Dormer Pramet A110 10.50 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

Meet the Dormer Pramet A110 10.50 mm HSS straight shank long-series drill — a purpose-built tool for reliable, deep-hole drilling in a wide range of metals. Designed to DIN 340 standards, this drill combines robust performance with practical reach, making it a staple for professional workshops and serious hobbyists alike.

• 118° conventional point — a strong, easily re-grindable tip that starts cleanly and maintains cutting efficiency through the full drill cycle.
• Steam oxide finish — a steam-tempered surface that reduces friction and helps prevent workpiece material from sticking to the cutting edge, promoting steadier feeds and smoother holes.
• Long length series — extended reach for deeper holes and applications where standard drills can’t access the target area, without sacrificing straightness or rigidity.
• Premium HSS material — versatile, durable steel suitable for drilling a broad spectrum of materials, including steel, aluminium, and stainless steel, making it a reliable all‑rounder in mixed material environments.
• Straight shank & DIN 340 compliance — compatible with standard chucks and holders for both handheld and machine drilling, simplifying tool inventories and swapping between stations.
• Versatility in one tool — a single drill that handles a wide variety of common metalworking tasks, reducing the need for multiple drill types in many shops.

Use cases and practical tips: when you need to penetrate metal floors, panels, or structural components with precision, the A110’s long reach helps maintain control while evacuating chips. For best results, pair it with appropriate feeds and speeds for the material, secure the workpiece firmly, and rely on a clean center mark to ensure a true start. The drill’s steam oxide finish and high-speed steel core work together to deliver dependable performance across steel, stainless steel, aluminum, and other common alloys.

Why choose this drill over shorter, standard drills? The extended flute length and straight shank design maximize reach and stability for deep-hole work, reducing the need to switch tools mid‑job. The combination of DIN 340 conformity, a robust 118° point, and a steam-tempered surface creates a tool that not only starts easily but also resists wear and chip welding under demanding conditions.

Ideal for professional machinists, fabrication shops, and hands-on technicians who regularly drill deeper holes or work with a mix of metals. The A110 10.50 mm drill is a dependable addition to any drill kit, delivering consistent hole quality, fewer tool changes, and extended service life in everyday metalworking tasks.
