TJR® 4-10 mm HSS Co Spiral Drill Bit with Step Tip, 5-Piece Set - Durable and Heat Resistant, Perfect for Metal, Wood Plastic

PREMIUM HSSE COBALT MATERIAL Made of high quality high speed steel (HSS) with cobalt additive, these drill bits offer exceptional strength and durability. Cobalt provides higher temperature resistance and protects the drill bits from rapid wear and tear, even during intensive use. The material is ideal for demanding applications and guarantees a longer life of the drill bits, even when working with harder materials. Wide size range (4-10mm): The set contains 5 precision machined drill bits in the most common sizes (4mm, 5mm, 6mm, 8mm, 10mm) that are suitable for a variety of tasks. Whether for industrial applications or DIY projects, this versatile kit provides the flexibility you need to drill through different materials. These sizes are commonly required for repairs, renovations or specialized applications. STEP TIPS DESIGN The innovative step tip ensures precise centering and a clean bore without slipping. This technology allows the drills to operate with minimal pressure, resulting in a smoother and more accurate drilling result. The design is particularly advantageous when working on sliding or slippery surfaces. The step-by-step construction also provides improved chip removal and reduces friction, which reduces heat build-up. HEAT RESISTANT COATING Thanks to the special heat resistant coating, the drill bits stay sharp even at high speeds and heavy use. This coating protects the tips from excessive heat and ensures that the drill bits continue to maintain their effectiveness even on the toughest materials such as hardened steel, stainless steel and alloys. This means less frequent regrinding and improved performance over time. Wide Applications This kit is perfect for a wide range of materials and applications. It effortlessly drills through hardened steel, stainless steel, wood, plastic, aluminum and many other materials. Thanks to the robust construction, the set is ideal for professional use in workshops, on construction sites or for demanding DIY projects. Whether you're building furniture, repairing machinery or performing complex metalworking, this kit is the perfect choice for precise and efficient drilling jobs. trasl to tight
