SPI Diamond Scribe Pen

Description

Style 60, Included Angle: 60°, Refillable

The sharp diamond tip (and of surprisingly) high quality retracts with a push of the button top. The penstyle
design is manufactured to produce a wobble free "fit" between the outer barrel and the refill
holding the diamond. Use for preparing and marking samples to be examined by SEM and just plain
ordinary glass slides and photographic plates and also for scribing and trimming silicon, ceramics and
other hard materials. The high-precision "feel" has made the SPI diamond scribes very popular for high
volume and production work of all kinds.

Refill:

The SPI Diamond Scribe Refill has been designed for use with the SPI Diamond Scribe and may not fit other holders even though they appear to be the same in appearance. The refill consists of a diamond cutting point mounted in a tube having the appearance of a ball point pen refill. The tube is 105 mm long by 3 mm in diameter.


The standard product comes with a diamond 0.9mm (0.035") to 1.0mm (0.040") in diameter, with an
exposed angle of 90-100 degrees. The radius of curvature at the tip is on the order of 25.4 um (0.001")
to 50.8 um (0.002"). The SPI Diamond Scribe products are all made from natural diamond so since
nature never made two diamonds exactly the same, there with be some diamond to diamond variation
but we keep such variations within reasonably tight specifcations.
