Ratings & Reviews for Kobalt 21 -Piece Assorted Assorted Titanium coated HSS Jobber length Twist Drill Bit Set
Ratings may include incentivized customer reviews.
What Customers Are Saying
Customers praise the wide variety of bit sizes and well-designed storage case that keeps bits organized and easy to find. Many report the bits perform well, drilling through steel efficiently and offering excellent value for the price. However, a substantial number experience premature bit breakage, describing the metal as brittle and weak, with some bits snapping on first use or failing like "a twig in the wall." Several compare durability unfavorably to older brands. Despite these concerns, most customers find the set worthwhile for casual DIY projects, though durability remains a persistent issue.

Not worth buying! 1st two bits broke quickly. Taught mechanics for nearly 40 years. Know how quality drill bits should function. Good quality bits don’t shatter at slow speeds under little pressure. Appeared to be defective

Do not use for metal unless it is thin metal.
Would Not RecommendI broke three (3) of the first shelf bits immediately when I used them (not the small bits).

Oversized Case - Bad!
Would Not RecommendWhy is this case so large? For 14 drill bits, two rows of 7, the case comes with this is extremely thick/deep. It takes up way too much room and anyone's tool bag. What is the point of this?? Kobalt not wanting to design another case style?

Bits are fine. Case is worthless.
Would Not RecommendLike most of the Cobalt stuff I've purchased from Lowe's, the drill bits in this package are pretty good quality. They've worked well in both wood and metal and do a nice job penetrating without marring and exiting without damage. They show little sign of being any worse for wear despite the repeated use they've had since I bought them. The 2 Star rating comes largely from the frustration that Cobalt can't seem to design any case for the multi-packs of anything that actually keeps the items wher...

Junk
Would Not RecommendBroke 4 of these yesterday and bent a 5th drilling into a relatively thin piece of metal. Will not buy these ever again.
Don’t buy. Go with a premium brand.
Would Not RecommendThese are junk. They actually break off.

Garbage - do not buy
Would Not RecommendLike others, I've had many of these snap - so far 5 of the 21 have snapped on me while using them. Also like others have noted, they don't stay in their holder, and easily fall out of their holes and become a game of 21 (minus five so far broken) pickup My 5-8 year old Dewalt set never broke, they just got dull after so much use. Kobalt makes some fair tools, and the overall rating on these were pretty good. I regret the purchase.
Good drills
Would RecommendJust bought, used once, they drill metal, at first glance, excellent drills
