00:00Single Flute VS Ball Nose End Mills, Which Cuts Acrylic?
00:04Quick question I get a lot, Single Flute or Ball Nose, Which One Actually Cuts Acrylic?
00:09I dug through the listings, compared prices, and pulled out the best deals for Single Flute
00:14VS Ball Nose End Mills, Which Cuts Acrylic. Short version, Single Flute Wins, Every Time,
00:20With Acrylic. Starting with this one, a One Piece AAA Single Flute Carbide Spiral End Mill,
00:26and the same listing covers 3.175, 4, 5, and 6mm shanks. That DLC coating is the real story here,
00:34less friction, less heat, so the edge stays sharp instead of gumming up in acrylic.
00:39393, almost 5,000 sold, rated 4.9. That's the do-everything bit, flat cuts, slots, 2D, and light
00:473D. This Drianique Single Flute Spiral is the same idea, a bit cheaper at 312, and it's the one I
00:54keep
00:54recommending to beginners. Nearly 4,700 sold, still 4.9 stars, which tells you plenty for something
01:02this cheap. Single Flute means two edges total, so it's stiff and it doesn't rub. Buy this one if
01:09you're cutting acrylic sheets all day and don't want to overspend. Now the set, five pieces from
01:14start now, 16-18, and every bit is a single-edge spiral that both drills and mills. That's the trick,
01:20the pointed spiral tip starts the hole in acrylic without walking or cracking it,
01:25then you switch into the mill and keep going. Five bits for about $3.24 each, and it holds a
01:30straight five-star rating. Best value if you want a drawer full instead of a single tool.
01:37Another Drianique, and this is the cheapest of the bunch at $2.93.
01:41Same Single Flute Spiral design, and the listing calls out acrylic, wood, and ACM exactly the soft
01:47plastics and composites where single flute shines. $27.50 sold, 4.9 stars. Honestly,
01:55for a first acrylic bit or a backup, this is the one to click. Skipped, ball-nose product paragraph,
02:02none in given list. Add when list includes a ball-nose bit. Cut, spec repetition, spec dumps,
02:09safety disclaimers, add a chip jam slash venting line if asked for a machining tutorial.
