Description
The Dormer Pramet A120 5/16 Inch HSS Stub Drill with a straight shank (DIN 1897) is built for reliable metal drilling. It’s a practical choice for professionals and DIYers alike, delivering clean, accurate holes with minimal wandering.
Designed to cut across multiple materials—steel, aluminium, and stainless steel—the 5/16" diameter is a versatile option for pilot holes, prepping threads, or general machining. The stub length and robust HSS core provide rigidity in handheld drills and machine tools, helping you work efficiently and with confidence.
- 135° split point for self-centering: The 135-degree geometry initiates a true entry, reduces wandering, and lowers push force to help you start holes quickly and accurately.
- Steam oxide finish for reduced sticking: A smooth, low-friction coating minimizes chips and prevents workpiece material from adhering to the cutting edge, boosting finish quality and reducing snags.
- Premium HSS material for versatility: High-speed steel provides durable performance across a wide range of metals, including steel, aluminium, and stainless steel, making it suitable for both handheld and machine drilling.
With this drill, you address common metalworking challenges—wandering starts, rough holes, and tool wear. The A120 stub drill delivers consistent start holes, smooth finishing cuts, and reliable performance across diverse materials, helping you complete projects with fewer passes and less rework.
