Dormer A101 HSS Left Hand Spiral Jobber Drill Bit, 2.5mm

The Dormer A101 Metric Traditional Flute Ground Jobber Drill Bit is designed for precision and durability in general machining applications. Crafted from high-speed steel (HSS), this drill bit features a left-hand spiral and a blue finish (bright for diameters below 3mm), ensuring reliable performance and resistance to wear. Manufactured to stringent DIN 338 LN, BS328, and ISO 235 standards, it guarantees consistent quality and accuracy.

With a standard helix flute geometry and a 118° point angle, this drill bit efficiently removes chips and prevents clogging. Its left-hand spiral design makes it particularly useful for specialised applications requiring reverse drilling. The robust construction and precision-ground flutes ensure optimal cutting performance in various materials.
