Hi Jeff,

Just wanted to let you know how happy we are with the Rosina kit. I can't believe how precise the plate is. I drilled the broken turbo bolt out and could just about see all the threads!

I almost didn't even need to use the tap. The Rosina plate makes drilling very quick and straight forward procedure. Being able to call for great advice is invaluable. You guys make awesome products and provide great service after the purchase.

Hi Jeff,

Just wanted to tell you and your team for making awesome tools and make the job easier. Had a 6.8l with four broken studs inset about an 1/8 inch . The Rocky II200 worked great! Three came out with just drilling with the SSSC125 and the fourth one didn't want to move but with the Rocky II200, I just step up to the next two size bushing and drill out and it is right on the money. Ran the ProMAXX® PPT008 tap in and done!
Thanks for a awesome tool

I received the "rocky" tool very quickly, then proceeded to watch videos and read instructions. This tool is a beautiful thing,

I have a 1999 ford 250 super duty with a v-10. All but three studs on left side were broken off about 1/4 inch remaining. No problem drilling perfectly straight with this tool, Tool extractors were breaking as fast as I could purchase them.

Jeff created a custom kit for a v-10 ford, and approximately three hours later, all studs were removed.[ without damaged threads]. the only small problem was tapping remaining threads out of holes, I just slowed down and took my time and they came right out.

This saved me countless hours of valuable time.

Thank You for a valuable tool for my collection I will recommend this for anyone repairing exhaust manifolds

These drill plates are the greatest thing. Done many Ford 4.6, 5.4, 6.8 gas engines and 6.0 6.4 diesel. Had you shipping up the plate for the dodge Ram and the 5 studs in this head came right out.

I can not get over how the drill bit drill there the fastest ones I have ever seen. I also use the drill bit on my HO Model Locomotives to install ditch lights and floor light. The locomotive frames are hard and just eats up Home Depot drill bit..

The drill bits cut very nice and very clean. Very very important. Keep up the great work

Testimonial on the ease of using one of the ProMaxx tools for removing broken studs from a Ford F350

The tool functioned as it was supposed to. It was still a long process on this particular truck. Every stud fought us tooth and nail. But the five that needed to be drilled and extracted did come out thanks to the Promaxx kit.

I will definitely recommend it to anybody struggling with this very common problem in our repair world.

Keep up the good work and thanks for going above and beyond by taking my call after your regular hours and getting it out next day ups well after your normal pick up time.

Subject: Worth every penny!!

This tool is an investment in time and money, my tech literally spent half the time as normal. He is smiling and so am I. Can't say enough about the company. What a pleasure to deal with, even got a one on one tutorial for my tech before he used it. Thanks again,

Jeff ,
Thanks for getting the rocky tool out to us next day my tech had 4 broken studs out in about 1 1/2 hrs verses the 3 or 4 it would have probably taken him normally . This tool we pay for itself in just a few jobs.

This product has increased the turnaround time for exhaust manifold jobs substantially. It takes the guess work of hole location and depth out of the equation, reducing overall time by almost half.  After trying all the competitors drill bits I have not been able to find a single one that remotely compares to the ones produced and sold by Promaxx they are now my go to drill bit for every drilling job.

"I can't say enough about how much help this product has been to help me make more hours and how it's helped increase my productivity". I have been working at ford dealerships for the past 6 years and have had to deal with numerous exhaust manifold jobs with countless broken studs.

Before I would take hours attempting to either weld to the stud or freehand drill and extract the stud. My snap-on guy told me he had a tool that was guaranteed to cut my extraction time dramatically and with being a flat rate tech that's money in the bank, so I said well its worth the shot. I bought your product for the ford manifold stud extraction and I must say what used to take hours now is a mere 10-15 minutes.

I can't say enough about how much help this product has been to help me make more hours and how it's helped increase my productivity.

Thank you for making such a helpful tool!!!
