Description
The Dormer Pramet A520 7.20 mm HSS TiN ADX Straight Shank Stub Drill is a reliable, general‑purpose drill bit designed for precision hole making in steel, aluminium, and stainless steel. With a 7.20 mm diameter, a straight shank (DIN 1897), and a Titanium Nitride coating, it starts cleanly, lasts longer, and performs consistently across a range of materials and applications.
- 130° Thinned Point for Self-Centering and Reduced Push Force: The sharpened angle and thinning improve starting accuracy and minimize the effort needed to begin a hole, helping you achieve true first passes with less drift.
- Titanium Nitride Coating for Longer Tool Life: TiN coating reduces wear and heat buildup, extending service life and maintaining sharpness for more holes between changes in the tool.
- Convex Cutting Edges for Efficient Chip Breakage and Higher Feeds: Designed to break and evacuate chips effectively, enabling higher cutting speeds and feeds while delivering smoother hole quality.
This high‑performance drill achieves precise, high‑quality holes with h9 tolerance, even at higher speeds, and is built to handle demanding production tasks as well as routine maintenance. The combination of premium HSS material, TiN coating, and a robust DIN 1897 straight shank provides dependable performance and easy interchange with standard equipment, giving you confidence to tackle a variety of projects with one versatile tool.
