grade HSS M2 drill bit, cobaltcoated, reduced shank — 13 mm to 15 mm sizes for reliable, precise drilling Key benefits Durable construction: Made from grade HSS M2 for long life and consistent cutting performance. Improved hardness and heat resistance: Cobalt coating increases wear resistance and maintains edge strength under heat, reducing bit wear during heavy use. Precision results: Sharp geometry and robust material deliver clean, accurate holes even in demanding conditions. Broad compatibility: Reduced shank design fits standard drill chucks, making the bit compatible with most handheld and benchtop power drills. Practical size range: Sizes from 13 mm to 15 mm cover common hole requirements without changing tools. What this solves Reduces downtime and tool changes by providing a durable bit that resists heat and wear during extended drilling. Ensures consistent hole quality for repeatable assemblies and installations. Simplifies tool setup by fitting standard chucks without special adapters. Key specifications Material: HSS M2 Coating: Cobalt (increases hardness and heat resistance) Size range: 13 mm to 15 mm Shank type: Reduced shank for standard drill chucks Typical applications Professional metalwork and fabrication where reliable, heatresistant drilling is required. Onsite construction and maintenance for drilling in structural components and fittings. Workshop projects and repairs that need consistent hole sizes between 13 mm and 15 mm. User notes The reduced shank lets you use the bit in most common drill chucks; ensure the drill and chuck are rated for the bit size before use. Use appropriate cutting speeds, lubrication, and clamping for life and accuracy. Reliable choice for professionals and hobbyists who need a tough, precision drill bit in the 13–15 mm range that fits standard power tools.
