Description
The Dormer Pramet A170 is a 9/16 inch diameter HSS jobber drill with a straight 1/2 inch shank, built for dependable metal drilling in handheld tools and machine setups. It’s a trustworthy choice for professionals, engineers, tradespeople, hobbyists, and DIYers who need clean, consistent holes through steel, aluminum, and stainless steel.
- 118° Conventional Point: Provides a strong, self‑centering starting edge that helps holes begin true and stay on track; easy to re‑grind to maintain sharpness over time.
- Steam Oxide Finish: Reduces material sticking to the cutting edge, improving chip flow and delivering smoother cuts with longer edge life.
- 1/2 in Parallel Shank: Fits standard chucks and holders, enabling secure use of larger‑diameter drills in both handheld tools and machine applications.
This drill combines versatile HSS performance with practical design details to support quick, accurate holemaking across common metals. Whether you’re drilling steel, aluminum, or stainless steel, the A170 delivers reliable results with a stable grip, easy maintenance, and long service life.
