Bit set for DBS-1 drill

This is a set of professional size drills M3-M10. These are very useful drills
that you can use for different types of materials. The cool thing about these
drills is that you only need to drill once to make a thread, which means you
save time and effort!

Here are the specs:

1. Drill sizes: M3 x 0.5mm (53mm long), M4 x 0.7mm (53mm long), M5 x 0.8mm
(55mm long), M6 x 1.0mm (55mm long) , M8 x 1.25mm (57mm long) , M10 x 1.5mm
(57mm long).
2. The drills are made of steel, especially the high-speed HSS type.
3. The design of the part of the drill called the “shank” is a 6-sided or
hexagonal shape (1/4′ bit), which is a common type of screwdriver.
4. You can use these drills for materials such as soft metals, aluminum sheets,
plastic, copper, steel, wood and more.

About the construction of drills:

1. Blade – The tip is extra sharp and strong, so it can easily drill through
hard materials.
2. Internal threading edge – this is the part that forms threads during
drilling.
3. Shank – This is the hex part that you attach to the drill.
4. External Tapping Edge – This part also helps to create threads during
drilling.

What you will get in this pack:

1. 6 taps (one each of M3, M4, M5, M6, M8, M10 sizes)
2. All of these are in their original packaging.

Just a note: no user manual is included, but these drills are pretty easy to use
if you’re familiar with using regular drills.
