This 18mm Loops Blacksmiths Drill Bit is designed for professionals and serious DIYers tackling large-diameter holes in a variety of tough materials like steel, aluminum, plastic, and wood. Its high-speed steel construction ensures durability and efficient cutting, but its reduced shank may require specific chucks for optimal grip. This guide covers its features, performance, and best practices for effective use.

This drill bit is suitable for a wide range of materials including aluminum, steel, plastics, wood, and various non-ferrous metals.
A reduced shank means the diameter of the drill bit's shaft (shank) is smaller than its cutting diameter. This allows a larger diameter bit to be used with drills that have smaller chuck capacities.
No, standard drill chucks will work, but ensure your chuck can securely grip the reduced shank. For best results and safety with an 18mm bit, a drill press is recommended.
Use appropriate drilling speeds for the material, apply cutting fluid or coolant when drilling metals, and avoid excessive pressure. Allow the bit to cool between holes if necessary.
Clean off debris with a wire brush after each use. Apply a light coat of oil to prevent rust and store in a dry place.
While it's high-speed steel and durable, extremely hardened steels may require specialized bits or slower speeds and more aggressive cooling. Test in an inconspicuous area first.
The 'PRO range' designation typically signifies that the product is manufactured to higher standards, offering improved durability, performance, and longevity for professional or demanding applications.
Ensure the drill chuck jaws are tightened firmly onto the reduced shank. If slippage persists, consider a drill with a larger chuck capacity or a specialized chuck adapter. Use a drill press for maximum stability.
Reduce drilling speed and apply cutting fluid or coolant, especially when drilling metal. Allow the bit to cool periodically. Ensure adequate lubrication when drilling wood to prevent scorching.
Verify correct drill speed for the material. Ensure the bit is sharp. For wood, try drilling partially from one side and finishing from the other. For metals, use a cutting fluid.
Do not force the drill bit. Apply steady, consistent pressure. Ensure you are using the correct speed and feed rate for the material. Check for any binding or misalignment.
Setup: Insert the reduced shank end of the drill bit into your drill's chuck. Ensure the chuck jaws grip the shank securely and are tightened appropriately. For precise, straight holes, especially with the 18mm diameter, mounting the drill in a drill press is highly recommended. Select an appropriate rotational speed for the material being drilled – slower speeds for harder metals and faster speeds for softer materials like wood or plastic.
Compatibility: This 18mm drill bit features a reduced shank. This means its shank diameter is smaller than its cutting diameter. This allows it to fit into chucks that might not accommodate a full 18mm shank. Always ensure your drill chuck can securely grip the reduced shank to prevent slippage. It is compatible with standard drill chucks and drill press chucks.
Care: After use, clean the drill bit thoroughly to remove any metal shavings, wood dust, or plastic residue. A wire brush can be effective for stubborn debris. For optimal longevity, apply a light coat of oil to prevent rust, especially if stored for extended periods. Store the drill bit in a dry environment, ideally in a bit organizer or its original packaging.
