Square Flute Compression / Depression design provides better dust removal thus faster drilling. Head geometry design also helps prevent locking when hitting rebar on the side. Bit is specially designed for longer life when drilling in concrete. As an additional benefit, it can crush through and pulverize rebar when drilling in reinforced concrete applications.
The reinforced flute geometry uniformly distributes the dust through the flute for even flute wear. The reinforced geometry also reduces vibrations and transfer more energy from the powertool motor to the tip of the drill bit making for a smoother and more efficient experience.
All available in 25 pcs, except for 5/8" x 6" x 4" which has 12 pcs.
