7-Piece Countersink Drill Bit Set with Aluminum Alloy Stop Collar, Screwdriver Bit & HSS M2 Tapered Bits, 1/4" Hex Shank Drilling Kit for Woodworking
8 sold in last 24 hours
- Aluminum Alloy Construction + Bearing-Equipped Stop Collar Built with an aluminum alloy body and aluminum alloy stop collar (lightweight yet durable), the stop collar adds a built-in bearing: this reduces friction during use, making countersinking smoother (no jittering) while boosting the collar’s long-term wear resistance.
- Quick-Change Bit Design + Targeted Size Set This 7-piece kit (1/8”–3/16” sizes, paired with 3/8”/1/2” 82° countersinks) features a fast-bit replacement design — swap bits in seconds without extra tools, cutting down on downtime mid-project. It also includes a 1/4” hex shank for slip-free drill grip, so you can focus on the task instead of fumbling with parts.
- Bumper Plate Emergency Stop: Safe, Over-Drill Protection Equipped with a bumper plate emergency stop function: once the stop collar touches the workpiece surface, it halts drilling instantly — eliminating over-drilling risks and ensuring consistent, clean countersink depths every time.
- 82° Standard Angle: Works Across Materials & Tasks Designed with an 82° countersink angle, this set handles wood, plywood, MDF, particleboard, plastic, and drywall seamlessly. Its sturdy alloy cutting edges (paired with the smooth-bearing collar) deliver crisp, ragged-edge-free results for both DIY projects and professional woodworking.
- Compact 250g Storage Case: Organized & Portable All bits, the hex wrench, and depth-control components fit neatly into a lightweight (≈250g) labeled storage case. Grab the right tool fast (no more lost parts) — it’s small enough to toss in a toolbag for job sites, or stow in a home workshop cabinet.
