Centre Drill : DT Online Recommendations
Centre Drills (aka Slocombe Drills) were designed to provide a location for a Tailstock Centre (hence their 60deg point angle) but are commonly used to make a small starting indentation to guide further drilling in a Lathe.
- If used only to start a drilled hole then one or two of the mid-range sizes will suffice since it is only the tip of the Centre Drill that will be used.
- Choose only those made from good quality High Speed Steel and offer them carefully up to the workpiece whilst it is rotating since the smaller sizes in particular, can break easily.
- Both larger and smaller sizes than the individual drills illustrated are available, but those shown will cover most work in Design and Technology.
- Model Engineers however, may wish to choose a set of the smaller sizes to suit to suit their more detailed precision work.
