Alouette Tool is proud to represent CoolSpeed – a Ultra High Speed Machining Spindle achieving up 4 to 8x machining speeds of standard machines spindles with their patented technology.

CoolSpeed‘s three different spindle lines (Mini, Air, and Flex) are driven by coolant, air, or oil and can reach up to 80,000 RPM – drastically reducing machining times. The Spindle’s are available in 16mm, 20mm, 22mm, 25mm, and 3/4″ shank sizes and have adapters available to fit almost any machine position/gang – including Swiss machines.

CoolSpeed Saves Money!

• Economical price point gives great ROI
• Increased cutting tool life
• Reduced cut times
• Extends life of main spindle
• No maintenance required! (Fully rebuild spindle in seconds!)
• Maximize productivity and gain more business by upgrading your micro-machining capabilities

CoolSpeed Flex

Revolutionary patented spindle technology for rotation speed up to 80,000 rpm


Designed specifically for Swiss Machines, CoolSpeed Flex is a new type of high speed, turbine-driven spindle that features an adjustable number of jets. This innovative new design allows the Flex to operate on machines with coolant flow as low as 2 gal/min (8 l/min). 

With Flex, the cutting tool shank serves as the spindle shaft, pressed between two bearings and a turbine. The coolant pressure drives the spindle speed, and the RPM can be monitored using the Bluetooth Pressure Gage (included in the starter kit) or a standard G1/4″ Pressure Gage. Operators can set the number of jets for optimizing coolant usage, and monitor the RPM in real time from their smart phone via the Apple or Google CoolSpeed app.
