00:00If you've ever watched a perfectly good PCB or a piece of walnut get chewed up by a dull,
00:04wobbly engraving bit, you know that pain. I've been down that rabbit hole,
00:09buying cheap bits that snap on the third pass, and honestly, it almost made me quit
00:13engraving altogether. So I went digging and rounded up the 5 best CNC engraving bits for
00:18precision milling, the ones people are actually buying by the thousands, and I found some
00:22seriously good deals on all of them. Let's get into it.
00:27First up is the classic PCB engraving bit with the 3.175mm shank, and this is the one I keep
00:33reaching for. It's a V-shaped carbide bit that comes in angles from 10 all the way up to 90
00:38degrees,
00:39with tip sizes of 0.1, 0.2, and 0.3mm. That tiny 0.1 tip is the star here,
00:47it's what lets you isolate traces on a circuit board without bleeding into the next pad.
00:52It's sitting at $7.65, nearly 5,000 sold, and a 4.9 rating. For under 8 bucks, this is
01:00the safest
01:00first buy in the whole lineup. Next is the Chowmaster PCB milling cutter,
01:06and this is the budget pick that punches way above its weight. You get the full angle range 10, 15,
01:1220, 30, 45, 60, and 90 degrees on a 1⁄8-inch shank, and the big difference is that tin coating,
01:18that gold-colored titanium nitrite layer. It genuinely cuts down heat and friction,
01:24so the edge stays sharp noticeably longer, especially in hardwood.
01:28And the price? $3.29. That's it. At that price you can grab a handful,
01:36keep spares in the drawer, and stop babying every single cut. Now if you're running a 4mm collet,
01:42the XCAN 3-inch pyramid engraving bit is the one you want. Three cutting edges instead of one means
01:49the load gets shared, so you get a cleaner finish, less chatter, and a bit that just doesn't wander on
01:54you. It comes in 20 through 90 degrees, solid carbide, and it's rated a perfect 5 stars across
02:00nearly 4,800 sales. At $20.42 it's not the cheapest here, but this is a tool that survives
02:07production work instead of dying after one project. If you'd rather buy once and be done,
02:13take a look at the 10-piece 3-inch PCB engraving bit set with the 3.175 shank.
02:18You get the whole spread 20, 30, 40, 45, 60, and 90 degrees, plus the 0.1, 0.2,
02:25and 0.3mm tips, all in one box. The reason I like a set like this is that you stop
02:32guessing.
02:33You just grab the angle that matches your job instead of forcing the wrong bit and ruining
02:37the workpiece. It's $31.68 with a 4.8 rating, which works out to about 3 bucks a bit.
02:45And finally, my personal value pick, the 10-piece pyramid engraving bit set on the 1-8-inch shank.
02:51Same 3-inch pyramid geometry, same 20- to 90-degree range, but you're paying $11.97 for the whole
02:58set.
03:00That's basically $1.20 a bit. It's rated a full 5 stars with over 4,000 sold,
03:06and people keep saying the same thing, they hold up way better than the price suggests.
03:10If you're setting up a new machine or you just want a full angle range without the sting,
03:14start here. All 5 of these are linked down in the description,
03:18so go check the current prices, a couple of them move around quite a bit.
