Dormer Pramet A110 7.40 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

Dormer Pramet A110 7.40 mm HSS Straight Shank Long Series Drill, DIN 340 is built for serious metalworking tasks where depth and precision matter. This long-series drill combines a robust 118° conventional point, a steam-oxide finish, and premium high-speed steel to deliver dependable performance across a wide range of materials.

• 118-degree conventional point: A strong, self-centering tip that starts cleanly and resists wandering. The geometry is straightforward to re-grind, helping you extend tool life between sharpening sessions.
• Steam-oxide finish: Reduces built-up edge and prevents workpiece material from sticking to the cutting edge. This enhances chip flow and minimizes workpiece pull-in, especially on ferrous materials.
• Long length series: Designed for deeper holes and applications where increased reach is essential. The extended flute length improves chip evacuation and clearance in thick sections or blocked workpieces.
• Premium HSS material: Versatile enough to drill a variety of metals, including steel, aluminum, and stainless steel. The alloy blend balances hardness, wear resistance, and toughness for durable performance in everyday shop environments.
• DIN 340 standard: Engineered to meet common industrial interchangeability, ensuring compatibility with standard holders, chucks, and machine setups while maintaining consistent drilling results.
• Versatility in one tool: Suitable for use in both handheld drills and machine-driven setups, making it a reliable choice for workshops that require adaptability without swapping tools.

Ideal for engineers, fabricators, and hobbyists who need reliable deep-hole capability in metals. The A110 7.40 mm drill excels in penetrating through thicker workpieces, fixture drilling, and situations where access is limited but hole depth is critical. Its durable HSS core, combined with the Steam-oxide finish, delivers consistent performance across multiple materials, reducing downtime and sharpening cycles.

Practical tips for best results: - Start with a slow, stable feed to seat the tip and reduce deflection on harder materials. - Use light lubrication when drilling stainless steel to minimize heat buildup and edge wear. - When re-sharpening, preserve the original point geometry to maintain expected cutting behavior. - For deep drilling, ensure proper chip evacuation to avoid clogging and work hardening at the bottom of the hole.
