Based on our own experience, this industrial grade drill bit is truly exceptional. Its construction is impressively robust and it effectively powers through even the toughest of materials. The only downside is that it may be a bit too pricey for those on a tight budget. Nevertheless, if you are looking for a top-performing drill bit, this one is definitely worth investing in.
Pros
High-quality materials ensure durability and longevity.
Bought to replace a cheap Harbor Freight Kit. Although significantly more expensive than others, they are very sharp, very straight, and very accurate. HF coated TINs are generally not very accurate and many are not straight, especially the smaller sizes. They cut very easily and generate very little heat.
Pros
60 pcs Premium High Speed Steel Heavy Duty Kit NAS 907B 135 Degree Split Point
Loved the beats! From 1 to 60, all very sharp, the label is stamped on the metal of the holder and the large miter angles on the bits. I immediately checked the 3rd largest bit and drilled the 1.25" VERY heavy steel driveshaft all the way through. Cardan bearings. One drop of 3 in 1 oil and this attachment cut like no one wanted. I made a mistake however and put the hole in the wrong part of the Shaft set so I had to drill another ANOTHER hole on the other end 1.5" curved steel with sex appeal!
