M35 Cobalt Drill Bit Set, 13/19/25pcs
Made from M35 5% Cobalt HSS, these cobalt drill bits are ideal for processing hard materials, including stainless steel, cast iron, high-temperature alloy, titanium alloy, hard plastics, and woods.
The precise 135° split point prevents the bit from wandering.The 2-flute design helps to clear chips and debris away from the bit, reducing friction and heat for a faster, cooler drilling process.
Tips:
Because the speed of the electric drill is too fast, pay attention to the speed regulation when drilling (recommended speed: 100-1000r/min) The larger the diameter of the electric drill, the slower the speed requirement.

good

I needed to drill holes throughout my car trailer but the hardened steel won the drill bit battle with standard bits. I ordered these to show the trailer who the boss really is and the cobalt steel bits sliced through that steel like it was aluminum. Very happy.

Great

Needed these to drill some sheet metal. Used a DeWalt drill and some force. Needed to make a pilot hole first, then a larger hole. Both worked good. Good packaging and quick delivery

For how affordable these are they work well. Haven¡¯t broken any, have drilled through trailer frames and bumpers with this. By starting small and then using a bigger size it takes only about 30 seconds cutting through some thick steel.

I bought these to drill through 15mm thick steel (8cm/3 in density) and they cut great. I was really surprised at how good the bits were. I am very happy and surprised with them.

great tool drill bites

Slow and steady wins the race with these bits. I bought to drill holes through some stainless steel plates and it worked beautifully. Using these bits at high speed will not give you the results you are looking for, but with patience, these work exactly as you would expect. Quality product that is affordable.
