COMOWARE ドリルビットセット 60個 ジョバー長さドリルビット ワイヤーゲージ 1~60 ブラック&ゴールド仕上げ 135°スプリットポイント 高速度鋼 金属インデックス付き収納ケース

I’m very happy for that purchase 👍

Haven't actually used them yet but quality looks nice. Nice case. Great value compared to the napa $130 set.

Están muy frágiles las brocas para muchas rpm

Rather smaller than the indicated box.

First, you're not missing any bits. People are lazy and the case sucks so after shipping, you're going to have a bunch of the teeny bits stuck under the case 'shelves'. Dig around, they are all there. Accuracy to wire gauge size is decent. Definitely not perfect, but good enough for a budget set. Not a single bent bit either which is surprising because the case really does suck. That said, this is a budget set, get over it. I care about the bits, not the case. Bits all came sharp, inspected with loupe, saw no obvious defects in any of them. About 2/3 down the size chart, the bits switch from 135deg split to 118deg chisel, this should of course be expected. The bits hold up pretty well. I am not a machinist working 8hr days, but I've used this set for months in aluminum and steel and I've had no issues. Always using reasonable speeds and feeds, cutting lube and allowing for chip clearing. None have broken and I've used about a half dozen of my go-to tap drill sizes A LOT and they are still cutting solid. Can't complain one iota for the price.
