14mm – 25mm Drill bit Set | 13mm Reduced Shank | Blacksmith Drills | Rustung

Unleash Your Drill’s Full Potential
Discover Rustung’s 14 mm–25 mm Drill Bit Set, engineered with a smart 13 mm (½″) reduced shank to work harmoniously with today’s most common hand drills, pillar drills, or lathes. It bridges the gap—no need to invest in a heavy-duty chuck. Simply swap your regular bit for something far bigger, with ease.

Versatility Meets Performance
Inside this robust set are eight tough HSS blacksmith-style bits: 14, 16, 18, 19, 21, 22, 24 and 25 mm. Each bit shares the same 13 mm shank, making them suitable for tasks that demand larger holes, all while using your existing 13 mm drill chuck. From metalwork to timber, they rise to the challenge.

Built for Tradesmen—And the Tradesmen at Heart
These aren’t dainty bits. Based on the classic blacksmith drill design, they’re built for steel, cast steel, cast iron, aluminium, and even tough hardwoods. Picture drilling into a stubborn steel plate—no problem. These bits handle the heat and grind.

Outstanding Material & Durability
Crafted from High‑Speed Steel (HSS), these bits maintain hardness even at high temperatures. That means fewer dull edges, fewer replacements, and smoother, faster drilling. Each bit follows DIN 338-A drill standards and features the dependable 118° point angle for reliable centring without fancy tip geometry.

Precision Meets Simplicity
Don’t let size fool you. These bits deliver accurate results, thanks to tight manufacturing tolerances. Expect clean round holes, reliable depths, and a straight bore. Drill fabricators love them—and DIY enthusiasts will too.

Workplace Efficiency, Simplified
Switching bits is a breeze. No more fussing over mismatched shanks or oversized bits. Every bit in the set locks securely in a standard 13 mm chuck. This is time and stress saved—vital when you’re on-site or under a tight deadline.
