About this item
- Premium HSS Construction & Precision Engineering: Made from High-Speed Steel (HSS 4341) for durability and heat resistance. Precision-ground with milled flutes and a 118-degree split-point tip for faster penetration, accurate positioning, and clean holes in tough materials like stainless steel and titanium alloys.
- Heavy-Duty Straight Shank Design: Features a full 1/2-inch (approx. 12.7mm) uniform straight shank on every bit. This robust design ensures maximum grip and stability in drill chucks, eliminating the need for adapters and reducing wobble or slippage during high-torque, large-diameter drilling operations.
- Built for Longevity & Reliability: Solid construction with a black oxide and silver finish enhances wear resistance and heat dissipation. The straight shank maintains its precision over time, supporting consistent performance and extended tool life under heavy-duty use.
- Complete Set in Portable Case: Includes 10 essential large-diameter sizes: 13, 14, 15, 16, 18, 19, 20, 22, 23, and 25mm. Comes with a durable metal storage case for easy organization, protection, and portability.
- Versatile All-Material Performance: Engineered to drill efficiently through a wide range of materials including iron, steel, stainless steel, aluminum, wood, and plastics. A truly universal set ideal for professional workshops, construction sites, and demanding DIY projects.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
