Product Description
Milwaukee 3/16 in. x 10 in. MX4 SDS+ Carbide Drill Bit
Model Number: 48-20-7313
The Milwaukee 48-20-7313 is a 3/16 in. diameter x 8 in. flute length x 10 in. overall length MX4 SDS+ Carbide Drill Bit — the standard extended-reach MX4 configuration at the small 3/16 in. anchor diameter for CMU through-wall penetrations and deeper anchor embedments. The MX4 four-cutter tip delivers four active carbide cutting contacts per revolution versus the two-cutter standard of conventional SDS+ bits, providing faster penetration rate and extended bit life from doubled carbide wear distribution. At the 3/16 in. diameter's small bore, the MX4's four-cutter advantage is particularly significant in hard commercial concrete where the small cutting face meets high aggregate resistance — four cutting contacts maintain drilling momentum through hard aggregate that would stall a two-cutter bit's progress more noticeably at this small size.
The 10 in. overall length with 8 in. flute enables through-wall drilling in standard CMU block with finish material, longer concrete screw anchor pilot holes where engineering specifications require deeper embedment for higher pull-out load ratings, and drilling positions where adjacent structure prevents placing the hammer close to the work surface. Milwaukee's optimized flute pitch for this small-bore extended configuration maintains effective debris evacuation through the full 8 in. working depth without choking — critical for maintaining production drilling pace at this diameter-depth combination in sustained commercial anchor installation work. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammers.
