• DOUBLE GRUB SCREW DESIGN FOR SECURE LOCKING — Features two tightening screws instead of one, providing significantly stronger clamping force than single-screw collars. Prevents slipping, falling off, or shifting during high-speed drilling operations — a common complaint with cheaper alternatives .
• COMPLETE 12-SIZE SET FOR ANY DRILL BIT — Includes 12 inner diameter sizes: 3,4,5,6,7,8,9,9.5,10,12,14,16mm. The 9.5mm (3/8 inch) size is particularly useful for standard imperial drill bits. Covers virtually all common drill bit diameters for woodworking and home improvement projects .
• PREMIUM 304 STAINLESS STEEL CONSTRUCTION — Made from high-quality 304 stainless steel with excellent heat resistance, corrosion resistance, and wear resistance. Won't rust or deform even after prolonged use in demanding woodworking environments. More durable than aluminum or plastic alternatives .
• EASY TO INSTALL AND ADJUST — Simply slide the collar onto your drill bit, position it at your desired depth, and tighten the two screws with the included hex wrench. No special tools or skills required. Allows quick adjustments between different drilling depths without removing the collar from the bit .
• PREVENTS OVER DRILLING FOR PROFESSIONAL RESULTS — Accurately limits drilling depth to ensure consistent hole depths across multiple workpieces. Eliminates guesswork and prevents accidentally drilling through your material. Ideal for furniture assembly, hinge installation, doweling, and any project requiring repeatable depth control .
