Feature
●✅ COMPREHENSIVE SET: Contains 3 drill bits with a total of 29 sizes for versatile applications. 5 stage drill bits (4, 6, 8, 10, 12 mm), 9 levels drill bits (4, 6, 8, 10, 12, 14, 16, 20 mm) and 15 step drill bits (4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32 mm).
●✅ EFFICIENT DRILLING Double wing spiral groove design for improved performance and accuracy. The step drill bit set is used for drilling holes in a variety of materials such as steel or sheet steel, fine metal (thickness ≤ 5 mm), wood, fine iron, plastic, aluminum, PVC, fiberglass and other materials.
●Durable and robust: made of HSS-E M35 for high hardness, heat resistance and durability. The double flute spiral groove design on a step drill is a useful feature that can improve the efficiency, accuracy and performance of the drilling process. Easily identify the size you need with the high-contrast laser engraved size markings inside the spiral groove of the step drill.
●✅ FAST AND PRECISE: With up to 2x faster drilling speed, it allows you to drill 50% more holes per battery charge compared to the competition while keeping up to 4x longer than others.
●Industrial quality: HSS-E M35 is a type of high-speed steel that contains a certain proportion of cobalt. Cobalt is added to high-speed steel to increase its hardness, heat resistance and durability. The HSS-E M35 material possesses outstanding properties such as high toughness, wear resistance and high hardness at high temperatures, making it ideal for drilling hard materials such as stainless steel, alloy steel and titanium. HSS-E M35 drill bits can maintain their sharpness and cutting ability even at high temperatures and under high load, making them suitable for use in high speed drilling operations.
Description
drill essentials
High Speed Steel M35
HSS-E M35 is a type of high speed steel that contains a certain amount of cobalt. Cobalt is added to high speed steel to increase its hardness, heat resistance and durability. The material HSS-E M35 is characterised by superior properties such as high toughness, wear resistance and hot hardness, making it ideal for drilling hard material such as stainless steel, alloy steel and titanium. HSS-E M35 drill bits can maintain their sharpness and cutting ability even at high temperatures and under high load, making them suitable for use in high speed drilling applications.
Double-edged spiral design
The double-edged spiral design also allows for easy escape of material particles for a significantly cleaner drilling process. The service life of the drill is significantly extended.
Step Drill Sizes
- 15 step drill bits (4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32)
- 9 step drill bits (4, 6, 8, 10, 12, 14, 16, 18, 20)
