Product Description
Milwaukee SDS+ 4-Cutter Bit 1 in. x 10 in.
Model Number: 48-20-7240
The Milwaukee 48-20-7240 is an SDS+ rotary hammer drill bit in 1 in. diameter with a 10 in. overall length featuring a 4-cutter carbide tip — a large-bore extended-reach configuration with Milwaukee's four-cutter tip geometry for maximum drilling performance in the hardest commercial concrete at the 1 in. diameter. The four-cutter tip provides four active carbide cutting contacts per revolution versus the standard two-cutter, delivering faster penetration rate and extended bit life by distributing cumulative carbide wear across twice the surface area per revolution. At the 1 in. large bore diameter in hard commercial concrete, the four-cutter advantage is most significant — four cutting contacts maintain drilling momentum through the hardest aggregate that would slow a two-cutter bit's progress noticeably at this large diameter where the cutting face area and resistance are substantially higher than at smaller anchor sizes.
The 10 in. overall length provides working reach for thick structural wall penetrations and deeper anchor embedments requiring more depth than the standard shorter configuration provides. The 1 in. diameter serves structural anchors in heavy-duty anchor systems for critical connections, through-penetrations for 3/4 in. conduit and large wire bundles, and major mechanical rough-in work requiring this maximum standard SDS+ bore. Milwaukee's flute geometry for this diameter-length combination maintains adequate chip transport from the working depth throughout sustained drilling. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammers.
