Description

Take the guesswork out of drilling. Whether you are installing dowels, assembling flat-pack furniture, or working on delicate cabinetry, precision is key. This 8-piece Drill Bit Limit Ring Set allows you to set a hard stop on your bits, ensuring consistent hole depths across your entire project.²

Made from hardened carbon steel, these rings are designed to stay firmly in place without slipping, even under high-speed drilling. The set covers almost every common drill bit size from 3mm to 16mm, making it compatible with standard twist bits, brad-point bits, and masonry bits.³ The included hex wrench allows for quick adjustments, so you can move from one task to the next with professional accuracy and zero "over-drilling" mistakes.⁴

⭐ Key Features

• Full Range of Sizes: Includes 8 different collars ($3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm, 16mm$) to fit virtually any standard drill bit set.

• Positive Locking Power: Features a grub screw design that bites securely onto the drill bit, preventing the ring from sliding up or down during use.

• Prevents Surface Damage: Ideal for blind holes where you need to stop just before the surface, protecting your furniture and worktops from through-holes.

• Durable Carbon Steel: Heat-treated for strength and finished with an anti-rust coating for a long service life in your toolbox.

• Hex Key Included: Comes with the specific small wrench needed for the set screws, ensuring you have everything you need to start immediately.

💡 Top Tips for Best Results

1. Double Check: Always measure from the tip of the bit to the bottom of the ring using a ruler or depth gauge before you start drilling.

2. Tighten Firmly: Ensure the grub screw is tightened against the "land" (the flat part) of the bit's flute for the most secure grip.

3. Clean Bits: Wipe excess oil or dust off your drill bit before applying the ring to prevent it from sliding.
