Imbalance and vibration problems caused by burrs!

50% of spring collets had burrs during machining which caused imbalance/vibration and prevented the collet from being properly clamped on the tool. I had to use a Razor blade deburr solve the problem.

Pros
  • Accuracy: 0.02mm (0.0008").
Cons
  • Damaged

Poor finish Suitable for cutter parts and accessories

Such a hodgepodge lottery house collet. Some are very good, some are terrible. The 1/4 I got with my set was terrible. Should never have entered the market. About 0.7 mm from the center. Do yourself a favor and buy Technics (sp?) "super accurate" collets in the sizes you need. A collet will cost as much as this whole set, but at least they'll actually do the job.

Pros
  • Clamp range: 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 1/4", 1/8".
Cons
  • A few little things

Fantastic collet set

Excellent collet set! I ordered them to upgrade my CNC machine which used a simple bushing with set screws to attach the tool to the motor spindle. This assortment allows me to securely mount my end mill or engraver in my machine without having to worry about the set screws not holding it securely. Great product, great price and perfect upgrade for my CNC machine.

Pros
  • Hardened and precision ground.
Cons
  • Difficult to say

Prefect collet set for my CNC

I have a set of 15 collets, metric and two imperial 1/8" and 1/4" that will fit almost any bit you can find for this collet. I didn't see any escape. The engraved size mark makes it easy to choose the right bit as sometimes there are a few sizes that fit, but once you tighten you realize you can go down a size. Comes with a small plastic case for each collet. Ideal!

Pros
  • Material: Made of special spring steel.
Cons
  • Miscellaneous Miscellaneous
