Bit And Level Adjuster
It is frequently necessary to bore holes at certain angles. This can be done by using a bevel square, and holding it so one limb will show the boring angle. But this is difficult to do in many cases.
Fig. 266. Bit and Square level.
This tool has three pairs of V slots on its back edges. The shank of the bit will lie in these slots, as shown in Fig. 266, either vertically, or at an angle of 45 degrees, and boring can be done with the utmost accuracy. It may be attached to a Carpenter's square, thus making it an accurate plumb or level.
