28122 Chuck for Drill Bits up to 15/64-Inch for TBM 115

Works great with the drill.

I did a slight diamond honing and cleaning in an attempt to minimize runout. No runout was wanted for my precision need. This chuck did work well as you can see in this "test spin" into light metal.

A good extension for the Proxxon mini drill press. It allows you to use larger bits than the 1/8 inch standard for the individual chuck inserts that come with the drill press. But keep in mind there's limited space and long bits won't fit in the limited vertical space between chuck and base

This is a great addition to my drill press. It adds speed and convience to the use of my drill press.

Was using a chuck I salvaged from one of my broken mini battery drill, which worked great yet looked like oversized for the little proxon press and could not clamp tiny bits. Only wished it was made in USA or Germany other than that it's great.

Purchased for the TBM 115 - using the included rod unscrewed the collet nut and removed the collet then screwed this on tightened with the rod and the included chuck key handle - no issues or problems it just works perfectly - if you purchase or own a TBM I would recommend.

I dont know if it was me or the drill but it got to where I couldnt keep the bit tight enough with the original collet. The chuck works great, stays tight and easy. I realize I could change the collets out but an adjustable chuck is much more convenient.

I rated this a little better than the other Proxxon accessories. It's very useful for larger diameter bits and it functions properly. It's well constructed and precise enough. It also doesn't cost an arm and a leg, unlike other Proxxon accessories. If you already have the Proxxon, it's worth it to get this part.

Ik was toe aan een andere mandrino die vorige van mij was versleten en ook was mijn sleuteltje zoek. Nu kan ik terug werken zoals voorheen met mijn Proxxon toestel

Das Bohrfutter passt und funktioniert gut. Hab es allerdings noch nicht viel in Betrieb gehabt. Macht aber einen soliden Eindruck

Must have accessoire for a table drill..

Molto comodo e preciso
