SDS Plus 4CT MX4™ 9/16" X 10" X 12"

The Milwaukee 48-20-7384 is an MX4 4-cutter SDS Plus bit, 9/16" in diameter, with 10" of drilling depth and a 12" overall length. It has a solid carbide head, it is made for concrete with rebar and other masonry, and it fits any SDS Plus rotary hammer.

Why it's built this way

• The solid carbide head is rated by Milwaukee to last as much as five times longer when drilling rebar-reinforced concrete.
• Four cutting edges keep the bit from locking up when it meets rebar, so you lose less time.
• Rebar guards shield the head in hard aggregate and steel.
• A sharp centering tip starts the hole right on your mark, in concrete or through metal decking.
• Variable flutes clear dust quickly and keep heat down; Milwaukee claims as many as 20% more holes on each battery.
• Built to ANSI B212.15 so holes come out sized for common anchors, with a wear mark that shows when the bit falls below that standard.

Is this the right one for you?

Choose the MX4 when rebar is a regular part of the job or when you drill through metal decking. For lighter work in general concrete, Milwaukee's M/2 2-cutter SDS Plus bits are the other option. Make sure your hammer takes SDS Plus; this bit will not fit an SDS Max hammer or a standard drill chuck. The 10" drilling depth covers deep anchor holes and holes through thicker walls and slabs. Replace the bit once the wear mark shows it is under ANSI size.
