Dormer Pramet A777 1.20 mm HSS-E STRAIGHT SHANK JOBBER DRILL DIN 338

Introducing the Dormer Pramet A777 1.20 mm HSS-E Straight Shank Jobber Drill (DIN 338). This precision drill bit is built for metalworking where small, accurate holes matter. With a 1.20 mm diameter, it’s ideal for pilot holes, centering, and high-precision drilling across a range of metals.

Designed for a wide audience—from engineers and machinists to tradespeople and dedicated hobbyists—this drill delivers reliable performance in demanding applications. The straight shank fits standard chucks, and the 135° split point helps self-center the start, reducing wandering and the effort required to begin a hole.

• 135° split point for self-centering and easier starts: Centers the drill as it begins cutting, minimizes wandering, and reduces the push force needed to start a hole, speeding up setup and improving first-pass accuracy.
• Bronze oxide finish reduces sticking: The bronze oxide coating helps prevent built-up material at the cutting edge, promoting cleaner holes and longer edge life with smoother cutting action.
• Premium HSCO material with heavy-duty design for versatility: HSS-Cobalt (HSCO) construction handles drilling across steel, aluminium, and stainless steel, while a robust body is ready for tough materials and challenging applications.

Together, these features translate to consistent hole quality, reduced tool wear, and faster, more predictable drilling workflows. The DIN 338 standard ensures compatibility with common drilling equipment, and the straight shank provides secure grip and alignment for reliable performance project after project.
