Diamond Groove Drill Bushings (DG)

0 products

Diamond Groove (DG) drill bushings feature a unique knurled surface design, offering superior resistance to both axial and rotational forces compared to standard drill bushings. These bushings are securely embedded into holes using composite materials or resin, which flows into the grooves during the potting or casting process, ensuring a firm lock. Precision is key, as the inner diameter (ID) must be accurately positioned during installation, given the outer diameter (OD) is not ground. Ideal for guiding and supporting drill bits, reamers, countersinks, and counterbores, DG bushings enhance holemaking accuracy by preventing tool deflection, optimizing chip evacuation, and protecting the workpiece surface.
