Description
The Dormer Pramet A412 M4 HSS straight shank drill is designed for creating chamfered clearance holes for standard metric threads. It features an 118-degree pilot with a 90-degree chamfer, delivering clean, accurate clearance holes that simplify thread assembly and help ensure reliable performance.
Built from premium High-Speed Steel and finished with a steam oxide coating, this drill resists sticking and maintains a sharp cutting edge through multiple materials. Its specific pilot diameter and length are engineered to achieve the correct clearance drilling diameter and depth for standard threads. Versatile enough for CNC and conventional machines, it handles a wide range of materials including steel, aluminum, and stainless steel.
- Chamfered clearance holes: 118° pilot with a 90° chamfer creates precise clearance holes for standard metric threads, promoting easy assembly and better thread engagement.
- Specific pilot geometry for accuracy: Carefully defined pilot diameter and length ensure the correct clearance drilling diameter and depth every time, reducing guesswork and rework.
- Premium HSS with steam oxide finish: Delivers reliable performance across multiple materials (steel, aluminium, stainless) and smooth cutting on both CNC and conventional machines.
This drill supports efficient, repeatable results in everyday metalworking tasks. Its straightforward, straight shank design simplifies setup and aims to deliver consistent hole quality, helping you complete threaded projects with confidence and minimal downtime.
