PROVISIONAL SPECIFICATION.
An Improved Boring Tool suitable for Dental Purposes.
I, ISIDOR BEUTELROCK, Dentist, of 12/3, Kaufingerstrasse, Munich, in the
Empire of Germany, do hereby declare the nature of this invention to be as
follows:
-
Drills or borers hitherto used for dental purposes are turned of steel and then
hardened.
Such borers or drills are difficult to make and the quality and form do not
yet correspond with the requirements of the dentists as they have the following
disadvantages.
1. They break easily.
2. The drills chip off and the pieces thereof are deposited in the bore head
whereby it is necessary to clean the same often.
These disadvantages are completely avoided by this invention which relates
to a drill or borer formed of a flat piece of steel or other suitable material which
is twisted in a spiral or helical form and tapers towards its point. It is provided
with a cutting edge and sharp point. Like previous drills or borers it is pro-
vided with a handle and the same is inserted into the boring machine. In an
equally favorable manner this instrument can be used not only as a borer or
drills but also for cleaning and disinfecting the hollows in the tooth with the
aid of cotton wool. As by its peculiar form it is specially adapted for retaining
or manipulating the wool.
On account of the spiral form of the instrument it can have sufficient elasticity
combined with resistance and strength to resist breakage or chipping.
Dated this 25th day of March 1898.

2. The drills chip off and the pieces thereof are deposited in the bore head
whereby it is necessary to clean the same often.
These disadvantages are completely avoided by this invention which relates
to a drill or borer formed of a flat piece of steel or other suitable material which
is twisted in a spiral or helical form and tapers towards its point as shown on
different scales in Figs. 1 and 2 of the annexed drawings. It is provided
with a cutting edge and sharp point. Like previous drills or borers it is pro-
vided with a handle and the same is inserted into the boring machine. In an
equally favourable manner this instrument can be used not only as a borer or
drill but also for cleaning and disinfecting the hollows in the tooth with the

:
On account of the spiral form of the instrument it can have sufficient elasticity
combined with resistance and strength to resist breakage or chipping.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
The improved boring tool or drill formed of a flat piece of steel or other suit-
able material tapered towards its point and twisted in a spiral or helical form
provided with a cutting edge and sharp point substantially for the purposes
described and illustrated.
