Countersink Drill Bit Set with Depth Stop, 1/4" Quick Change Hex Shank, Aluminum Alloy Stop Collar, HSS M2 Bits Head & Hex Wrench, Counter Sink Drill Bit for Wood for Wood, Plastic, Woodworking

This wood countersink drill bit set includes 4 bits (2.8×8mm, 3.2×8mm, 3.5×10mm, 4×10mm) , 1/4" hex shanks, and a hex wrench. Features TOUCH-STOP TECHNOLOGY: aluminum limit ring with bearing stops over-drilling, reduces friction. HSS M2 4-blade bits stay sharp; adjustable aluminum depth stop (via hex wrench) offers precise control. Spiral flutes enable fast chip removal, avoiding clogging. Suitable for woodworking (natural wood, MDF, plywood, etc.), not for metal. Operate at ~200 RPM for best results.

• TOUCH-STOP TECHNOLOGY: Features an aluminum limit ring with built-in bearing that instantly stops drilling upon contact with wood, preventing over-drilling and ensuring consistent depth control. The smooth-bearing design reduces friction for effortless operation.
• PACKAGE CONTENT: The countersink drill bit set for wood includes 4 different sizes countersink drill bit: 2.8 x 8 mm, 3.2 x 8 mm, 3.5 x 10 mm, 4 x 10 mm (all with 3/8" 82° countersink holes and 1/4" hex shanks), and a hex wrench.
• ADJUSTABLE DEPTH: High-speed steel HSS M2 4-blade drill bits stay sharper longer, while the aluminum depth stop (with bearing) resists wear better than plastic stops. Easily adjust drilling depth with the included hex wrench. The upgraded aluminum collar provides clearer markings and tighter precision for flawless countersunk holes.
• FAST CHIP REMOVAL: The spiral-fluted design of these counter sink drill bits efficiently clears wood chips outward, preventing debris buildup and eliminating clogging for smoother drilling. Ideal for woodworking, cabinetry and DIY projects.
• WIDE APPLICATION: This countersink drill bit set is designed for woodworking applications, including natural wood, solid wood boards, particleboard, MDF, plywood, and synthetic fiberboard. For optimal performance and clean edges, we recommend operating at a low speed of around 200 RPM. Note: Not suitable for metal or sheet steel drilling.
