Core Face Drill Defense
Attackers drill diagonally through the keyway plug to shear bottom pins. High-security cylinders embed diagonal sintered tungsten carbide pins (80 HRC).
Deflection Physics
- Diagonal Angle: Positioned at a $45^\circ$ angle flanking the key slot.
- Drill Destruction: Cobalt drill bits hitting the carbide pin experience immediate thermal glazing and tip shattering.
