10pcs Cleaning Nozzle Drill Kit 0.1mm to 1mm - 3D Printer & PCB Precision Bits

Specifications

• Material: Tungsten Steel (Carbide)

• Sizes Included: 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm

• Shank Diameter: ~3.175mm (Standard universal fit)

• Quantity: 10 pieces per box

• Color-Coding: Randomly assigned color rings for size identification

Key Applications & Projects

• 3D Printer Maintenance: Clearing clogs in 0.2mm, 0.4mm, and larger nozzles.

• PCB Manufacturing: Drilling precision via-holes and component through-holes.

• Jewelry Making: Micro-drilling in soft metals and resin.

• CNC Engraving: High-detail carving on plastic or wood.

Unlock New Capabilities (Project Evolution)

• Feature Upgrade: Traditional "acupuncture needle" cleaners can only push clogs; these drill bits remove the material, restoring the internal geometry of the nozzle.

• Effort Level: Intermediate. Requires a steady hand and proper nozzle heating for 3D printer maintenance to avoid bit breakage.

ACCESSORIES 

• 10 x Precision Drill Bits (Sizes 0.1mm through 1.0mm)

• 1 x Plastic Storage Case (Random color/style)

FREQUENTLY ASKED QUESTIONS (FAQ)

1. Can I use these on a cold 3D printer nozzle? No, always heat your nozzle to the filament's printing temperature before using these drills to avoid snapping the bit.

2. Are these bits fragile? Yes, sizes below 0.4mm are extremely delicate and should be used with minimal vertical pressure.

3. Will they fit a Dremel? Yes, the standard 3.175mm shank fits most rotary tools and CNC spindles.

4. What material are they made of? They are made of high-hardness tungsten steel (carbide).

5. Do the colors signify specific sizes? No, the ring colors are randomly assigned but help you differentiate between the bits in your set.

6. Can I use these on hardened steel nozzles? Yes, but they are most effective on brass and stainless steel.

7. What is the shank diameter? It is approximately 3.175mm.

8. How do I clean the bits after use? Use a soft brush or compressed air; avoid harsh chemicals that might degrade the color rings.

9. Can these drill through aluminum? Yes, tungsten steel can handle aluminum, copper, and soft plastics easily.

10. How do I prevent the bits from snapping? Use a vertical entry and exit; never tilt the drill while it is inside the nozzle or PCB.

11. Are the sizes marked on the bits? Most micro-bits of this type are not marked; use the color rings to keep them in order.

12. Are they suitable for manual use? Yes, they can be used with a pin vise or a small hand-drilling tool.

13. Is there a duplicate size in the box? No, the set contains one of each size from 0.1mm to 1.0mm.

14. What is the storage box like? It is a clear plastic flip-top box designed to keep the bits safe from impact.

15. Can I use these for wood carving? Yes, they work well for high-detail micro-carving in wood.

16. Are these "twist" drills? Yes, they are micro-twist drill bits.

17. Can I use them on glass? No, these are not designed for glass or masonry.

18. What should I do if a bit gets stuck? Gently heat the area further and use pliers to pull it out vertically; do not wiggle it.

19. Are they for hobbyist or professional use? Both; they are standard tools for pro PCB labs and 3D printing enthusiasts.

20. Can I buy individual sizes? This SKU is a 10-piece set; individual replacements are sold separately.
