“ MECO ”

Hammer Drill

The rapidity with which this little tool
drills into coal or stone of medium con-
sistency is one of its features. This is
owing to the patent Flap Valve which
is the most flexible on the market,
and which does not deteriorate but
improves with use. This drill will bore
a 4 ft. hole in coal in one minute.

In the manufacture of the “Meco ” only
the best forged steel is used ; wearing
parts being specially hardened and
ground to gauge. This form of con-
struction results in a tool which is un-
surpassed for durability and low spare
part cost.

The “Meco” is made in 3 sizes, the largest of
which drills holes up to 20 ft. deep.
