These Bits are Beasts :)
Using these drill bits to drill through 8MM RSJ Beams, They are going through like a hot Knife through Butter. Cheaper ones were drilling 2 or 3 holes and then breaking/going dull. This thing though got through 22 Holes in an hour using a cordless drill, Went in Dry every time too, this thing didn't miss a beat. Highly recommend Makita Cobalt Bits :)

Bad - not up to the task
You buy cobalt drill bits from a known brand and expect quality - unfortunately that is not what you get here. Blunted and then essentially disintegrated after very little use much like a cheap HSS drill bit would. Poor show from Makita
