SFM Metric Slip-Fixed Renewable Drill Bushings incorporate two features on one bushing. Used with liner bushings, Slip-Fixed Renewable Drill Bushings can be held in place by a lock screw, tenon or stop pin. The bushing is a slide fit in its corresponding liner, which allows for accurate alignment and easy replacement.
The removable fixed feature of the bushing is normally used in high production work. The bushing can be easily and quickly replaced with a minimum loss of production. The removable slip feature of the bush is used when more than one operation is carried out. Many drill sizes can be used with one bushing liner. The bushing is instantly removable after each operation. Both methods are designed to speed up operations and improve productivity. The knurled head allows for easy handling of the bushing to enable it to be rotated out of the removable slip feature.
