Drill Bit Industrial HSS 4.0MM 135Deg 1/Card

Professional-grade HSS drill bit engineered for demanding industrial applications. The 4.0mm diameter delivers precision drilling in steel, cast iron, and general-purpose materials. The 135-degree split point geometry reduces thrust force and prevents walking on hard surfaces, ensuring accurate hole placement and extended tool life. Heat-treated high-speed steel construction withstands high-temperature friction without dulling. Ideal for metalworking, fabrication, and maintenance tasks where reliability and performance matter. Single bit per card packaging for convenient storage and inventory management.
