TOOL TIP<br />
Got LBS?<br />
Look For the Neck.<br />
Reducing tool deflection is a key part of<br />
successfully milling deep pockets and slots. Using<br />
an end mill with a necked-down shank and a<br />
stub or standard flute length greatly improves tool<br />
stability in long-reach cuts. The necked shank<br />
retains much of the core strength of the carbide<br />
rod, increasing tool life and achieving more<br />
precise milled wall tolerances.<br />
LBS, or Length Below Shank, designates the<br />
combined neck length plus the tool’s flute length.<br />
