Complete guide: Disposable grip for Cobra 30mm
This disposable PEN-style grip is specifically manufactured for the Cobra tattoo machine, with a 30mm diameter. It uses a 30° bayonet connection instead of the classic multi-turn thread, ensuring a better fit on the machine and allowing needle depth adjustment "on the fly" by rotating the battery, without removing the grip from the machine. It comes individually packaged and sterile, together with the necessary adapter, and is manufactured in Sweden by Ink Machines. It fits both Neo cartridges and standard cartridge-type cartridges.
How to use
- Before opening, check that the sterile packaging is intact, undamaged, and unperforated.
- Open the packaging just before assembly, with clean hands or disposable gloves.
- Slide the grip onto the Cobra machine body and secure it via the 30° bayonet connection — a short twisting motion, no lengthy threading.
- Mount the included adapter if the cartridge type you are using requires it.
- Insert the cartridge, either Neo type or a standard one — the grip is compatible with both.
- Adjust the needle depth by rotating the machine battery, not the grip; the set depth remains memorized even if you later disassemble and reassemble the grip.
- Visually and manually check that there is no play between the grip and the machine body before starting work.
- After the session, dispose of the grip together with the used needle — it is single-use and cannot be resterilized.
Tips from us
- Before ordering, verify that your Cobra machine model uses exactly this type of 30° bayonet connection.
- Keep the grips unopened in a dry place, away from direct light, until the moment of assembly.
- If you frequently change needle depth during work, take advantage of the fact that adjustment is done from the battery — you don't need to stop and reassemble the grip.
- For long sessions, conventions, or guest spots, keep a few spare pieces on hand so you don't run out.
- When switching between Neo cartridges and standard cartridges, check the fit in the grip — the docking geometry differs slightly between the two types.
Warning: This is a SINGLE-USE product: do not resterilize or reuse on another client, regardless of disinfection. Do not use the grip if you notice that the sterile packaging is damaged, opened, or perforated. After use, dispose of it together with the needle according to the rules for sharps waste in your studio.
Frequently asked questions
Does this grip fit any tattoo machine, or only the Cobra?▾
It is specifically designed for the Cobra machine, with a 30° bayonet connection intended for this model. On other machines, the connection type may differ, so do not assume universal compatibility — first check the connector type on your machine.
What kind of cartridges can I use with this grip?▾
The grip is compatible with both Neo cartridges and standard (regular) cartridges. The difference is that Neo cartridges have a smoother and more secure 90° fit in the grip, compared to the 30° type of regular cartridges — both work, but the docking feel differs slightly.
How do I adjust the needle depth with this grip?▾
It is not adjusted from the grip, but by rotating the battery of the Cobra machine — this can be done "on the fly" without stopping work. An additional advantage: if you remove the grip and later reassemble it, the depth remains the same, and the battery and needle stay aligned.
Can I disinfect and reuse the grip to save money?▾
No. It is a single-use product, individually sterile packaged exactly for this purpose — it is used once, on one client, then discarded together with the needle. Disinfecting does not make it safe for reuse and violates standard biosecurity protocols in tattooing.
Why should I choose the 30mm diameter?▾
30mm is a common diameter for pen-style grips, offering a medium grip thickness — neither too thin nor too thick. The choice of diameter largely depends on hand size and personal grip preference, so if you are a beginner, it is a reasonable starting point.
Where does this grip come from and which brand produces it?▾
It is produced by Ink Machines and manufactured in Sweden. Each piece is individually and sterile packaged, together with the necessary adapter for mounting.

Frequently Asked Questions Is this grip exclusively compatible with the Cobra machine? Yes, this 30mm grip is specifically designed for the Cobra tattoo machine. Dimensions and geometry are optimized to ensure perfect attachment on this model. Use on other machines is not recommended as dimensional compatibility cannot be guaranteed. What advantages does the 30mm diameter offer? The 30mm diameter is considered the universal size in the tattoo industry. It offers an excellent compromise between the fine control of thin grips and the stability of thicker ones. It suits all working styles and most hand sizes, making it the most versatile choice. How is the grip mounted on the Cobra machine? Mounting is quick and simple: slide the grip onto the Cobra machine body until fully seated through controlled friction. Verify there is no play between grip and machine before starting work. No additional tools are required. Removal is done by simply pulling the grip off. Can I reuse this grip after disinfection? No, this grip is designed strictly for single use and must not be reused under any circumstances. The plastic material is not designed to withstand autoclave sterilization. Reuse represents a major cross-contamination risk and violates industry biosecurity protocols. Does the grip modify the Cobra machine vibrations? The disposable grip does not significantly modify the Cobra machine's vibration profile. The material absorbs minimal vibrations, potentially even slightly improving comfort. Correct attachment without play ensures vibrations transmitted to the hand remain consistent with standard machine use. How durable is the grip material during work? The medical-grade plastic material is durable enough to withstand a complete tattoo session without deformation or breaking. It is designed to maintain structural integrity throughout the duration of use. However, being single-use, it is not designed for repeated use or prolonged exposure to chemical substances. Is this grip suitable for beginners? Yes, the 30mm diameter is ideal for beginners as it provides a stable and comfortable hold. Being disposable, it simplifies the hygiene process for those who don't yet have experience with sterilization procedures. Beginners are recommended to start with this diameter before experimenting with other sizes. How many grips should I keep in stock? We recommend keeping sufficient stock for at least two weeks of activity. Calculate your average number of clients per day and add a 20% surplus for unforeseen situations. For studios with 3-5 artists, a minimum stock of 100 pieces is a solid starting point. Does the grip come with needles or must they be purchased separately? This product includes only the disposable grip, without needles or cartridges included. Needles and cartridges compatible with the Cobra machine must be purchased separately. Make sure to choose the needle configuration suitable for your desired working style and verify compatibility with your machine. How do I properly dispose of contaminated grips? Contaminated grips must be discarded in special sharps and contaminated medical waste containers. Do not mix them with regular household waste. Ensure your studio has a contract with an authorized company for biomedical waste collection and disposal, in accordance with current health regulations.
