Dormer A110 Long Series 3/16 In HSS Jobber Drill Pack of 10

Dormer A110 Imperial Long Series Drill Bits are designed for general purpose use with a long reach, enabling drilling deep holes in a variety of materials. Suitable for both hand and machine use, these bits deliver versatility for many drilling tasks. They are manufactured to standards including DIN 340RN, BS328, and ISO 494, ensuring compatibility with common tooling practices. The design emphasizes hot hardness with high speed steel construction, supporting reliable performance in demanding environments. The 118-degree tip provides a conventional point geometry that is easy to re-grind, while the added length offers extended reach for deeper holes. A steam oxide finish helps reduce built-up edge and improves lubricity during use. These features collectively make the A110 a practical choice for projects requiring a long-reach drill that can handle a range of materials, from softer to more challenging substrates, whether used in manual drilling or powered by a machine.
