Metric Serrata Press Fit Drill Bushings are part serrated and known as SPM Type Serrated Bushings. The ‘SPM Type’ drill bushing is similar to the ‘PM Type’ bushing but for a part serrated OD. These bushings are designed to press into soft materials such as wood, plastics and soft metals. The top half of the bushing outside diameter is serrated to prevent rotational movement and increased axial resistance in the jig or fixture. The second half of the Serrata press fit bushing is finish ground for accurate and easy location and positioning.
The metric Serrata press fit drill bushing is available in 11 different OD sizes. These metric sizes range from 5mm to 26mm. There is a choice of 9 standard drill bushing lengths. These vary depending on the OD size and range from 6mm to 36mm. All bushings are hardened to 60-65 HRC for maximum life.
