A material removal rate is a measure of how much volume of material per unit time is being removed from a stock piece of material, typically on a milling or similar CNC machine.

Magnum drill bits use special Hi-Molybdenum tool steel and feature a 135° split point for fast penetration and accurate starting without a center punch. They withstand substantially higher drilling temperatures while maintaining sharpness. Body and clearance are gold surface treated for maximum lubricity. These rill bits are heat treated at 2185° F and then nitrocarburized at 950° to be measurably harder than high-speed steel.

Enter the radial depth of cut, axial depth of cut, and feed rate into the calculator to determine the material removal rate.

MaterialRemoval Rate formulafor drilling

CNC machines aim to have the highest possible material removal rate while continuing to produce accurate and precise parts.

To calculate material removal rate, multiply the radius depth of cut by the axial depth of cut, then multiply this result by the feed rate.
