Run true to +/- .002 No vibration at 6000 rpm's (max speed on my Haas)

Well worth the money

worked good holding drills

This is a decent drill chuck. I bought it to use as a dedicated chuck for a drill. The runout is acceptable. I use the drill before following it with a tap. The location is not extremely critical.I would have given this a five star, but the tool arrived with some very small dings on the taper. I lightly stoned them off, and I have had not issues.I would buy this again.

Very good quality for the price I have a small shop and these were perfect for me.

This product worked as advertised. I used it in my haas vf2. I use it to hold drill bits on parts where the tolerance is not a big deal. I have not checked parts off the machine to see what the accuracy is but all have been within what was needed. It seats in the spindle just fine and have had no issues with tool changes. I don’t give five stars because nothing is perfect.

My experience with these Collets are extremely positive they fit perfectly and our machine excellent.

I’ve seen this question asked a lot. So here’s the answer. I closed the jaws all the way and they fully close. It held a .010 gage pin just fine. Runout with a .200 pin was .001 TIR, and with a .5 pin it read .0055 TIR. The retention knob fit a haas VF2 with no problems. Rotating by hand to clamp down provides plenty of holding power for smaller drills, but I would use the spammer for anything over 5/16. Bearings feel decent, not rough. At this price, buy a couple.

Works fine in my haas mini mill. Good for the price.
