What Customers Are Saying
Most customers praise these bits for sharp performance, clean drilling in wood and metal, and excellent value. However, many report sudden breakage under light pressure or in harder materials, with bits snapping or shattering unexpectedly—sometimes on first use. Some note brittleness in impact drills, while a few mention they lack strength compared to competing brands. Despite durability concerns for some users, those without breakage issues find them reliable and affordable, making them a worthwhile purchase for light to moderate tasks.

Masonry Bit

Drill bits that work as drill bits are supposed to
Would RecommendI like the fact that they drill holes as advertised.

Very brittle
Would Not RecommendThe bits are very brittle. Already broke both of them just drilling through studs. Also the aluminum base makes them wear quickly. If you use a magnetic angle head for getting into tight spaces the bit will fall out due to it having the aluminum base

Would Not RecommendSnapped after a few uses
From 9_SLASH_64-in Titanium Coated HSS Jobber Length Twist Drill Bit Verified Purchaser
All impact bits should be 2"
Would Recommend2" depth allows alignment pilot through standard 2x4(6,8...). If you need to use sheetrock anchors it helps if they're aligned properly. 1 Drill and install one anchor. 2 Attach board you want to mount. 3 Drill remaining (pilot) holes. 4 Remove board and install anchors. 5 Mount and attach board.

NO MORE Kobalt drills!
Would Not RecommendI've had too many of these Kobalt drill bits break under conditions when very little pressure is applied in soft wood and they are almost brand new. It's like they're made of glass.
Lack of inventory
Would Not RecommendI had to settle for this product because what I really needed was out of stock
