Hex Shank Titanium Countersink Drill Bit, Adjustable Wood Chamfer Screw Hole Drill Bit, Replaceable Titanium Twist Drill Bit for DIY Wood Furniture Carpentry Projects

2-in-1 Drilling & Countersinking Design Combines precision pilot drill and chamfer cutter to drill screw holes and form smooth countersink recesses at once. Eliminates two-step separate drilling & chamfer work, drastically boosting woodworking efficiency.

Wear-Resistant Titanium Coated Replaceable Drill Bit The twist drill core adopts full titanium plating for low friction, anti-rust and heat resistance. It cuts softwood, hardwood and plywood cleanly with no wood splitting. The drill is fully detachable for independent replacement, no need to discard the entire countersink body when the tip dulls.

Standard 1/4" Hex Shank for Universal Compatibility Six-sided hex shank delivers tight non-slip clamping force, compatible with all cordless drills, impact drivers and electric screwdrivers. No wobble during high-speed rotation for smooth, burr-free cuts.

Optional Adjustable Depth Limiter Ring Matching metal depth stop ring locks onto the bit to control countersink depth precisely. Every screw recess will be consistent, ideal for professional carpentry, cabinet making and mass DIY wood builds.

Solid High-Speed Steel Countersink Body Thickened high-hardness steel chamfer cutter body with golden anti-corrosion coating, resistant to deformation under heavy use. Sharp cutting edges maintain clean chamfers after thousands of holes.
