About This Product
The MILWAUKEE® MX4™ 4-Cutter SDS MAX Rotary Hammer Drill Bits with solid head carbide deliver up to 5x longer life in concrete with rebar. Engineered with rebar guards to provide maximum durability in hard aggregate and rebar. Milwaukee designed their MX4™ 4-Cutter bits with sharp centering tips for exact spot drilling in concrete. The integrated 4-cutter design prevents lock-up in rebar, reducing downtime. Optimized flutes remove dust faster, reducing heat and delivering up to 15% more holes per battery charge. The wear mark indicator on each drill bit shows you when they no longer meet the ANSI requirement. These MILWAUKEE® MX4™ 4-Cutter Drill Bits are ideal for concrete with rebar and masonry applications.

Questions & Answers
Is this bit compatible with a standard power drill ?
No, the 3/16 in. x 6 in. 2-Cutter SDS-PLUS Carbide Drill Bit (48-20-8211) has an SDS-PLUS shank and is designed for use in SDS-PLUS rotary hammers, not a standard drill chuck.
Can it be used like an awl to mark where holes need to be drilled?
No. I would not recommend using it as an awl or punch. SDS-PLUS carbide bits are designed for drilling concrete and masonry, not for marking hole locations. Using the tip as a punch can damage the carbide cutting edges and reduce drilling performance.
You say it should work on concrete, brick, and block. Does block mean it should be able to drill holes into granite rock?
No — “block” means concrete block (CMU), not natural granite. The 5/8" SDS-PLUS 4-Cutter Bit is designed for concrete, brick, and masonry.
What size drill bit
The size is 1/2" diameter with 6" overall length; usable drilling depth is typically about 4".
You have said this needs an SDS plus drill chuck however it is an SDS max drill bit are the interchangeable.? with an SDS max rotary hammer drill will this go into a granite boulder?
Does this bit fit 1/2” drive hammer drills hilti,bocsh, Makita
This is an SDS Plus bit with indents on the shank specifically for use in SDS Rotary Hammers. For ordinary hammer drills use smooth or hex shank masonry bit. Check label on the tool which type you have. These bits are universal across brands.
Can this be used with a hammer drill with a 1/2 inch chuck?
You need an SDS-PLUS rotary hammer to use that 1" x 18" SDS-PLUS bit. It will not work in a hammer drill with a standard 1/2" chuck.
What drill bit do I need to drill a hole in a stump
Go with a self taping spade bit. 3/4"-1"-1 1/4"any of these are good. Back out bit to clear chips. Drill a few holes, not sure if you want to soak stump, salt stump or use store bought product. Whichever you want many holes
Hey Ruby. The Milwaukee 5/8" x 12" 4-Cutter SDS-PLUS Carbide Drill Bit is not the right choice for drilling a hole in a wood stump. Use a ship auger bit or spade bit (flat wood bit) for wood applications.
