2 Pcs Drill Depth Stop Collar Set, Adjustable Aluminum Drill Bit Stopper with Protective Nylon Inner Ring, Fits 5/64"-7/16" Bits, Precision Depth Controller for Woodworking & Plastics

Upgrade Your Woodworking Precision with Our Protective Drill Stop Collar SetAchieve consistent hole depths while effectively reducing wear on your drill bits. Our Aluminum Alloy Drill Depth Stop is designed with a unique nylon inner ring acting as a buffer, making it a practical companion for delicate woodworking and DIY projects.📐 Key Specifications:Material: Lightweight Aluminum Alloy Shell + Nylon Locking Inner RingSmall Collar Range: 5/64" - 3/16" (0.078" - 0.18")Large Collar Range: 15/64" - 7/16" (0.23" - 0.43")Dimensions: Small (0.79" H x 1.18" W), Large (1.34" H x 1.10" W)⚠️ Important Usage Notes (Please Read Before Purchase):Wood & Plastic Only: This tool is engineered for materials with consistent resistance. Do NOT use on metal. The sudden torque when piercing metal will overcome the nylon ring's friction, causing slippage, friction-induced melting, or damage to the plastic inner ring.Depth Consideration: To maintain straightness and stability, the collar has a robust height (up to 1.34"). When used with standard short bits, it will occupy a significant portion of the length. It is intended for shallow to medium depth drilling only.Pro Tip for Tiny Bits: For bits at the absolute minimum size limit (e.g., 5/64"), adding a small piece of painter's tape to the bit shank will dramatically increase the nylon ring's grip and prevent spinning.✨ Why Choose This Design?Traditional metal collars use grub screws that directly bite into your drill bits, leaving permanent burrs and deep scratches. Our twist-to-lock nylon ring design acts as a protective layer, effectively reducing metal-to-metal abrasion. Plus, the lightweight aluminum body won't throw off the balance of your drill.📦 What's in the Box?1 x Small Drill Bit Stop Collar1 x Large Drill Bit Stop Collar

• PROTECTIVE NYLON INNER RING: Unlike all-metal stops that directly grind against expensive bits, our collar features a built-in nylon locking ring. It acts as a cushion to securely hug the bit, effectively preventing metal-to-metal scratches and protecting the integrity of your drill bit surface.
• IDEAL FOR SHALLOW TO MEDIUM HOLES: Designed for precision and stability. Note: The collar's robust height ensures straight rotation but will occupy a portion of the bit's length. Therefore, it is highly recommended for shallow to medium-depth drilling rather than deep holes.
• OPTIMIZED FOR WOOD & PLASTIC (NOT FOR METAL): Engineered specifically for woodworking, acrylics, and plastics. ⚠️ IMPORTANT: Do not use on metal. Drilling metal creates extreme torque that easily causes the nylon ring to slip or sustain irreversible wear and tear.
• WIDE COMPATIBILITY & PRO TIP: Includes two collars fitting 5/64"-3/16" and 15/64"-7/16". PRO TIP: When using extreme small bits (like 5/64") at the limit of the range, wrap a tiny piece of painter's tape around the bit shank before clamping. This significantly enhances the friction for a more reliable grip.
• LIGHTWEIGHT ALUMINUM BODY: The outer shell is crafted from lightweight aluminum alloy, preventing top-heavy imbalance on your drill. Easy to lock and unlock with a simple twist, it offers a practical balance of bit protection and depth control.
