Century Drill & Tool 26121 Pro Grade Cobalt Drill Bit Set, 21 Piece

• 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 21-Piece Set for Metalworking Versatility: Includes 21 drill bits sized from 1/16" to 3/8" in 1/64" increments, all housed in a convenient storage case with clearly marked sizes for fast access and organized tool management.
