Cutting Speeds & RPM Calculations

The drill press RPM setting for reaming depends on the cutting speed of the material and the size of the ream. The RPM setting will change with the size of the ream. As the ream gets smaller, the RPM must increase to maintain the recommended surface footage. Although you will find specific cutting speeds for reaming, a simple rule of half the speed will work for most reaming operations. Using ...

Reaming holes - Coromant

To obtain the best results when using reamers it is essential to make them 'work'. It is a common fault to prepare holes for reaming with too little stock left. If insufficient stock is left in the hole before reaming, then the reamer will rub, quickly show wear and will result in loss of diameter. It is equally important for performance not to leave too much stock in the hole.

Getting reaming right | Cutting Tool Engineering

01.06.2010· The amount of stock remaining for reaming depends on hole quality and diameter. A rule of thumb is 0.010 " to 0.015 " should remain after drilling for reaming, except for small diameters, such as 1⁄32 ", which should have 0.003 " to 0.006 " of material for reaming, Lynberg noted. "A poorly drilled hole may need a little more material in order for the reamer to 'clean up' the hole walls," he said.
