The bits provide 5X life vs. competition. The bits are engineered using proprietary diffusion-bonding technology, which bonds carbide and steel at a molecular level. It’s a precise high-heat, high-pressure solid-state welding process that produces jobsite-proven bits. BOSCH is the only concrete bit manufacturer to make its own carbide, and 100% quality check on each and every single bit. The bit has a four-cutter design with 180° cutting diameter and 100% power transfer during drilling. The active-centering tip results in rounder hole, while the four 90° side angles create a wide and sharp head keep driving precise holes. The four-flute design aggressively pulls dust away from the work, for fast drilling and longer bit life.

Drilled through 60-year-old concrete quickly, as if it was wood.

Five miles of barbed wire fence to repair or replace. We have a lot of slab rock along the fence line that you cannot pound in metal T-Posts. We have been using the BOSCH HCFC5031 3/4 In. x 16 In. x 21 In bit to drill pilot hole in slab rook and then following up with a 1-1/2 In. bit. This has worked great and with over 50 holes drilled the bits are going strong. I highly recommend these bits.

I used this to drill about 20 holes and it was still looking good. I was impressed by the quality of the tool

I have received the 13†bit early AM, which was fantastic! Needed four holes for bolt anchors in my outside stucco wall in the backyard. Drilled first two holes really easily, the third hole had some obstruction 8†deep, I patiently waited for the obstruction to be drilled through to no avail. Pulled the bit out and discovered that the tip is … gone

High quality drill bit that met my needs for a super long bit. Expensive, but good.

Um, they didn’t pack this right and the tip was busted. Come on! Probably good quality but I’ll never know.
