ENA Boring Bar Sleeves - FAQ

​

Country of Origin: United States:

• Design.

• Materials.

• Manufacturing.

​

Why are ENA sleeves specific to particular holders?

• There is no industry standard for boring bar holders.

• Holder bore lengths and screw hole positions vary, and ENA sleeves are designed accordingly.

• With priority placed on ultimate performance, ENA sleeves are designed for uni-directional force flow: the holder and sleeve set screws are on the same side of the bar. This prevents opposing screw forces, and unlike conventional designs it prevents the bar and/or sleeve from riding on the set screws (bad) instead of on the sleeve/holder I.D. (good).  This also means that the sleeve's rear set screw position is determined by the holder's set screw pattern, to prevent any holder screw from mashing the sleeve's rear screw hole.

• We chose to design around the industry leader in scope, quality and availability: WTO.
