Drill Bit Set MILWAUKEE 25 pcs HSS-G Thunderweb 1–13 mm for metal

The MILWAUKEE 25 pcs HSS-G Thunderweb drill bit set 1–13 mm for metal is a selection of high-speed steel ground twist drills intended for drilling holes in a variety of metal materials. The set covers a continuous range of diameters from 1 mm up to 13 mm, making it suitable for precise small-diameter work as well as routine medium-size holes. Bits are designed for both hand-held and machine drilling applications in workshops, maintenance environments and fabrication tasks.

Advantages

Ground HSS construction delivers improved concentricity and cleaner chip evacuation compared with unground types, offering consistent hole quality across the included sizes. The Thunderweb geometry is engineered for reliable centring and faster penetration in metal, while the hardened, polished flutes help remove chips efficiently. The 25-piece assortment provides a wide coverage of common diameters, reducing the need to source individual bits for typical metalworking jobs.

Suitable for

• Drilling holes in steel, stainless steel and other ferrous metals
• General maintenance and workshop repair tasks
• Metal fabrication and assembly work
• Machine-shop operations and use with bench drills
• Handheld drilling where a range of small to medium sizes is required

How to use

Select the appropriate diameter for the required hole and secure the workpiece to prevent movement. Use a suitable drill chuck and ensure the bit is firmly clamped. For metal drilling, apply cutting fluid or lubricant to reduce heat and extend bit life. Start at a low speed to establish a centre, then increase speed within the drill’s recommended range for the selected diameter. Use steady, moderate feed pressure and clear chips regularly to maintain cutting efficiency.

Usage recommendations

For best results and longer tool life, use appropriate cutting fluid, moderate speeds and controlled feed when drilling metals. Inspect bits for wear or damage before use and replace dull drills to maintain hole quality. Store the set in its original case to keep sizes organised and protect ground flutes from damage.
