and taps
- +0.0050 tolerance
