MECHANIC Bull One Electric Glue Remover – High Torque OCA Screen Adhesive Removal Tool

Screen adhesive removal is where a lot of repair jobs go wrong. Push too hard with a blade and you crack the digitizer. Use a weak motor and the OCA glue just smears instead of lifting clean. The Bull One is built to fix exactly that problem — it gives you a motorized tool with enough torque to cut through hardened adhesive without needing to force anything against the glass. The core of the Bull One is its 3-in-1 shaft design. MECHANIC fixes a bearing, a brass cutting tip, and an aluminum alloy tip together using hydraulic pressing rather than a simple screw-fit. That matters on the bench because a loose or slightly off-center tip wobbles at high RPM and drags on the frame instead of cutting clean through the glue line. With the parts pressed into one concentric unit, the tip runs true, so your cutting path stays exactly where you position it — critical when you're working a millimeter away from an OLED panel. You get two speed settings, and they're built for two different jobs. Low speed delivers higher torque, which is what you need for hard, cured adhesive or battery glue that's had time to set. High speed is for clearing broad glue areas quickly, like when you're prepping a full back glass or a curved screen edge for separation — the motor moves fast enough to save time without adding pressure that could stress the panel. You adjust between them as the glue reacts, rather than committing to one setting for the whole job. Power comes from a built-in 1200mAh battery, charged through Type-C. That's enough runtime to get through several screen jobs in a row on your repair bench before you need to top it up, and the cable that ships in the box means you're not hunting for a charger. At 175g net weight, the tool sits comfortably in hand for the kind of repeated, controlled motion glue removal actually needs — you're not fighting tool weight while you're trying to keep a steady line along the display edge. In the box you get the Bull One unit, two needles, a hex wrench, and the Type-C charging cable — everything you need to start pulling glue the same day it arrives. The needles let you get into tighter spots around the frame where the main tip can't reach, and the hex wrench is there for tip adjustment and maintenance. Where this fits on your bench: it's the tool you reach for after you've heated the panel and before you get into full separation. Whether you're changing an iPhone display, replacing a curved AMOLED panel, pulling battery adhesive on a swollen battery job, or clearing OCA before a glass-only repair, the workflow is the same — heat, loosen, then run the Bull One along the bond line at the speed the adhesive calls for. It saves you the trial-and-error of doing this with a blade alone, and it protects the panel from the scratches and cracks that come from forcing a manual tool through set glue. For a repair shop doing regular screen and battery work, a dedicated glue motor like this earns its place fast — it cuts job time on every glue-heavy repair and reduces the panel damage that eats into your margins.
