This Milwaukee SDS-Plus drill bit set includes 10 popular sizes from 5-12mm, perfect for a wide range of drilling applications in concrete, masonry, and more. The drill bits are made from high-quality M2 steel for long-lasting performance and feature a reinforced flute design for optimal dust removal, greater durability, and fewer breakages. Key features include breaker points for a "demolition" effect that creates micro cracks for up to 25% faster drilling, a centering tip for precise spot drilling and preventing slipping, enlarged rebar chamfers to protect the tip from rebar damage, and a tapered shoulder design to reduce friction for better speed and efficiency, especially with cordless hammers. The set comes with 2x 5mm x 110mm, 2x 6mm x 110mm, 2x 6mm x 160mm, 2x 8mm x 160mm, 1x 10mm x 160mm, and 1x 12mm x 160mm drill bits, all housed in a plastic cassette case.
