Description
The Dormer Pramet A108 3.70 mm HSS straight shank drill is a reliable all-around tool designed for metalworking. With a 3.70 mm diameter and a DIN 338 straight shank, it fits a wide range of hand-held and machine setups and is suitable for drilling steel, aluminium, stainless steel, and other common metals.
Its 135‑degree split point self-centers on entry, reducing walk-off and the push force needed to start a hole, so you get crisper starts and more accurate results. The steam oxide finish helps prevent workpiece material from sticking to the cutting edge, delivering smoother cuts and longer tool life. A patented Silver Ring marks genuine Dormer quality and clearly indicates the drill diameter for quick identification.
- Self-centering 135° split point: Starts accurately with less push force, reducing walking and improving hole quality in tough metals.
- Steam oxide finish: Minimizes material buildup on the edge, promoting smoother cutting and longer drill life across steels and aluminum.
- Genuine Dormer Silver Ring with DIN 338 diameter: Signals authentic Dormer tooling and makes diameter easy to read, while ensuring compatibility with standard chucks and fixtures.
Together, these features translate to faster, more reliable drilling with consistent results across a variety of materials. The durable HSS core and standard straight shank offer versatile use in both handheld and machine applications, helping you complete jobs with confidence and less downtime.
