3/8 Inch x 12 Inch SDS Plus Rotary Hammer Drill Bit, Carbide Tipped for Brick, Stone, and Concrete Version 2 (3/8" x 10" x 12")

I bought a few of these bits at once expecting to burn through them or for them to snap. I'm still on the first bit and it's been used several times per day at the full 12 inch length and is still in good condition. Would recommend this bit.

Had to drill thru outside brick wall and 6’’ basement concrete wall. Took a few minutes, no issues.

Bueno

I bought this to rehang an aluminum awning that fell off a friends house. It worked great to rehang the awning with 1/4 tapcons. The longer length made it a much easier job because I didn’t have to stretch all that much. I really like the plastic tube that it comes with too. Keeps it secured and I don’t have to guess at what bit I’m grabbing bcos it’s labeled 3/16ths. I would buy it again

I use this all the time and it has held up great

Bad ass drill bit! Half price from box stores.

Worked on concrete as it should

Worked great to drill a 1/4 in hole through my basement concrete block wall! Cut through it like butter and was plenty long enough. Very good value for the money.
