• PROTECTIVE NYLON RING DESIGN: Built with a cushioned nylon inner ring that securely grips bits. Unlike all-metal stops, this design significantly reduces the risk of metal-to-metal scratches, helping to protect your expensive drill bits from everyday wear and tear.
• FOR SHALLOW & MEDIUM DEPTHS: Features a robust aluminum body for stability. Note: The collar's height will occupy a portion of your bit's length, making it ideal for precision shallow or medium holes.
• WOOD & PLASTIC ONLY: Specifically engineered for woodworking, PVC, and acrylics. ⚠️ DO NOT USE ON METAL. High torque on metal will cause slippage or permanently damage the nylon ring.
• SIZE RANGE & PRO TIP: Includes 2 collars (5/64"-3/16" & 15/64"-7/16"). PRO TIP: When using the smallest 5/64" bit, wrap a tiny piece of painter's tape on the bit shank to maximize grip and prevent spinning.
• LIGHTWEIGHT & BALANCED: Crafted from premium aluminum alloy, ensuring it won't add top-heavy weight to your drill. Features an easy twist-to-lock mechanism for fast adjustments.
