Product details
Description
The Prasacco 20 Piece Micro Drill Bit Set is designed for high-precision drilling operations across a wide range of delicate materials. Crafted from high-hardness tungsten steel alloy, these micro drill bits offer exceptional wear resistance, durability, and rigidity during fine machining work. Featuring a nano-scale spiral cutting edge, each bit reduces cutting force to minimize tool breakage while delivering clean, burr-free holes.
Ideal for electronics hobbyists, PCB designers, jewelers, 3D printer enthusiasts, and CNC operators, this micro drill set contains 10 distinct sizes ranging from 0.3 millimeter to 1.2 millimeter (2 pieces per size). The bits feature standard 3.175 millimeter (1/8 inch) straight shanks that fit seamlessly into most rotary tools, CNC engravers, and micro hand drills. Color-coded positioning rings allow for rapid size identification and hassle-free bit selection.
Whether you are drilling printed circuit boards (FR-4), cleaning fine 3D printer nozzles, crafting custom jewelry, or engraving materials like plexiglass, amber, Bakelite, and soft plastics, this tungsten carbide micro bit set provides smooth chip removal and minimal drilling heat build-up.
How to use
- 1.
- Choose the required drill bit size using the color-coded positioning ring. 2.
- Secure the 3.175 millimeter shank into your CNC router, rotary tool, or micro hand drill chuck. 3.
- Set an appropriate rotation speed for your workpiece material, avoiding excessive lateral pressure to prevent bending the thin micro tip. 4.
- Lower the bit vertically into the material, allowing the spiral flute to naturally evacuate chips. 5.
- Clean off dust after use and place the bit back into the protective storage case.

ordering again for my workshop
this is my second time buying this exact micro drill set. the spiral flute design really helps with smooth chip removal when working on acrylic and plastics. last set lasted months before i accidentally snapped a couple using a shaky hand drill. solid quality.

pehle wale se behtar hai
mera purana local set bar bar bend ho jata tha project ke beech me, isliye yeh wala try kiya. tungsten steel material hone ki wajah se rigidity kaafi acchi hai aur heat bhi kam generate hoti hai drilling ke time. bas delivery thodi late mili baki sab badhiya hai.

Good for pcb drilling
bought this tungsten steel set for my diy circuit board project. bits are super sharp and make clean holes without any burrs. just need to be extra careful cause they are tiny and break easily if hand-drilled. packaging was ok.
FAQs
What materials can these micro drill bits penetrate?
These micro drill bits are designed for printed circuit boards (FR-4), acrylic, plexiglass, amber, beeswax, Bakelite, soft plastics, resin, and soft metals used in jewelry. They are not recommended for hard ferrous metals or stainless steel.
What shank size do these micro drill bits feature?
Each micro drill bit features a standard 3.175 millimeter (1/8 inch) straight shank, making them broadly compatible with standard CNC routers, PCB drilling rigs, and common rotary hand tools.
How do I prevent micro drill bits from snapping during operation?
Maintain a strictly vertical angle when drilling, use moderate feed rates with steady high rotation speed, and avoid applying sideways force. Allowing the sharp spiral edges to do the work minimizes stress on the micro tips.
