## Description

MACXCOIP Cobalt Drill Bit Set, M35 High Speed Steel Bits for Hardened Metals, Stainless Steel, Cast Iron and Wooden Plastics, with Metal Index Storage Box

Review: New favourite drill bit set - For so long I went with just whatever came with the drill. These bits are so hard, and with a little bit of oil cuts super well and stays sharp. Left hand is extra handy to drill out broken/welded in screws. Love them. Would bring them to bed if I were allowed.
Review: Decent, but don't expect reuse. - I used these bits to drill out a mild steel M4 bolt, then an M8 bolt. The M4 came out fine, then the M8 broke a bit because it had become so dull. I still have 1 more M8 to drill, but Imagine I will need to switch to a standard bit set to get started because of how dull these became.

### ⭐⭐⭐⭐⭐ New favourite drill bit set
*by C***I on 4 November 2024*

For so long I went with just whatever came with the drill. These bits are so hard, and with a little bit of oil cuts super well and stays sharp. Left hand is extra handy to drill out broken/welded in screws. Love them. Would bring them to bed if I were allowed.

### ⭐⭐⭐ Decent, but don't expect reuse.
*by D***. on 16 July 2026*

### ⭐⭐⭐⭐⭐ I rolled the dice if these would catch and back out a broken machine screw.. success!
*by D***. on 6 July 2025*

I had a use case where a machine screw had broken off in a location that wasn't easy to access. I decided versus pulling the piece of equipment apart to improve access, I'd spend the money on a set of these with the hopes it would catch as I was drilling out the broken off screw. The screw broke during installation, so I wasn't worried about rust or anything like that, and the roll of the dice paid off. As I slowly increased the size of the bits, one finally caught and backed it out. I replaced the machine screw with a new one and job done. This set saved me about an hour of disassembly and for me, that made the set worth the price. I don't know long-term how they'll hold up, but for me, these will be used infrequently and as I mentioned, they've already paid for themselves, so future use is just money in the bank. The case is nice and the quality seems good, so no regrets here.
