Improve drilling precision with this adjustable depth limiter. Built for consistent results, it helps you drill to the exact depth every time. Key features Precise depth control: Automatically stops the drill at your chosen depth for clean, repeatable holes and reduced risk of overpenetration. Durable, lightweight construction: Aluminum alloy outer rings offer strength and a polished look; nylon inner rings provide smooth, secure locking with less wear on the locking surface. Secure, antislip tightening: Antiskid lines on the stopper surface ensure a firm grip when tightening, so settings stay put during work. Adjustable inner diameter: Multiple fixed positions accommodate different bit shanks and positions; clamp firmly at the selected setting. Broad compatibility: Designed to work with most standard drills and depthstop configurations. Practical performance: Improves hole quality, increases workflow efficiency, and extends the life of the drill's locking mechanism. Typical use scenarios Furniture and cabinetry: set exact screw and dowel depths for precise joints. Repetitive drilling: reproduce identical depths across a batch of pieces in woodworking or metal fabrication. Electronics enclosures and plastic parts: prevent throughholes and protect delicate materials. Materials and size Outer rings: aluminum alloy; inner rings: nylon; compact, lightweight, and durable.
