4.0mm HSS Drill Bit with 5% Cobalt – High-Speed Steel Drill Bit for Wood, Metal & Soft Metals
Product Overview:
This M35 High-Speed Steel Drill Bit with 5% Cobalt is designed to handle even the toughest materials with ease. Whether you're working with wood, softer metals, or alloys, this drill bit is built to last. Its combination of high-speed steel (HSS) and cobalt ensures superior performance under high temperatures, giving you an edge in precision and durability that standard drill bits simply can’t match. Ideal for both professionals and DIY enthusiasts, it offers exceptional value and efficiency for all your drilling needs.
Why Choose This 4.0mm HSS Drill Bit with 5% Cobalt?
Unmatched Durability: The addition of 5% Cobalt to the High-Speed Steel makes this drill bit more heat-resistant and durable than regular HSS drill bits. The cobalt’s red hardness allows the bit to perform efficiently in high-heat applications, making it ideal for tougher materials that would typically cause premature wear on regular drill bits.
Versatility Across Materials: This drill bit excels in drilling through a wide variety of materials, including hard plastic, cast iron, alloys, stainless steel, wood, and softer metals such as aluminum and brass. It is especially useful for drilling through both ferrous and non-ferrous metals, as well as wood for cabinetry, furniture, and DIY projects.
Improved Cutting Efficiency: The 135° split point design allows for self-centering and faster penetration, reducing the need for excessive pressure while drilling. This ensures that the bit cuts smoothly through materials with minimal effort, helping you achieve clean and accurate holes every time.
Key Features:
Material Composition: Manufactured from High-Speed Steel (HSS) with 5% Cobalt, ensuring superior heat resistance and longer tool life even during prolonged use or under high-heat conditions.
Quick-Cut Design: The 135° self-centering split point ensures that the bit starts drilling immediately, preventing slipping and providing smoother, faster cuts with less applied pressure.
Professional Grade: Perfect for professional-grade work as well as home improvement projects. From woodworking to metalworking, this drill bit is engineered to handle the rigors of heavy-duty applications.
Compatible with Most Drill Chucks: Works well with both keyed and keyless chucks, making it versatile for various drilling tools and machinery.
