Collet recommendation?

[Adam Stein]

I use a ShopBot in a maker space, and the shared collets are fairly chewed up. I want to invest in some of my own, but I'm having trouble differentiating between them. Is there anything to look for in a "good" collet? For starters, I want an ER25 for 1/4" shanks.

Here are some that I found:


TECHNIKS 1/4" SUPER PRECISION ER25 COLLET .0002 ACCURACY CNC CHUCK MILL (https://www.ebay.com/itm/TECHNIKS-1-4-SUPER-PRECISION-ER25-COLLET-0002-ACCURACY-CNC-CHUCK-MILL-/130701349603?hash=item1e6e6852e3)
Amana CNC High Precision Spring Collets for ER25 Tool Holder (https://www.toolstoday.com/cnc-high-precision-spring-collets-for-er25-tool-holder.html?variantids=11644,0&keywords=CO-286)
HHIP 3900-5215 ER-25 Spring Collet, 1/4" (https://www.amazon.com/HHIP-3900-5215-ER-25-Spring-Collet/dp/B01ABWS9IG/)
Dorian Tool ER25 Alloy Steel Ultra Precision Collet, 0.236" - 0.276" Hole Size (https://www.amazon.com/Dorian-Tool-Alloy-Precision-Collet/dp/B00CB14HXW/)


There is also one for sale on the ShopBot website, but it's about twice as expensive as the others. Suggestions welcome!

You want the Techniks - same as OEM. The one you listed should be fine. That's a good price if genuine Techniks.

OK, thanks. Any details on why? Is Techniks just regarded as the best supplier?

[Brady Watson]

Don't know about 'best', but Techniks is of good known quantity and high quality...

Techniks is perfectly good stuff, but for what it's worth, myself and others here have discovered the Shars brand of collets/accessories. Very good quality and pricing. Many reputable companies are migrating to ebay for store fronts, so don't let the ebay thing dissuade you. Check out their store - here is an ER-25 example:

https://www.ebay.com/itm/1Pc-ER25-Collet-Ultra-Precision-5-Micron-1-8-3-16-1-4-5-16-3-8-7-16-1-2-9-16-5-8-/351913325517?var=&hash=item90a9c5d51e

Provided the specs are accurate, the "ultra precision" versions are very impressive.
Every collet, nut and wrench I've purchased from them was of exemplary quality - great bang for your buck.

You do right to get yourself a good collet, it will help to protect your cutters. I would get a collet nut also.

What is the state of their spanner?

In good faith

[Adam Stein]

It's an active maker space, so all of the publicly available equipment is pretty chewed up. I hadn't really thought about getting my own spanner, but it's only $10 for one, and Shars is running a sale this week. Should I get one?

[jTr]

I would recommend it. You'll find the Shars is 50% thicker material than what originally came with the machine.

[Adam Stein]

Great, thanks for the tip. With the Black Friday sale they are running, the wrench is only $8.

Maritool. Top quality stuff, good prices.
