About this item

  • Constructed from premium industrial-grade M35 cobalt high-speed steel and engineered with an advanced Titanium Aluminum Nitride (TiAlN) coating. This combination delivers superior surface hardness and exceptional heat resistance, providing up to 4X longer lifespan than standard HSS bits even in high-intensity applications.
  • Unlike traditional 2-flute or straight-flute bits, our precision 4-spiral flute structure ensures faster, smoother, and cleaner cuts. This design dramatically reduces friction and heat build-up while significantly accelerating chip removal, preventing the bit from walking or snapping during heavy-duty operation.
  • Features a standard 1/4-inch hex shank that universally fits power drills, impact drivers, and bench presses. The hex design securely locks into the drill chuck, eliminating bit slippage and ensuring maximum power transfer and user safety when drilling through stubborn materials.
  • Includes three essential step drill bits covering the most common hole sizes ranging from 1/8-inch to 7/8-inch. Each step is deeply laser-engraved for high contrast and wear resistance, allowing you to easily track your progress and stop exactly at your target hole diameter every time.
  • Engineered to punch through tough environments with ease. Effortlessly expands and cuts holes in thick stainless steel, sheet metal, cast iron, aluminum alloy, copper, fiberglass, and high-impact plastics. An essential unibit set for electricians, HVAC technicians, mechanics, and serious DIY enthusiasts.

FAQ

How can I confirm that a product is suitable for my application?


Review the product description, dimensions, materials, ratings, connection types, and compatibility information before ordering. Industrial requirements vary, so consult the equipment manufacturer or a qualified professional if you are uncertain.

Do you provide installation or technical advice?


We can help clarify information shown on a product page, but we do not provide engineering, installation, or workplace-safety advice. Products should be selected, installed, and operated by appropriately qualified personnel where required.

Can I change or cancel my order after placing it?


Contact us as soon as possible at ruleindgalein@gmail.com. We will try to accommodate your request, but changes or cancellations cannot be guaranteed once an order has entered processing or shipment.

When will my order be shipped?


Processing and delivery estimates may vary depending on the product, destination, inventory availability, and carrier. Please review the shipping information provided at checkout and our Shipping & Delivery Policy for additional details.

How can I track my order?


When tracking becomes available, it will be sent to the email address used for your order. Tracking activity may take some time to appear after the carrier receives the shipment.

Why did my order arrive in more than one package?


Items from the same order may be fulfilled or shipped separately. As a result, packages can arrive at different times and may have separate tracking numbers. You will not be charged additional shipping solely because an order is divided into multiple shipments.
