    Carbide-Tipped Drill Bits for Masonry and Concrete

    Crush rather than cut material so bits don’t jam or overheat while drilling masonry and concrete. The ultra-hard carbide tip breaks masonry into pieces and the widely spaced flutes channel them out of the hole. These bits stay sharp, resisting wear and heat that will dull or break other bits.

    Shank

    The shank has 12 splines for use with a spline-drive rotary hammer, which rotate and hammers bits simultaneously to penetrate material. Also known as percussion or impact bits.

    Changeable-Size Carbide-Tipped Core Drill Bits for Masonry and Concrete

    Instead of investing in multiple bits, change the bit body to drill a different-sized hole. These hollow bits remove a large core of material from concrete, brick, and masonry for installing pipe and conduit. The carbide tip resists wear and heat to stay sharp. Bits include a pilot drill to make starting holes easier.

    Style A

    Use the rotary-only mode for general purpose drilling and driving fasteners (requires a chuck adapter or a magnetic bit holder). In rotary-percussion mode, the tool provides both a rotary drilling and hammering action. In the percussion-only mode, the tool provides only the hammering action. Use this mode when working with chisels and other masonry tools (see Chisels for Rotary Hammers). All have a variable speed motor—the further you depress the trigger, the faster the drill rotates.
    For Spline Bit Shanks—Designed to drill larger holes than a SDS-Plus hammer, these models use spline-shank drill bits (see Spline-Shank Masonry Drill Bits and Spline-Shank Masonry Core Drill Bits). A powerful and durable hammer mechanism lets you drill deeper, larger holes in masonry and concrete in less time than with hammer drills.
    12 Chisel Lock Positions—A chisel lock allows you to choose from 12 or 36 chisel positions to match the angle of many surfaces.
    Built-In Safety Clutch—A built-in safety clutch protects you and the hammer if the bit gets stuck in your material.
    Vibration Reduction—These rotary hammers have a vibration reduction system for increased user comfort, provides smooth starts, and won't slow down as you drill deeper.
