Precise and Efficient: Once the stop ring is fixed on the drill bit, it will not shift. Helps you drill multiple holes quickly and easily to a consistent, precise depth. Solves the problem of your repeated deep drilling or drilling too deep. No more wrapping tape around your drill bits to control depth, saving time and achieving greater accuracy.
Durable Material: Made of high-quality carbon steel for good durability. The surface is blackened with anti-rust oil to enhance anti-rust performance. Safe and sturdy, the screw-type collar will not damage the drill bit.
Easy to Use: Each stop ring has a locking screw that allows it to be securely locked in any position on the drill bit, and the included hex wrench makes it easy to tighten and adjust quickly and easily, accurately controlling the depth of the hole you are drilling.
