DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the configuration of an embodiment of the present invention. As shown in FIG. 1, in the casing 2 of the drill 1, horizontal or vertical levelers 7 and 8 are attached to the portions 5 and 6 parallel or vertical to the central axis 4 of the blade 3. The horizontal or vertical levelers 7 and 8 are bubble tubes 7a,
8a.

2A and 2B are horizontal bubble tubes 7a.
2 is a vertical and horizontal cross-sectional view showing a liquid 11 enclosed in a container 10 made of an elongated plastic having a scale 13 whose upper surface bulges so that bubbles 12 can be formed. 3 (a) and 3 (b) are vertical and horizontal cross-sectional views of the vertical bubble tube 8a, which is made of a disk-shaped (round plate type, square plate type) plastic with a graduated scale 23 on its upper surface. Container 20
The liquid 21 is enclosed so that bubbles 22 are formed therein.

As the horizontal or vertical levelers 7 and 8, there are various types such as a floating type, a gravity type, and a mixed type thereof in addition to the bubble type. The shape of the container includes various shapes such as a round plate shape, a square plate shape, a spherical shape, and an egg shape, and it is preferable that the scale portion has a lens function. Ball-shaped and egg-shaped can be used as a horizontal and vertical level. A protective cover should be attached to them.

To use this, the worker must use the levelers 7, 8
If the processing operation is performed while looking at the scale 13 or 23, the processing operation can be performed accurately. When making a horizontal hole, look at the scale 13 of the horizontal bubble tube 7a, and when making a vertical hole, look at the scale 23 of the vertical bubble tube 8a.

With the above apparatus, one person can perform accurate work, and the work time can be shortened. Further, since the hole can be accurately drilled, the tap is less likely to break, the correct screw thread can be correctly formed, and the tightening force of the screw is improved. The core drill diameter can be small during core drilling (diamond drilling) in construction work, which allows for faster work and lower costs.

In order to attach the horizontal or vertical levelers 7 and 8 to the casing 2 of the drill 1, ordinary screws, adhesives,
Although bolts, magnets, etc. are used, the present invention can be applied to existing drills by attaching them detachably, which is effective.

FIGS. 4, 5 and 6 show such an example.
Is an iron plate 31 in which the levelers 7 and 8 are fixed to the magnet 30 and the housing 2.
5 is attached with the Velcro 32.
