Dormer High Speed Cobalt Drill Bit, 9mm Size, 84mm Overall Length, 40mm Drilling Length, Cylindrical Shank A9209.0

Dormer A9209.0 High Speed Cobalt Drill Bit is a premium quality tool engineered for industrial and mechanical use. With a size of 9mm and an overall length of 84mm, it offers robust performance and longevity when drilling through a range of materials.

The drill bit is crafted from high speed cobalt material which provides exceptional heat resistance and durability for industrial drilling environments. Featuring 3 helical flutes, it allows efficient chip evacuation to maintain optimal drilling speeds without clogging.

The cylindrical shank ensures a precise fit into drill chucks, enhancing operational safety and accuracy. Its bright, uncoated finish reduces friction and enhances cutting efficiency. The 130° special drill point angle improves centring capability and lowers the thrust required, making it suitable for deep hole machining up to three times the diameter.

The parabolic flute design contributes to rapid chip removal and greater drilling depths without the need for pecking. A thicker web increases structural strength to minimize the risk of drill breakage during demanding applications. This drill bit meets DIN SI standards, guaranteeing high manufacturing quality and reliability in professional settings.
