Underfill glue is one of those jobs that separates a rushed repair from a clean one. Cut too aggressively around a CPU or NAND IC and you risk lifting pads or scratching the board; go too soft and the glue never clears fully, leaving your reflow or reballing job compromised before it even starts. The 2UUL DA17 Model Y Hand Finish Blade exists for exactly this step in your workflow — cutting stubborn underfill black glue away from the motherboard surface without damaging the PCB itself.
Each blade in this pack is polished by hand, not machine-stamped in bulk. 2UUL's process leans on technicians with years of hands-on repair experience to grind and finish every edge, which is why the cutting line stays smooth and consistently sharp instead of uneven like you get with mass-produced blades. The edge profile runs thin at the tip and thickens gradually toward the body, so as you push the blade under the glue line, the force spreads more evenly across the contact point instead of concentrating pressure in one spot. That's what keeps your board safe when you're working close to fine pitch components.
Model Y specifically is shaped for cutting underfill black glue clean off the board without catching on solder mask or lifting nearby components. If your bench work involves IC change karna on boards with heavy underfill coating — common on Samsung, Oppo, Vivo, Infinix, and Tecno boards coming in for dead phone, hang on logo, or charging issue complaints — this blade handles the glue clearance step before you move to jumper lagana or reflow. It sits well alongside your S, E, and X model blades from the same 2UUL SEXY series if you're building out a complete underfill toolkit, since each model targets a slightly different cutting angle and glue type.
This pack ships without handle, which keeps the price down for technicians who already run a 2UUL blade holder or handle from an earlier purchase. If you're setting up a bench from scratch, pair it with a 2UUL handle set separately rather than buying blade-only packs across every model. The 4 blades per pack give you enough working stock to get through a normal week of underfill jobs before you need to resharpen or replace.
One thing worth knowing about hand-polished blades like this — the edge does dull with heavy daily use, especially on boards with thick or aged glue. The blade is built to allow repeat grinding, so rather than tossing it after a few uses, you can touch up the edge on a fine stone and get more life out of each piece. That's a real cost saving over a busy repair season compared to disposable blade sets that go blunt and get binned after a handful of jobs.
For a service center or repair shop juggling multiple technicians on the bench, having dedicated Model Y blades on hand means nobody has to reach for a generic box cutter or worn-out blade when underfill glue removal comes up. It's a small tool, but it directly affects your yield on CPU and IC repair jobs — a clean cut here saves you from board damage that turns a simple glue removal into an expensive PCB repair. Keep a few packs stocked at your workshop so blade wear never holds up a job mid-repair.
Whether you're running a solo repair counter or a full service center floor, this blade fits into your existing underfill workflow without needing any change in technique — just a cleaner, more controlled cut where it matters most.
