Works Works for me. I used them for pilot holes on steel frame of Suncast bar shed.I would drill part way rather than all the way in a single pass to avoid possible Overheating.Be cautious of metal “sawdust shavings” when using, standard for drilling in metals.
Basic cobalt bits that struggle with stainless steel and break easily under pressure The MACXCOIP 13‑Piece M35 High Speed Steel Cobalt Drill Bit Set looks solid in the listing, but in practice these bits are very basic and don’t perform well on tougher materials like stainless steel.WobbleThere’s a noticeable wobble when drilling, especially with the smaller bits. They don’t track straight, which makes precision work difficult.DrillabilityDespite being advertised for hardened metal and stainless steel, I couldn’t get through a 1/4” stainless steel plate even using a high‑power c
an excellent set of left-hand cobalt bits for snapped bolt extraction impressions following first, succesful, use.- bits are sharp and straight.- bits are capable of cutting deep into snapped stainless bolts without observable wear.tips:- the metal set case is tightly clipped together when closed and hard to open. instead of force, i've used a small pry tool.- drilling metal: i've started small, slow, then gradually ramped up speed and size - careful throughout.- reminder to drill "backwards" with left-hand bits.in the photo: the two bits that i've used to extract
nice product Good quality, sturdy drill bits for the price.
good quality Very impressive on its functionality. I purchased before Milwaukee and Dwall drills and they did not performed correctly, as a matter of fact, they got broke and it took kind of long to perform the drilling.With this MACKCPIP cobal drill bit set, i drilled like 5 holes with out any issue. Except for the smaller drill bit got broke, but the other one i used worked more then great!!!
Another one of those sets you don’t use often but… I use the MACXCOIP cobalt left hand drills to remove broken bolts, studs, and fasteners. They’re very hard so they are subject to breaking. Don’t use them too agressively or with a very high speed on metal. They seem to be good quality and very sharp. These are special purpose application only and should last.me for many years. The set came in a plastic index case to keep the jobber-length bits together and easy storage. Good value.
Work well in stainless steel Seem to be very good, solid case, great price
These bits are awesome!!! I bought a 10 pack because where I needed to use them, there was no store to buy replacements if it turned out these were junk. In the end, these (this) bit was as pleasant surprise.I drilled 30 holes in a steel I-beam with only needing a single bit and it still drills effectively without needing excessive force. The holes were drilled fast and easily with clean breakout on the backside.The drill bit cutting edge was does show some damage (see closeup image) after the 30 holes but it still dri
