Applications & Features:
--- Suitable for milling printed circuit boards, PCB, MDF, ABS, PVC, acrylic, nylon, plastic, wood, fiber glass, carbon fiber, density board, plasterboard, etc. Use on CNC milling machines. Sharp cutting edge provides smooth cutting and no glitches. Great replacements for your CNC or PCB machinery.
--- Pin-driven positive locking with quick-change feature helps prevent the hole saw from locking on the spindle, ensuring smooth, worry-free operation. The hex shank grips the chuck or extension adapter securely and increases torque transmission, reducing slippage.
--- To use, simply insert the hole saw into the mandrel, hold it in place, and attach it to the drill chuck. Applying moderate pressure while rotating at the appropriate speed allows the sturdy mandrel and high-speed steel cutting edges to create clean, precise holes.

Useful Tips:
--- Ensure that the hole saw is securely attached to the arbor before operation.
