Dormer Pramet A110 1.30 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

Designed for precision micro-drilling, the Dormer Pramet A110 1.30 mm HSS long series drill is a reliable choice when you need accurate holes in tight spaces. This DIN 340-certified drill combines a strong, self-centering start with long-reach capability, making it ideal for deep holes and hard-to-access workpieces.

• 118° conventional point delivers a strong, self-centering start and is easy to regrind, helping you maintain sharpness and reduce tool costs over time.
• Steam oxide (steam tempered) finish minimizes built-up edge and prevents workpiece material from sticking to the cutting edge, promoting smoother feeds and longer edge life.
• Long length series with straight shank provides extended reach for deeper holes while staying compatible with standard chucks and machine spindles, making it versatile for both handheld and machine drilling.
• Premium HSS material engineered for durability across a range of materials, from steel to aluminum and stainless steel, so you can tackle mixed-material work without swapping tools.
• DIN 340 conformity ensures consistent geometry and interchangeability within the Dormer Pramet long-series family, so you know you’re getting a proven, standards-compliant drill.
• Deep-hole capability designed for drilling deeper holes with confidence; the long flute and overall length support 6×D drilling without pecking in steel, offering practical reach for demanding tasks. The typical overall length is around 65 mm with a 41 mm flute length for micro-diameters like 1.30 mm.

Who should reach for the A110 long-series drill? technicians and machinists performing precision work in delicate or constrained environments, electronics enclosure fabrication, thin-winish metalwork, and light-to-medium steel or aluminum components. Its combination of a true 1.30 mm cutting diameter, robust HSS substrate, and regrindable 118° point makes it a dependable choice when you need repeatable holes with clean edges, without changing tools mid-project.

Practical tips for best results:

• Use a suitable slow-to-moderate spindle speed with adequate lubrication to minimize heat buildup on small-diameter drills.
• Keep the point sharp; the 118° tip is designed for straightforward regrinding to maintain accuracy and prolong life.
• Choose the long-series drill when you require additional reach into pockets, blind holes, or recessed workpieces.
• Inspect the workpiece material compatibility (steel, aluminum, stainless) to select the appropriate feeds and speeds for clean hole finish.
