I recently purchased this set and here is my review of the product. The coating on the drills is very uneven- it looks like it was painted on. Other 115 piece drill sets I've seen have the actual drill sizes conveniently seen on the case or an insert making selections easy, this one does not for all of the numbered and lettered drills. The case also has several compartments that are incorrectedly sized to securely hold the drill bits (#30-41 and 1/16, 5/64 and 3/32) on both ends. Drills #42 to #60 are only held on one end, though based on their small size that may be good enough. The product has \"SAE & Metric\" prominently shown on the outer packaging, yet I see no drill labeled with any metric sizes in the set. The price is the lowest I've ever seen for a 115 piece set.
