Application & User
The Cobra Carbide 55960 is a 3xD high-performance drill bit designed for pneumatic drilling operations. It suits machinists and maintenance teams who need a dedicated non-coolant tool for producing accurate holes in metal workpieces. The 9.70 mm cutting diameter and 10 mm shank fit standard tool holders used in workshop environments.
Decisive Specification
This drill operates without through-coolant, so chip evacuation relies on the flute geometry and the 3xD length ratio. The 9.70 mm metric size determines the exact hole diameter produced, making it the critical figure for matching the tool to the drawing specification. Selecting a different diameter would create an out-of-tolerance bore.
Sustained Operation
During extended drilling cycles the non-coolant design means heat builds in the cutting zone rather than being flushed away. The carbide substrate resists wear at elevated temperatures, allowing the bit to maintain size consistency over repeated holes. Operators should monitor chip packing in deep cuts because the 3xD depth can trap swarf without coolant assistance.

Questions about this item
What does the 9.70 mm drill diameter mean when I am machining a hole?
The 9.70 mm diameter produces a finished hole of that size in a single pass with this 3xD drill.
How does the 10 mm shank diameter affect tool holding?
A 10 mm shank fits a 10 mm drill chuck or matching collet for secure clamping.
What physical space does the 3xD length need in my machine setup?
The 3xD design requires clearance for roughly three times the 9.70 mm diameter in flute length plus shank engagement.
