Titanium HSS Countersink Chamfer Drill Set

🔧 Ragged Edges, Clogged Bits & Chipped Holes Slowing You Down?

Cheap countersink bits chatter, clog with chips, and leave rough, uneven chamfers that require hours of cleanup. When you're working with steel, hardwood, or acrylic, a poor-quality bit doesn't just slow you down — it ruins the workpiece. Precision starts with the right tool.

💡 Why Most Countersink Bits Fail Under Real Conditions

Uncoated HSS bits dull fast, especially on metal. Straight-fluted designs pack chips into the cut, causing heat buildup and rough finishes. And bits without a precise 90° angle produce inconsistent chamfers that don't seat screws flush. This set is engineered to eliminate all three problems.

⚡ 4 Sizes. Titanium Coated. Built to Last.

• 🌀 Spiral Flute Internal Chip Evacuation — The helical flute design pulls chips up and out of the cut continuously, preventing clogging and heat buildup. Cuts faster, cleaner, and quieter than straight-fluted alternatives — with no manual chip clearing needed.
• 🔵 Precise 90° Countersink Angle — Every bit is ground to an exact 90° point for sharp, accurate chamfering. Screws seat perfectly flush every time — no rocking, no proud heads, no secondary finishing required.
• 🛡️ Titanium-Coated HSS4241 Steel — The titanium nitride coating dramatically extends cutting life compared to bare HSS. Rust-proof, wear-resistant, and maintains a sharp edge through hundreds of cuts in wood, plastic, and soft metals.
• 📏 4-Size Set for Every Application — Chamfer ranges of 2–5mm, 5–10mm, 10–15mm, and 15–20mm cover the full spectrum of countersinking needs. Round shanks (6mm, 8mm, 10mm, 12mm) fit virtually all drill chucks and toolholding systems.
• 🏗️ Multi-Material Compatibility — Cuts cleanly through plywood, hardwood, acrylic, PVC, plastic, and metal (hardness <25 HRC). One set handles your entire workshop.
