Einhell Bench Drill

I took possession of the Bench or Pillar Drill; Einhell TE-BD 750 E Expert 750W Bench Drill.
Installed the base, fitted the pillar to the base and two of us lifted the machine up onto the pillar.
Fixed it in place, as per the instructions, bearing in mind it weighs a hefty 45kg, so not easy to install on your own.
Finished installing the safety stuff and plugged it in.
No light and no revolution display.
Pressing the stop button caused the light to flash, so an intermittent connection I would think. The box it came in was a little worse for wear.
The actual machine was pristine, so no issues with that.

I removed the front cover to find loose and poorly crimped 4mm spade connectors. Replaced them and tested again. Still intermittent.
Having a closer look at the power supply board, no output from the two connectors, +3 and +5 volts DC.
Removed the board and the transformer had a broken secondary wire.

Removed the transformer, found and repaired the broken wire and replaced it into the control panel.
Powered it on and perfect.

It was that or put it back in the carton, repack it and have it replaced. I chose the easiest option, repair it as it was a minor issue.

A varied day today.

Congrats - I often do the same. If I can fix it reasonably, I'll go with it. Einhell - I think - rebrand stuff that's often sold under 'house brands' of various places. It's generally not the absolute best out there but decent and fairly reliable.

Nice job on fixing it up! :yesway:

Does it have a speed control? A lot of them don't and I actually drew up the plans for a VFD to retrofit into one. Unfortunately, I didn't get to pick the unit in question up due to a violent neighbor but that's another story.

It has a CVT gearbox with a belt and has a range of 25 - 3000RPM.
Very useful, with a speed control on the side and an RPM meter on the top of the stock.
Hand operated, keyless chuck.
Made in Germany.

Nice unit! I wish my old Rockwell had a variable speed control. I have to move the belt between different pulleys. On the plus side, it is a floor model with a lot of horse power and has a 1/2" chuck (keyed). It was my wife's grandfather's drill press. It was made in the U.S. when good industrial grade stuff was actually made here.

You would have to check the motor inside, but chances are it's frequency controlled, i.e. you need a VFD or Variable Frequency Drive. These *can* be retrofitted, but there are risks involved. The lower the frequency the more magnet saturation you get in the motor itself and so on. I wouldn't do that on a decent unit, but if you can pick up a old cheapy (like what I was about to get) it could be worth it. I was also going for a model sold under 10 brands/model numbers so parts are available. That's another thing about Einhell, by the way - they OFTEN can supply spares if something does go South.
 
Very pleased with the power. 1 hp, (745W), is adequate for drilling 3mm aluminium chassis, up to 13mm, I have Q max Hydraulic Tank Cutters for larger holes, valve bases etc.
It has a brushed motor, unlike the cheaper induction motors, so controlling the speed of the motor is easy if I need any more variation.
