FOR IMMEDIATE RELEASE


ALLIS-CHALMERS CORPORATION REPORTS
THIRD QUARTER 2004 EARNINGS

HOUSTON, TEXAS, November 12, 2004 - Allis-Chalmers Corporation (Amex:ALY) today
announced its results for the third quarter ended September 30, 2004. Revenues
increased to $11.9 million for the third quarter of 2004, an increase of 47.0 %
from revenues of $8.1 million for the third quarter of 2003. Net income for the
third quarter of 2004 attributed to common shares was $576,000 or $0.04 per
share (diluted), compared to net income attributed to common shares of $1.0
million or $0.16 per share (diluted), which included a one-time $1.0 million
gain from the settlement of a law suit, for the third quarter of 2003.

The Company reported revenues of $33.0 million for the first nine months of
2004, an increase of 47.1% compared to revenues of $22.4 million for the first
nine months of 2003. Net income for the first nine months of 2004 attributed to
common shares was $1.5 million, or $0.15 per share (diluted), compared to net
income attributed to common shares of $281,000 or $0.04 per share (diluted),
which included a one-time $1.0 million gain from the settlement of a lawsuit,
for the first nine months of 2003.

The Company announced that revenues and operating results improved for the third
quarter and first nine months of 2004, compared to the 2003 periods, primarily
due to the general increase in oil and gas drilling activity. Revenues and
operating results increased most significantly at its directional drilling
services segment due to increased activity as well as the addition of operations
and sales personnel which resulted in increased capacity and market presence.
The nine-month period ended September 30, 2004 was also impacted by the
inclusion of the operations of AirComp LLC, the Company's 55%-owned compressed
air drilling joint venture for the entire nine month period. AirComp was formed
in July 2003.

Munawar H. Hidayatallah, the Company's Chairman and Chief Executive Officer
stated, "We are very pleased with the continued growth of our company. During
the quarter we also took major steps to improve our capital structure and
increase our ability to grow. As previously announced, during the quarter we
completed two private placements of our common stock aggregating $16.3 million,
and in September our shares began trading on the American Stock Exchange. In
addition, we acquired Safco in September and acquired Diamond Air Drilling in
November 2004, which we anticipate will make significant contributions to our
future growth.
