Exchangeable nosepiece drills are designed so that the entire front piece of the drill--a carbide nose--is removable and can be easily changed when worn (Fig 3).
In general, exchangeable nosepiece drills have some similarities with solid carbide drills--the hole depth capabilities tend to also be 7xD, the penetration rates are generally in the same range and coolant-through capability is highly desired (Fig 5).
Exchangeable nosepiece drills differ in that a steel body capable of holding a range of nosepiece diameters is used, as opposed to buying a specific drill for every hole size.
Hole quality with an exchangeable nosepiece drill is typically not quite to the level of that generated by solid carbide drills, but under ideal setup conditions the produced hole tolerances and surface quality can approach that of a solid carbide drill.
The three drill types reviewed above--solid carbide, exchangeable nosepiece, and indexable insert--are all typically supplied with coolant-through capability.
The nosepiece can be interchangeable and hold up to seven objectives.
Within the nosepiece is a 12.5-mm broadband blocking filter that passes only a safe amount of light for viewing with small apertures.
The rivet stem is inserted into the tool's nosepiece, the shank is placed through a predrilled hole, then the rivet tool handle is squeezed.
If it doesn't snap on the first pull, lower the nosepiece farther down the stem and squeeze again.

Behind the scenes, the Nikon software group uses the power of Windows macros to quickly integrate drivers for automating microscopy, including stages, nosepieces, and focus drives, enabling them to generate solutions and new applications rapidly and easily--a researcher's dream come true.
