🔩 Innovative HSS6542 Steel Spiral Groove Stainless - Unmatched Quality and Durability! Review

This product exceeded my expectations! I would also like to point out that it is extremely aggressive and fast when drilling holes. Please be careful with your hands, they will cut you very badly! Extremely hard material, the best bit I have ever bought! I'm over the moon with happiness! I highly recommend it!

Used today to pierce a 3/16 steel bumper (to mount hitch points). Using engine oil as a coolant and lower speed on a Dewalt brushless drill. I cut like butter. A hole was tested with the new 1/2 bit against the larger one in this set. The 1/2 bit took four times as long to go through the bumper and was less accurate than the stepped bit. Very impressed after about 6 exercises until I noticed dullness.

I have purchased several different brands of these step drills and most of them are very similar and like all others they wear out over time especially with excessive use. At first glance, they seem to easily gnaw through a tree. Not this one. I have to use a lot of pressure to get her through the raw diet. I don't know how well they work with metal, but personally I didn't give them much importance. I thought the different spiral cut would make the wood drilling more aggressive. That wasn't…
