OCGIG 4pc Countersink Chamfer Tool Set – HSS 4241 Deburring Bits for Metal, Wood & Plastic

Overview: Precision you can trust

The OCGIG 4pc Countersink Chamfer Tool Set is built with high speed steel HSS (4241) to deliver clean, repeatable edges on metal, wood, and plastic. Each bit is designed to create sharp, controlled chamfers, making it easier to start holes, deburr edges, and prep surfaces for fasteners.

What’s included

• 4 sizes: 2-5 mm, 5-10 mm, 10-15 mm, 15-20 mm
• Round shank for stable seating in standard drill chucks
• Material: High Speed Steel HSS 4241 for durability and dependable cuts
• 90° chamfer point for crisp countersinking and smooth edge finish

Real-world use cases

Whether you’re deburring a metal panel, preparing a wooden trim edge, or shaping a plastic opening, these bits help you achieve neat, consistent chamfers. The 90-degree tip concentrates cutting forces at the edge, producing clean edges that are ready for assembly or finishing without excessive post-processing.

• Metal, wood, and plastic applications with relatively soft hardness
• Compact, predictable cutting behavior ideal for hobby and light professional work
• Set features sizes that cover common hole diameters and edge preparation needs

Tips for best results

For best results, mount the bits in a bench drill rather than a handheld drill. Handheld use can introduce wobble that affects chamfer quality. Clamp workpieces securely and feed steadily to maintain edge precision.

With the OCGIG 4pc set, you gain a versatile, reliable toolkit for finishing touches on metal, wood, and plastic projects. While results depend on material and setup, users often experience crisper holes, smoother edges, and easier fastening when used in a controlled drilling setup.
