Produkbeskrywing
Engineered for Construction Materials: Designed specifically for drilling into concrete, brick, and stone, these bits combine YG8 alloy steel tips for hardness with 45# steel shanks for shock absorption. The heat treatment on smaller bits (4-6mm) ensures durability in abrasive materials.
Precision Sizing for Professional Applications: The graduated sizing (4-10mm) covers essential needs for electrical conduit holes, anchor installations, and plumbing pass-throughs. Each bit is black oxide finished and polished to resist corrosion.
Job-Site Ready Packaging: Housed in a sturdy plastic case with a printed size guide, this set keeps bits organized and protected. The shank diameters (3.3-9mm) are compatible with standard drill chucks for immediate use.
Durability Testing: Heat-treated bits (4-6mm) maintain cutting edges through extended use in reinforced concrete, while the larger bits (8-10mm) provide cost-effective performance for general construction drilling.
