capacity but more durability, we should adjust a little more to the right (more graduation on

the bit).

In the case of a broken bit, without a cut to fit, the bit should be sharpened to a point shape.

Align the corners as close as possible to the adjustment lines and re-sharpen the drill bit

until a sharp edge appears, then adjust as above.

In order to work according to the properties of the material, the cutting angle must be

adjusted accordingly.

The most common cutting angles are 118º, 130º and 180º.

The angles are clearly marked on the pivot base of the prism. They can be easily adjusted by

opening the cam that holds the base.

The reversible prism has a drill bit range from 2 to 20 mm. To

insert and align the drill bit we must follow a few simple steps,

open the tool holder by means of the knurled screw provided for

this purpose, now we can insert the drill bit.

Keep the tip of the drill bit between 15 and 20 mm. Out of the tool

holder. Then close the clamp slightly by means of the knurled

screw, so that we can still turn the drill bit by hand. At this point

we should adjust the drill bit parallel to the two existing marks (A

for right-hand drills and B for left-hand drills).

Once the cut has been made, the clamp must be closed, do not

start sharpening unless the clamp is correctly closed.

By varying the basic setting shown, the rake angle can be varied

depending on the material to be drilled.

If it is required a larger cutting angle, with more cutting capacity,

then it should be adjusted a little more to the left (less graduation

on the tool holder). If we want less cutting angle, with less cutting
