Press-Fit Oil-Groove Bushings – Type 2 (P, PM)

Drill Bushings

Product Information

Type 2 – With Oil Hole & External Groove

Oil grooves are specially designed coolant passageways in a bushing's ID wall. Oil grooves are available on almost any bushing type, including press fit, head press fit, and renewable. Use when you need complete drill lubrication and cooling, such as when drilling hardened steel, or when bushings are used as bearings.

The Type 2 oil groove shown here is our most popular. The OD groove allows coolant to flow around the bushing, then through the radial hole in the bushing's wall, to the internal oil grooves. This allows installing the bushing at any orientation, and mounting several bushings in series using a single manifold passage.
