Technical Data

• Size & Shank: Sizes range from 9/16″ to 1″ in 1/16″ increments. All have a 1/2″ parallel tri – flat reduced shank, with jobber – length flutes and overall lengths varying by size (e.g., longer for 1″ bits than 9/16″ ones).

• Packaging: Packed in a sturdy case, easy to store and carry, with clear size markings for quick identification.

Advantages

• Universal Compatibility: The reduced 1/2″ shank lets large – diameter bits fit conventional handheld power tools, avoiding slipping in the chuck without needing special drills.
• Durable & Clean Drilling: HSS ensures heat resistance and durability for drilling steel, aluminum, stainless steel, etc. The steam oxide finish prevents material sticking, resulting in clean, accurate holes.
• Wide Application: Covers 9/16″–1″ sizes, ideal for drilling large holes in metal, wood, and plastic, suitable for both handheld and machine – based tasks in workshops and professional projects.
• Easy Storage: The matching sturdy case protects bits from damage during transportation and storage, and the size – sorted design saves time in finding the right bit.
