Minimum Requirements

The success of any Titespot® coolant driven tool depends on the combination of correct product selection for application and machine tool coolant pump specification.

There are three main factors that we are looking to achieve:

Speed (RPM)

The rpm developed by the angle head is a function of coolant flow rate (litres per minute). The Titespot® angle head will rotate at approximately 238 rpm per litre of flow.

Torque (Nm)

The torque developed by the angle head is a function of coolant pressure (Bar/PSI). Under test conditions the positive displacement ball piston motor develops .03 Nm of torque per bar of coolant pressure.

Machining power (Kw) & metal removal rate (cm3)

This is a direct correlation of flow rate and pressure. As a guide, in steel the metal removal rate is 22cm3 of material per minute per kilowatt of power generated.

Machine tool coolant filtration also plays a vital role. Although Titespot® angle heads are not too sensitive to contaminated coolant, particulates in the solution can cause premature wear to bearings and gears and ultimately 'locking up' of the motor if large or, a continuous build-up of particles are allowed to enter the head.


We recommend a 50 micron pre-filter followed by a 10 micron filter, for best results this should be on the pressure side of the system.

Good filtration is also recommended on your compressor driving the air hose and air blast system. Most machine tools will spin the tool at every tool change and machinists will also tend to use air hoses to clear the tool when storing away.

The figures quoted opposite apply to standard product. For 'heavy duty' or more demanding cutting operations that may benefit from higher torque at lower speeds, gear reducers and special motors can be offered.
