Precise depth control: drill bit depth stop lets you set and hold an exact drilling depth so holes are consistent and workpiece integrity is preserved. Easy to adjust and secure: the collar’s inner diameter is adjustable and can be fixed at different positions along the drill bit to control depth accurately. Non-slip, manual tightening: textured surface provides a secure, non-slip grip so you can tighten the stop by hand without tools for quick setup and removal. Broad material compatibility: designed for use on ordinary tiles, wood, metal, plastic and brick, making it suitable for a wide range of projects. Practical for common installations: useful for furniture installation and other tasks where repeatable hole depth matters. How this helps you Reduce mistakes and rework by drilling to the same depth every time. Protect finished surfaces and fasteners by preventing over‑drilling. Speed up repetitive drilling tasks with a simple, tool-free stop that clamps onto the bit. Typical use scenarios 1. Furniture installation: set the stop to the exact depth for pilot holes or screws to avoid splitting or misaligned fasteners. 2. Tile or masonry anchoring: control depth when drilling into tiles or brick to ensure anchors seat correctly without through‑penetration. 3. General workshop tasks: use on wood, metal or plastic for consistent pilot holes, dowel holes, or when preparing parts for assembly. Features at a glance Function: drill depth stop / collar / stop ring for controlling drilling depth Operation: manually tightened with a non‑slip textured surface Compatibility: works with drill bits used for ordinary tiles, wood, metal, plastic and brick Adjustment: inner diameter can be adjusted and fixed at multiple positions along the bit Simple, reliable and easy to use for any job that needs consistent drilling depth.
