The Dormer A110 Metric Long Series Drill Bits are designed for general purpose long reach drilling, suitable for creating deep holes in a wide range of materials with both hand and machine use. Manufactured from high-speed steel (HSS) with a standard 118° right-hand point, these drills are designed for efficient cutting and re-sharpening. The line is produced to DIN 340RN, BS 328, and ISO 494 standards. An increased overall length provides deeper holes or greater reach, and a steam oxide finish helps reduce built-up edge and improve lubricity.
