PiBurn Grip Rotary Attachment

Take your laser engraving to the next level with the BEST CHUCK ROTARY on the planet

Update (11/28/2023): The current lead time is 10 business days plus shipping

The PiBurn Grip is a patent-pending chuck-style rotary attachment for laser engraving machines. The revolutionary PiBurn Grip brings you incredible precision, repeatability, and the freedom to engrave almost anything you can imagine. It will take your laser engraving to the next level.


With this rotary you can do anything.



Why is this so exciting?
The Grip is a chuck-style rotary, but it’s more than that. This PiBurn Grip chuck system was designed and built by LensDigital from scratch. It is the only chuck on a rotary designed specifically for laser engraving. Other systems borrowed from the lathe and drilling applications – they are heavy and bulky and can’t hold the delicate glass without breaking it. In short, they are not ideal for laser engraving. The frustration is something we couldn’t let stand!
We have spent years conceptualizing and bringing this tool to makers, and we are so excited at the new opportunities it will open for you and the products you can offer to your customers.

The benefits of a chuck are plenty, but here are a few:


  • Never worry about walking or horizontal shift
  • The cup will not slip, so you can engrave in both directions, not just line by line. This allows for scoring – when the laser moves continuously, like when cutting.
  • You can now make multiple passes and engrave in layers
  • Frame at high speeds – no risk of your tumbler slipping off the rotary
  • Engrave rings, pens, drumsticks, and other small items
  • Engrave mugs with heavy handles without the worry of slipping
  • Engrave non-cylindrical items with ease
  • The Grip uses a Direct drive system, no belts, no gears – fewer parts to wear and break
  • There is no need to change steps – only the object diameter


Benefits of the PiBurn Grip above and beyond any chuck are:


  • No tools are required to tighten the Grip! Simple and quick swapping, tighten and loosen with your hands. If you need a little extra, we include a handy little lever to tighten, but it’s super quick and easy.
  • Adjustable angle like the original PiBurn for tapered objects
  • Includes rubber-padded “fingers” for the extra delicate glass items
  • Extra long jaws are included for items like dog bowls, rolling pins, and niche applications.
  • Have a PiBurn? The PiBurn Grip can be purchased as an add-on to the PiBurn 4, and then it becomes two rotaries in one, providing you with backup for your operations – there are two separate motors (chuck has a dedicated motor)
  • The jaws are interchangeable, so you can configure the Grip to.. well.. grip anything you can imagine!


What can it do?

“What can’t it do” is the better question!


Already have a PiBurn and looking to add the Grip to your V3 or V4 PiBurn?

Buy the Grip Addon Kit!


Looking to build the PiBurn Omni?

The Omni configuration mounts the Grip on top of the Roller Wheels of your PiBurn V3 or V4. To do this with the V3 you must have a metal clamp, it will not mount on top if you have a plastic clamp. You will still be able to use it as a standalone Chuck rotary.

To build the Omni:

Buy the PiBurn 4.0


Buy the Grip Addon Kit!

The below video shows a technique called “Scoring.”

It allows the laser to move in a continuous motion, instead of line by line. This is only possible on the PiBurn Grip as any roller rotary will not have enough friction to allow for the back-and-forth motion needed for this technique.


Engrave small objects easily.

Oddly shaped objects that can’t sit on wheels are no match for the Grip!

    I just have to take a sec to give a HUGE shoutout to Len Karchevsky and Stan Altshuller for creating such a magical device that I’m CONVINCED has changed my life!

    When I upgraded from an xtool to a Thunder I needed to upgrade my rotary as well. My laser bestie recommended a Piburn Grip, and I maaaaaybe hesitated for a sec when I saw the price. But I’m just here to say it is worth absolutely EVERY PENNY!!! I ordered one for my Bolt and was immediately in awe the second it arrived… after I was done snacking on those gummies. It was night and day and I knew I’d never go back to anything else. Fast forward a bit and I needed to change from the Bolt to the Nova 24, and I was worried the grip wouldn’t be compatible so I emailed to ask and found out (in maybe an hour tops) that it was! Which… *whew* because I literally would have ordered a second one if not. ‍

    I went on and ordered the longer rail needed for the bigger bed, and was shocked that’s all I needed. No crazy gadgets or add ons or things that seemed pointless, just the rail. When it came in the mail (in record time, I might add) I was a little worried it was going to be difficult to swap the parts out. But guys… it was like high tech legos, and I mean that in THE best possible way! The pieces were SO easily interchangeable I had everything swapped out in minutes!

