Engineered for Extreme Metal Drilling Power: Made from industrial-grade M35 steel with 5% cobalt, these professional drill bits are built to cut through tough materials—including stainless steel, hardened metals, and cast iron—with unmatched strength and durability. 135° Quick-Cut Points for Effortless Starts: Featuring Century’s precision 135° quick-cut tips, each bit is self-centering and requires less pressure to penetrate—eliminating the need for a center punch and preventing “walking” or “wandering” on contact. High Heat Resistance for Demanding Jobs: Designed to withstand high temperatures generated during metal drilling, these cobalt bits maintain their hardness and edge longer—ideal for power drills operating at 1,500 RPM or higher. Proudly Made in the U.S.A. for Pro Quality: Manufactured in the United States, this set reflects Century’s commitment to quality, performance, and reliability for tradespeople, machinists, and serious DIYers alike. Comprehensive 29-Piece Set for Maximum Versatility: Includes drill bits from 1/16" to 1/2" in 1/64" increments—conveniently housed in a labeled case for quick access and precise sizing in fabrication, automotive, or metalworking applications.
