Dormer Pramet A110 9.30 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

Meet the Dormer Pramet A110 9.30 mm HSS Long Series Drill DIN 340 — a precision, straight-shank drill designed for deep-hole work in a range of metals. The 118° conventional point delivers a clean start and steady cutting action, while the steam oxide/tempered finish helps prevent workpiece material from sticking to the cutting edge, extending tool life and reducing downtime.

• Long length series for increased reach, enabling deeper holes and applications where standard drills can’t reach.
• Straight shank designed for secure guidance in drill chucks and machine spindles, minimizing run-out.
• Premium HSS material suitable for drilling a broad range of metals, including steel, aluminium, and stainless steel.
• DIN 340 compatibility ensures consistent geometry and interchangeability with standard holemaking setups.
• 6×D drilling without pecking optimized performance for steel, delivering efficient chip evacuation and steadier feeds in longer hole operations.

In practical terms, this drill is ideal for workshops and fabrication environments where you need reliable deep-hole performance without swapping tooling. Its combination of long reach, robust HSS construction, and a finish that reduces material buildup means fewer interruptions for re‑driving or re-sharpening, and more consistent hole quality across applications.

Typical dimensions for this long-series family place the A110 in the 170–175 mm overall length range with a flute length around 115 mm, aligning with DIN 340 standards and ensuring predictable hole geometry in demanding jobs. This makes it a dependable choice for through-holes, blind holes, and applications where access is limited.
