Dormer Pramet A110 3.40 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

The Dormer Pramet A110 3.40 mm HSS ST Straight Shank Long Series Drill (DIN 340) is engineered for dependable, precise drilling in a compact size. Designed for both handheld and machine use, this drill bit delivers consistent holes with minimal wandering, even when you’re working in tight spaces or deep cavities.

Precision tip you can rely on

Featuring an 118-degree conventional point, this A110 drill creates a strong, self-centering entry that stays true through the cut. The geometry is optimized for robust performance and easy re-grinding, so you can refresh the edge and maintain sharpness without swapping tools prematurely.

Steam oxide finish for cleaner cutting

The steam oxide coating reduces friction and inhibits material from sticking to the cutting edge. This means smoother chip evacuation and less built-up edge, helping you achieve cleaner holes and longer tool life in a variety of metals.

Long length, deeper reach

Part of the long series, this drill bit excels at drilling deeper holes and reaching recessed workpieces. The longer flute length maintains strength and stability, while the straight shank keeps alignment secure in both manual chucks and power drilling setups.

Premium HSS for versatile materials

Constructed from high-speed steel, the A110 handles a broad range of materials—from standard steel to aluminum and stainless steel. Its durable composition ensures reliable performance across common fabrication and maintenance tasks, with DIN 340 compatibility for interchangeable use in compatible holders.

Versatility for handheld and machine applications

Whether you’re in a workshop, on a production line, or conducting on-site repairs, this drill bit’s straight shank and long series design provide the flexibility you need. Fit for portable drills, drill presses, and automated equipment, it ensures accurate holes with minimal runout and consistent results.
