Multi-Surface Drill & Screwdriver Bit Set (19 Pieces)

Description

TOTAL 19 pieces drill bits & screwdriver bits set (TACSDB1901)

TOTAL TACSDB1901 is an all-in-one industrial-grade accessory kit engineered to handle drilling and fastening across a massive array of materials—including low-carbon steels, alloyed metals, concrete, solid brick, plastics, and dense timber. Designed for service vans, maintenance-and-repair (MRO) teams, and general contractors, this comprehensive 19-piece set ensures you always have the correct bit on hand for rapid field installation and assembly work.

Engineered Material Specialization

• HSS Rolling Twist Drill Bits: Forged from high-speed steel with precision rolled flutes, these bits deliver rapid metal penetration, aggressive chip clearance, and excellent thermal dissipation when boring into steel, copper, iron, and sheet metals
• High-Impact Masonry Bits: Equipped with ultra-hard, localized cutting tips engineered to withstand the punishing physical concussions of impact and hammer drills when anchoring into masonry, blocks, and concrete
• Industrial 25mm Fastening Bits: Machined to strict dimensional tolerances to ensure a flush, snug fit inside the fastener head, drastically minimizing cam-out (slipping) and saving hardware from stripping out under load
