Mozeyerh 5-Piece Countersink Drill Bit Set – HSS M2, Low Friction Depth Stop, 82° Counter-Bore, 1/4" Hex Shank

Precision and versatility in a compact set

The Mozeyerh 5-piece countersink drill bit set is designed to deliver clean, precise holes for common woodworking tasks while keeping your toolbox tidy. Each bit features a tapered M2 high-speed steel body and a sharp cutting edge that helps you create neat pilot holes and flush countersinks without wandering.

Included are five pieces that cover a range of sizes for pilot drilling and 82-degree counter-bore operations. The set includes 1/8", 9/64" and 11/64" pilot bits paired with 3/8" 82° counter-bore and 3/16" drill plus 1/2" 82° counter bore, along with a 1/4" hex shank for universal compatibility with most drills. A depth stop allows you to dial in the exact depth you need, while the attached plastic collar helps minimize surface marring on delicate surfaces.

The combination of HSS M2 material and spiral chip flute ensures efficient material removal, producing smoother edges and more consistent results across natural woods, plywood, fiberboard, drywall, and certain plastics. For best results, operate the countersink at slow speeds—around 200 RPM—and let the set do the work with measured steps rather than forceful stabbing.

What makes the Mozeyerh set stand out

• Depth adjustable: Set the stop to your preferred drilling depth for repeatable outcomes.
• Low-friction action: The tapered bits and chip flute design reduce heat buildup and chatter.
• Surface protection: The included plastic collar helps reduce surface marring during countersinking.
• Comprehensive kit: Five precision bits, an Allen wrench, and a plastics collar fit the included carrying case for easy storage.

Versatility in one compact package means you can tackle furniture repair, cabinetry work, and DIY builds with greater confidence. The case weighs just about 250 g, and its hanging hole design keeps it within reach in a workshop or on a pegboard. The set is suitable for wood-based materials like natural wood, chipboard, plywood, MDF, decking, drywall, and even some plastic boards. When selecting the bit, match the diameter and countersink angle to your screw size to achieve a flush fit for your project.

Tips for best results

• Use the depth stop to regulate depth and avoid through-holes where not wanted.
• Start with a pilot hole before countersinking and finish with a light pass to smooth edges.
• Keep RPM around 200 for steady, controlled cutting and reduced heat.
