Rule of thumb is 1% for hand reaming and 2% for machine reaming you can go more than this on larger reamers.Click to see full answer. Regarding this, how should a reamer be removed from a finished hole?Remove the reamer from the hole by turning clockwise and raising the reamer at the same time. Note: Do not turn counterclockwise at any time – doing so dulls the reamer. Reaming feeds are usually higher than those used for drilling.Furthermore, how do you make a reamer cut bigger? Just make sure you put “Highway To The Dangerzone” on the shop radio first. You can also use a drill blank and diamond compound. Don’t know about a reamer, but to get a drill to cut bigger I’ve had to sharpen just 1 flute. Running with oil will cause the cut to be slightly larger, generally a couple tenths. Also Know, how is Reamer size calculated? Measure up from the middle of the shaft, perpendicular to your straightedge. Double this measurement to calculate your reamer’s true diameter. Don’t try to cut corners and take measurements by simply following the angle of the blade or measuring the body of the reamer.How fast do you run a reamer?Run at a spindle speed of about 1,800 rpm, the previous reamers took 3 to 4 seconds to finish a hole, whereas cut time for the new tool is 0.14 seconds per bore while running at 4,385 rpm, a 453-sfm cutting speed and a 157-ipm feed rate.
