Product Description
Milwaukee 1-1/4 in. x 18 in. MX4 SDS+ Carbide Drill Bit
Model Number: 48-20-7266
The Milwaukee 48-20-7266 is a 1-1/4 in. diameter x 16 in. flute length x 18 in. overall length MX4 SDS+ Carbide Drill Bit — the maximum extended-reach MX4 configuration at the large 1-1/4 in. diameter for the deepest structural penetrations and longest anchor embedments at this bore size requiring the SDS+ platform with four-cutter performance. The MX4 four-cutter tip delivers four active carbide cutting contacts per revolution for faster penetration and extended bit life in hard commercial concrete — at the very large 1-1/4 in. bore diameter, the four-cutter advantage is most significant as four contacts maintain drilling momentum through hard aggregate that would completely stall two-cutter progress at this massive bore size. The 18 in. overall length serves through-wall penetrations in the thickest structural concrete sections and the deepest structural anchor embedments specified for the highest pull-out load ratings at this large diameter.
At 1-1/4 in. large bore and 16 in. working depth, the SDS+ platform may reach the upper boundary of its effective energy delivery for the most demanding conditions — for the hardest high-strength commercial concrete at this very large diameter, the SDS Max platform provides higher impact energy that improves productivity. Milwaukee's MX4 flute geometry for this extreme diameter-length combination must manage the very high chip volume generated per revolution through the full extended working depth. The 1-1/4 in. diameter serves large structural anchors in the highest-capacity anchor systems for critical structural connections. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammers.
See Milwaukee's complete MX4 SDS+ catalog for all available 1-1/4 in. configurations and for SDS Max options for maximum energy at this large bore.
