Sterile and single-use packaged product.
Kwadron RM (Round Magnum) long bar needles are the highest quality traditional curved magnum needles, designed for fluid shading with coil and rotary grip machines. The Round Magnum configuration arranges needles in a curved fan formation across two rows, welded to the long bar. The needle curvature allows uniform ink distribution with soft transitions and reduced trauma — the characteristic that made RM the world standard for quality shading. Manufactured in Poland from 316L surgical stainless steel with Kwadron's premium finish, these needles deliver world-class consistency and performance. The long bar mounts into the machine grip via corresponding tube. EO gas sterilization and individual packaging guarantee safety. Like all bar needles, sterilization responsibility for reusable equipment belongs to the artist. Available in configurations from 7RM to 23RM and above, these needles are the classic instrument for portraits, black and grey, and realism done with coil machines. Kwadron RM long bar offers the traditional feel of the coil shader — an experience many top artists prefer over modern pens. Kwadron long bar needles are manufactured with the same quality standard as cartridges — the same 316L steel, the same polishing process, the same quality controls. The difference is exclusively in the mounting format: long bar for grip and tube vs. cartridge body with membrane for pens. Artists working with coil machines particularly appreciate Kwadron's constant quality — every needle performs identically, eliminating variables that can affect work quality mid-session. Packages of 50 pieces offer excellent value for active studios.
Frequently Asked Questions
What advantage does a coil machine with Kwadron RM long bar offer over a pen with cartridge?
A coil shader machine with Kwadron RM long bar offers: direct haptic feedback allowing exact penetration feel, superior stroke control through spring and contact screw adjustment, constant power without battery, and a classic shading feel that many top artists consider superior to modern pens.
What tubes do you recommend for Kwadron RM long bar?
For Kwadron RM long bar, use magnum (flat tip) tubes from surgical stainless steel. Tube size must exactly match the configuration: medium flat tubes for 7RM-11RM, and large flat tubes for 13RM-23RM. Premium tubes have tight tolerances ensuring needle stability and clean transitions without unwanted vibrations.
Is Kwadron RM long bar better for portraits than RM cartridges?
It is not necessarily better, but different. Kwadron RM long bar with a coil shader machine offers a haptic control and feeling that some artists prefer. RM cartridges with pens offer convenience, speed, and safety membrane. Kwadron needle quality is identical in both formats. The choice depends on personal preference and artist experience.
What Kwadron RM long bar configuration is most versatile?
The most versatile configurations are 9RM and 11RM — they cover most shading needs. 9RM offers excellent control for medium areas and details, 11RM is ideal for larger surfaces and wide transitions. Together, these two configurations satisfy 80% of shading needs. Add 7RM for fine details and 15RM for backgrounds.
How do I adjust the coil shader machine for optimal shading with Kwadron RM?
For optimal shading with Kwadron RM on a coil shader: set a longer stroke than for lining (3.5-4mm), adjust the contact screw for moderate speed, set voltage to 7-10V, and adjust the spring for slower rebound. The needle should extend 1.5-2mm from the tube. These adjustments produce a smooth, controlled shading motion.
Are Kwadron RM long bar needles available in 0.25mm too?
Yes, Kwadron RM long bar is available in needle diameters of 0.25mm (#8), 0.30mm (#10), and 0.35mm (#12). 0.25mm is ideal for ultra-fine shading and delicate realism with a coil machine. 0.30mm is the most versatile standard. 0.35mm is preferred for dense saturation and color packing with a shader machine.
Does Kwadron RM long bar work well with grey wash?
Excellently. The coil shader machine + Kwadron RM long bar + grey wash combination is the classic configuration for top black and grey work. The coil machine's haptic control allows very fine pressure and speed adjustments, and Kwadron needle quality ensures clean transitions with diluted ink. Many legendary black and grey artists use exactly this combination.
How much do Kwadron RM long bar needles cost compared to cartridges?
Kwadron RM long bar needles have a lower per-needle cost than equivalent cartridges, as they do not include the plastic cartridge body and membrane. However, total cost also includes tubes (reusable but with initial investment) and autoclave sterilization costs. Long-term, bar needles are more economical for high-volume studios.
What maintenance does a coil shader machine need for optimal performance?
A coil shader machine needs: cleaning and disinfection after every session, regular spring inspection (replace at signs of fatigue), contact screw lubrication, electrical connection checks, and coil inspection for overheating signs. A well-maintained machine delivers consistent performance for years. Invest in preventive maintenance.
Can I alternate between Kwadron RM long bar and cartridges in the same session?
Technically, you can use a coil machine with long bar needles and a pen with cartridges in the same session, alternating between them. However, this practice is less practical — it requires two machines prepared simultaneously and protective equipment for both. Most artists choose one system and use it consistently throughout the entire session.
