What the listings tell you, and what they leave out

All four listings state tungsten carbide or tungsten steel for the PCB bits, which is what you want for drilling copper-clad board without rapid wear. Three of the four include a pin vise hand drill; only the Lothee set is bits-only for a spindle or chuck you already own. Two listings state a 118 degree point angle, one states a pointed style, and one states nothing about the point. None states a warranty term, and none states a runout or tolerance figure, so buy on stated sizes and shank fit.

Buying guide: choosing the best pcb drill bit set

Match the diameter range to your work. Circuit board vias and component leads live between 0.1 and 1 mm, so a set that covers 0.1 to 1 mm handles boards; if you also drill enclosures or mounting holes, the wider 0.1 to 3.0 mm sets cover more. Check the shank: straight or round shanks fit a CNC spindle or rotary tool collet, while pin vise sets are for hand drilling. For more CNC tooling, see best CNC bit set for engraving and router bit set vs individual router bits.

Safety

Micro bits snap without warning. Wear eye protection, clamp the board, start the spindle before touching the work, and ventilate: fiberglass board dust is not something to breathe. See our dust mask vs respirator guide.

Project Match

  • Circuit board drilling on a CNC router: Lothee 60Pc Micro Bits, straight shank, 0.1 to 3.0 mm.
  • Fine vias and component leads: FAURAPMNG 40Pc PCB Bits, 0.1 to 1 mm in 10 sizes.
  • Hand drilling with a pin vise: SOKOSEY Pin Vise Set, 3-jaw chuck, 0.3 to 3.4 mm clamping.
  • Jewelry, crafts and occasional boards: Vinsot 95Pc Drill Set, twist plus PCB bits.

How the scores add up

Each set is scored out of 10 on performance, build, value, safety and warranty, with the weights published on our How We Pick page. A spec the listing does not publish scores nothing. None of these listings states a warranty term.

Product HQ Score Perf. /35 Build /25 Value /25 Safety /10 Warranty /5

Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score. Safety counts only for powered gear or where the listing states safety features; where it does not apply, the score is taken over the remaining 90 points.

FAQ: lasers and CNC

What size drill bits do I need for PCB drilling?

Component leads and vias typically need 0.1 to 1 mm. All four sets cover that range; the Lothee and SOKOSEY sets extend to 3.0 mm for mounting holes and enclosures.

Can I use these bits in a CNC router?

The Lothee listing states its bits are for CNC routers, and the SOKOSEY listing names CNC among the uses. Straight and round shank bits fit a spindle collet; pin vise sets are for hand use. See rotary tool vs CNC router for the machine choice.

Why tungsten carbide for PCB bits?

The listings state tungsten carbide or tungsten steel for the PCB bits, which resists wear from the glass fiber in FR-4 board far longer than plain steel. Three listings pair carbide PCB bits with alloy steel twist bits.

How do I keep tiny drill bits from breaking?

The Lothee listing notes its spiral edge reduces cutting force to prevent breakage. In practice: clamp the board, use a sacrificial backer, peck gently, and never side-load a 0.3 mm bit.

Do I need the pin vise?

Only for hand drilling. If you drill boards on a CNC router or drill press, the Lothee bits-only set skips the vise. The other three sets include one, with the SOKOSEY vise offering a 3-jaw chuck and 0.3 to 3.4 mm clamping range.
