2UUL SD24 4-in-1 Screwdriver Bit storage Set

Four tips, one magnetic column. The SD24 holds the four blades a phone repair actually needs — Pentalobe 0.8 mm, Phillips 1.2 / 1.5 mm, Tri-Point 0.6 mm and Convex Cross 2.5 mm — in a compact green holder with magnetic retention and a latch design that keeps each bit seated till you pull it. The bits are S2 high-hardness alloy steel: precision-ground, hard, and rebuilt to the exact profile that opens modern devices.

• Magnetic 4-slot storage — each bit is held magnetically in its own channel, so blades stay put in a drawer, a bag or a pocket and come out only when you pull them.
• Latch design — a leaf-spring detent on each shank locks the bit into position; it clicks in and stays seated until you deliberately remove it.
• S2 high-hardness alloy steel — the blades are S2 precision bits, chosen for hardness and tip retention, so the profile survives real torque instead of rounding off.
• The four tips that actually get used — Pentalobe 0.8 mm, Phillips 1.2 / 1.5 mm, Tri-Point 0.6 mm, Convex Cross 2.5 mm. The same four families 2UUL builds its KAKA drivers around.
• Fits 4 mm (M4) shank drivers — standard 4 mm hex shank bits, so they drop straight into the KAKA torque screwdriver handle and most precision drivers.
• 23.5 g, 52 mm tall — small enough to live in a tool pouch or a shirt pocket, big enough that you stop losing blades in the tray.
• Retail-packed as a 4-piece set — holder plus four blades, 86 × 50 × 23 mm box, ready to ship and easy to stack as an add-on item.
