And now $257.40. I've been happier with mine since replacing the chuck with the Rohm Supra 871050.

I bought the drill thinking that I'd probably end up replacing the chuck. I'd done that on a friend's drill. The replacement chuck was less than $100 a couple of years ago. The main reason was because I couldn't get it to drill a row of holes in a straight enough line (with the timber up against the fence) using good quality drill bits.

The chuck that Bosch supplies is intended for a hammer drill not a bench drill.

I love the description for it:

About this item

• For quick stretching and remove the drilling tool; no keys needed.
• Higher elasticity, solid retaining ring, short design, less weight.
• Automatically nachspannen when drilling proportionally to the pull-out elasticity. So the maintenance of spann power even hard to use.

just a small one, may not look pretty, kind of heath robinson but it works, was cheap to make

was cleaning up shock bluddy horror and found these 2 parts from a long deceased angle grinder, only pho par was drill hole in the centre for a bolt to go through. err no gap behind before the Bosch handle is up against the shaft.

The bar that removes spacer on angle grinder had 2 pins ground off.

So I took the plunge and replaced the needle bearing at the backend of the chuck spindle with a mixed collection of 3 ball bearings (2off 8x12x2.5mm and 1off 8x12x3.5mm). Together with the chuck replacement, the run-out is much lower. I also cleaned up my replacement feed handle install around the hub. Much neater.

Ok, here is my effort to overcome the limitations imposed by the wheel. Borrowed most of the design from one of the 3D modelling sites with my redesign of the knob to be a bit more comfortable. It consists of two bolts, two bearings, three 3D printed parts and a bit of trial and error getting the holes spot on for a nice press fit for the bearings. So much better and easier.

great job, I tried one of those found on fleabay but it was about 5mm wider than the wheel itself, not matter how much padding I added in between. Finally ditched it but well done for your hard work.

I have no use for the old feed wheel and spacer/flange from my Bosch PBD 40. Anyone want them for free? Either pickup (Brighton VIC), or I can post them (if you pay for the shipping).

this Korean guy professes to be a mechanical designer rather than woodworker, however Id give almost anything to have his workshop.

He has been playing around with the illustrious Boche drill press and changed it a little.
I a, not game to say good or bad.... you decide

They’re back on AMAZON PRIME for $295. Think it runs out today or tomorrow?

Just bought this a couple of weeks ago, just to confirm this is a great little unit. really well made for the price.

I cant justify $2k on a Nova/Voyager as I dont use a drill press that often.
