TS-11 300W, 60,000 RPM Spindle ER8
300 W AC spindle, 25,000-60,000 rpm, ER8 collet, 48 mm dia x 137 mm, 1.5 kg, 75 V three-phase via VFD.
Overview
The TS-11 is a 300 W high-speed spindle built for engraving and fine detail work, where small tooling needs very high rpm rather than torque.
It runs at 25,000-60,000 rpm - well above the 10,000-24,000 rpm range of the general-purpose spindles in this catalogue - and holds tooling in an ER8 collet, which suits the small-diameter engraving bits and PCB drills this speed range is meant for.
The body is compact at 48 mm diameter and 137 mm long, and weighs 1.5 kg, light enough for a small gantry moving fast over engraving work.
Power is 300 W from a 75 V three-phase supply at 4.5 A, delivered through a variable frequency drive matched to the motor; the VFD's output frequency sets the running speed within the rated range.
For general milling and routing rather than fine engraving, the ER11-collet spindles in this range (TS-12 upward) run at lower speed with more torque.

Questions
Can I run this directly off a three-phase supply, or does it need a VFD?
It needs a VFD — power is delivered through a variable frequency drive matched to the motor, and the VFD's output frequency is what sets the running speed within the rated range.
I want to use this for general milling and routing, not just engraving — will it hold up?
Not really its job — this one's built for engraving and fine detail work, where small tooling needs very high rpm rather than torque. For general milling and routing, the ER11-collet spindles in this range (TS-12 upward) run at lower speed with more torque instead.
Why such a small collet — what tooling does this actually take?
An ER8 collet, sized for small-diameter engraving bits and PCB drills — a match for the 25,000-60,000 rpm range this spindle runs at.
Is it light enough to mount on a small gantry moving fast?
Yes — 1.5 kg, 48mm diameter and 137mm long, sized for exactly that kind of fast-moving small gantry work.
What does the VFD need to supply it?
300 W from a 75 V three-phase supply at 4.5 A.
