Fast, Clean Countersinking

The 4-Cutter chamfer countersink bits feature M2 high-speed steel with nitrided treatment for smooth cutting and reduced vibration. They deliver a crisp 82-degree finish and work efficiently on softwood and hardwood. For very hard wood, consider shorter use cycles to maintain edge quality.

• 82-degree finish for flush, professional-looking holes
• Efficient performance on common softwood and hardwood species

Precision Self-Centering Drilling

Self-centering bits are built with a bevel guide, spring-loaded alignment, and dual side openings to minimize wobble. A steel housing with black zinc and brass guide adds durability, helping you start holes accurately for hinges and hardware placements.

• Bevel guide and spring-loaded alignment reduce drift
• Durable construction supports repeated use on cabinetry tasks

All-in-One Drilling Solution

Drill, countersink, and counterbore in a single step. Depth stop rings ensure consistent depth, and knurled screws allow fast HSS bit replacement—an efficient setup for repetitive or professional tasks where consistency matters.

• Depth stops promote uniform results
• Quick HSS bit changes support high-productivity workflows

Wide Range of Applications

The 1/4-inch hex shank fits most impact drivers, power drills, and bench drills. Ideal for cabinetry, hinges, drawer slides, shelves, and furniture projects. Use self-centering bits for alignment, then countersink bits for deeper pilot holes, all within the same kit.

With its organized case and practical bit assortment, this EZARC set is designed to be a dependable companion for both professional workshops and home garages, offering potential improvements in workflow, finish quality, and tool versatility.
