Multi-layer Nh drills are suitable for drilling small diameter holes (0.8 to 10 mm) especially in glass and quartz, and within

certain limits also in ceramic material. Drilling depth is dependent on the drill diameter, and is between 7 and 22 mm;

other dimensions can also be supplied.

Nh drills are supplied with a cylindrical 4 mm shank, fitting the WINTER bench drill TIBO NB4. A collet chuck is required

for use of the WINTER flushing nozzle.

For drilling with a standard, fast-running drilling machine, insert the flushing nozzle into the spindle in place of the drill

chuck. The flushing nozzle has an internal thread at the bottom for mounting the collet chuck. Switch on water supply

before starting to drill, and switch off again only after drilling is finished.

Sharpening: If the drill bit becomes dull, it is advisable to sharpen by drilling into a WINTER Stone No. 2 or 5.
