The Dormer Pramet A022 8.30 mm HSS TIN Straight Shank Stub Drill is a versatile metalworking bit designed for both hand-held and machine use. With an 8.30 mm diameter, it’s built to deliver consistent, precise holes across common metals, including steel, aluminium, and stainless steel. This DIN/ANSI-standard drill combines a robust HSS core with a Titanium Nitride coating to maximize life and performance in everyday workshop tasks.
Equipped with a 135° split point, it self-centers and starts holes cleanly when used by hand, reducing the push force required and helping to prevent wandering. The Titanium Nitride coating extends service life and enhances performance when drilling harder materials, while the premium HSS core supports accurate holes and a quality finish across a range of metals.
- 135° Split Point for self-centering: Starts holes precisely by hand and reduces pushing effort, helping prevent wandering and improving first-pass accuracy.
- Titanium Nitride coating for longer life: Reduces wear and maintains sharpness, delivering more productive drilling on harder materials.
- Premium HSS with DIN/ANSI straight shank: Provides reliable, versatile performance across hand-held and machine applications, compatible with common chucks and holders.
Together these features help you complete metalworking tasks with consistent quality, fewer tool changes, and smoother setups. The drill’s 8.30 mm diameter, TiN coating, and durable HSS core make it a dependable choice for daily drilling across steel, aluminium, and stainless steel in both manual and powered tools.