    I recommend this thing to everyone with ears, or eyes if we’re in a group, because no one will ever convince me there’s a better rotary! I am team “PiBurn for life” and already have plans to order my next one when my new Aeon redline comes in!

    TL;DR: PiBurn is life, your cups will be amazing, and the gummies are the best in the land.

    I sort of freaked out when I saw the price of this part. Once I got it, started to use it and found that the PiGrip is not only made with all the precision of best-in-class parts, but the design itself has been thoughtfully and thoroughly had the proper attention put into it. I do not regret buying this and I recommend it to every Galvo and CO2 laser owner. I have used on both my Galvos as well as my CO2 Gantry laser and all have been flawless. There really is no equal in quality, build and most importantly, BEST is customer service. LensDigital goes above and beyond to ensure that their customers are treated like 1st class passengers all the way. I proudly place my swag on my lasers and tell others about these awesome tools. I am Team Pi all the way!!

    You won’t regret this purchase! The best tool I have added to my shop. Works flawlessly! The support is also top notch. Everyone is so helpful and knowledgeable.

  4. Jan Gorshack (verified owner)

    Attempted to use the hotdog style roller that came with our laser. Not much luck, so after reading up on rotaries and watching a bunch of videos we decided to purchase the piburn grip. I have no idea why we waited. We have done everything from tumblers, slim beverage holders, wine bottles, wine glasses to 100 shot glasses for our sons wedding. Don’t let the cost hold you back from purchasing. Yes it’s a good chunk of change, especially if you just bought a laser like we did. But when you hold it you realize they went first class with every part We paid for ours in under 2 months.

  5. Doug Bollenbach

    The grip as it is OFFICIALLY called is a beast! It ties directly into the original roller setup without having to do away with rollers! This whole rotary amazes me as to how versatile it is! Is also fully compatible with my fiber! I wouldn’t consider any other rotary! A must have for any setup/machine!

  6. The Laser Chick

    Wonderful and precise rotary option. Versatile and effective. I will definitely be purchasing another for my new laser also in the future.

  7. Beth Parsons

    Even though I already have 3 different rotaries for my galvo lasers, I ordered The Grip hoping it would help me achieve a greater level of precision and eliminate a lot of the frustration surrounding the standard-issue metal chucks. And it certainly did not disappoint! Fast and easy to swap out items between runs, simple to adjust, and gentle yet secure grip on even the thinnest glassware. HOMERUN!!!

  8. Heather Lynn

    The Grip is awesome! I have had a V4 for a few months and I always had issues with tumblers and mugs with heavy handles… well, those are NO problem for the Grip!

    It’s also user-friendly and comes with a bunch of options for ways for it to hold onto SO many different types of items!


  9. Ida

    The grip allows me to engrave all the odd shaped items I have purchased in the past wanting to engrave but couldn’t. I am so excited to own and use this new revolutionary rotary!! It also makes engraving all the things that are harder to set up on the piBurn like steamed glassware and so much more! I also loooove that using my grip allows me to maximize the Z travel space on my Mira 9. I can now engrave bigger things like dog bowls where before they were too tall between the rollers and item to be engraved.
    I’ve even engraved tiny things like silicone rings on my new grip!
    This is a must have for any laser engraver once they master the Piburn!

  10. Robert Kofoed

    The Grip is a fantastic tool for engraving a wide range of products. I’ve been using it for a bit now and love how easy it is to use and it’s opened up possibilities I wouldn’t have with a roller rotary. I’ve got mine set up Omni style. Which means I have both the roller and the grip on top. One thing when using the grip you don’t need to change steps per rotation when engraving different sized products, this is a huge time saver and simplifies the entire engraving process. If you engrave cups with handles this is the most efficient tool you can use. Many different attachments to choose from. Let you imagination run wild.

  11. Wade

    This grip is the greatest tool for laser engraving. Already saved me money because now I don’t have any mess-up’s at all.

    A must buy for anyone doing tumblers.

  12. Kathryn Ewers (verified owner)

    The day the grip was released I was teaching my high school classes. I had the kiddos jump online to help me snag one. I knew they’d sell out fast. I was one of the LUCKY ones who was able to order before they sold out within minutes.

    This is a game changer for my business. Every tumbler I’ve done is perfect. There’s no skewing, no guessing, and no trial and error. The grip is fool proof. It’s saved me so much time and money! It’s opened up the door to many possibilities for my laser business. I truly stand behind this amazing product and would be open to answering any questions about this amazing piece of equipment.
