Review: Worked like I wanted it to!!! - Broke exhaust manifold bolt in engine head. Did not want to remove head and take to machine shop to have it removed, so, used undersized drill to drill small enough hole and used this kit to remove broken bolt. First try....worked great!
Review: Screw Extractor Set - I recently picked up the Screw Extractor Set, 37# Cr-Mo & 6542 HSS S, and I’ve got to say, I’m thoroughly impressed with its performance. Here’s my breakdown of this toolset: Build Quality: The build quality of the Screw Extractor Set is exceptional. The set is made with 37# Cr-Mo (Chrome Molybdenum) steel and 6542 HSS (High-Speed Steel), both of which are highly durable materials. These materials are known for their strength and resistance to wear, which makes the extractors ideal for tough, stripped, or damaged screws. I feel confident that they will last a long time and withstand heavy use without breaking or wearing down. Ease of Use: Using the screw extractors is a breeze. The set comes with a range of sizes, which is great for tackling various screw types and sizes. The steps for use are simple: drill into the damaged screw with the corresponding extractor size and then reverse the direction to remove the screw. The design of the extractors helps grip even the most stubborn screws, and I didn’t experience any slippage during use.

### ⭐⭐⭐⭐ Product didn't work for me
*by H***Y on March 25, 2025*

But I got a refund. The manufacturer reached out and offered me my money back. I over torqued a bolt (55 ft lb instead of 52!) and it got stuck, snapped in half. This kit did nothing to it. It didn't bore a hole (yes I know it's left handed) and it didn't get purchase when I Did bore a hole using a different drill bit set. The company refunded me. How I got the bolt out was I got a big drill bit (way bigger than these) and I completely eviscerated the bolt from the inside. M10 13 mm head and 10.9. Took like a whole day to accomplish with breaks. Not an easy task. Not the maker's fault either. I'm sure it works sometimes.
