Celebration time
time to get the word out!

CJT Durapoint 12.622 mm solid carbide twist drill with PM specialty flute and Premium Coatings cuts 2,000 automotive wheel hub inner parts (5 holes per part) where our competitors replaceable carbide head drill lasts only 500 parts.  CJT helped the customer reduce the cost to produce the hole by 60%.

The part is a steel forged wheel hub inner at 22 Rc hardness.

We also have had a very high degree of success with this construction of our tool on SC Durapoint twist and Kooltwist style tools in Crankshafts (Steel Forgings), Connecting Rods (Steel Forged and Powdered Metal), Wheel Hub Inners (Forged Steel) and Wheel Bearing Outers (Steel Forging).

Our Drills Outperformed
Competition Again

"We are delighted to hear the CJT sand drills outperformed the competitors carbide tipped drills by over 60% (24 average parts to their 15 parts) in the foundry sand casting vent hole hand drilling."

Buy American
     Burr Ridge, IL ----
Yellow ribbons and homecoming parades are great but, in my view, offer little of lasting benefit for our returning troops.

     What could benefit them and others in the military would be good jobs when they complete their military service.

     Those jobs might be available if more American bought "made in the USA" whenever possible.  To many Americans it's always the other guy's job that is in danger ---- until they end up in the unemployment line.

     Yes, wave the flags to welcome them home. But to really thank them, buy "made in the USA" products.
