Checking TIR - Check the reamer diameter with a dial indicator (at the circular margin). Ideally a reamer should run within .001” TIR. Coolant feeding reamers: Coolant induced thru the reamer should be utilitized when possible. Benefits include better finishes, superior tool life and the ability to increase speeds and feeds. Speeds and Feeds:

Carbide tipped reamers are especially appropriate for close tolerance reaming. Because carbide is very highly resistant to wear, the reamer will produce accurate hole size and a smooth finish far longer than high speed steel or cobalt.

Hannibal Carbide Tool is a manufacture of carbide tipped and solid carbide cutting tools including reamers, drills, counterbores, milling cutters, end mills, port contour cutters, centers, countersinks, single points and much more.
Resharpening of carbide tipped drills, reamers, end mills, counterbores, and cutters maximizes tool life. Resharpening information for each type of tool.
Dimension & element tolerances conform to following standard, unless otherwise specified on selected styles: ASME/ANSIB94.11M * ISO * NAS 907 * USCTI “Taper Shank No.” refers to American Standard taper series (formerly Morse taper series) per ASME/ANSI B5.10
These precision ground reamers should be used in pairs, .0005" and .0020" under the dowel pin diameter. The .0020" smaller holes assure a tighter dowel pin fit, so all the pins will remain on the same side upon disassembly.
