6-Piece 3-in-1 Titanium Coated Serrated HSS Drill Bit Set (3–8mm)

Take your drilling and grooving projects to the next level with this versatile 6-piece titanium-coated High-Speed Steel (HSS) serrated drill bit set. Engineered for woodworking, metalworking, and plastic cutting, these 3-in-1 bits let you drill, groove, and saw — all with a single tool. The set covers the six most commonly needed sizes: 3mm, 4mm, 5mm, 6mm, 6.5mm, and 8mm.

Made in Mainland China.

3-in-1 Functionality

  • Function 1 – Drill: Standard twist drilling through wood, aluminum, plastic, and softer metals.
  • Function 2 – Sawtooth Grooving: The serrated mid-section cuts precise grooves into your workpiece.
  • Function 3 – Saw Blade Action: Use the serrated edge to saw through thin wood boards and panels.

Key Features

  • Six Sizes Included: 3mm (0.12"), 4mm (0.16"), 5mm (0.20"), 6mm (0.24"), 6.5mm (0.26"), 8mm (0.31") — covers the most common drilling scenarios.
  • Titanium-Coated HSS 4241 Steel: The titanium plating significantly increases surface hardness and wear resistance for extended tool life.
  • Fully Ground Spiral Flutes: Engineered spiral grooves rapidly dissipate heat, enabling faster and cooler drilling performance.
  • 135° Split Point Tip: The precision split point prevents bit walking and starts drilling on contact — no center punch required.
  • Serrated Center Section: After drilling through, the serrations allow the bit to continue cutting horizontally for grooving work.
  • High Drilling Efficiency: Sharp cutting edges deliver maximum efficiency on each pass.
  • Universal Straight Shank: Compatible with virtually all standard electric drills and drill chucks.
  • Wide Material Compatibility: Suitable for stainless steel, cast iron, steel, wood, aluminum alloy, plastic boards, and other soft metals.

Frequently Asked Questions

Q: What materials can these serrated HSS drill bits cut through?

A: These titanium-coated HSS serrated drill bits are suitable for a wide range of materials including wood, thin wooden boards, aluminum alloy, plastic boards, stainless steel, cast iron, regular steel, and other softer metals. They are ideal for both drilling and grooving applications across woodworking and metalworking projects.

Q: Do I need a center punch before using these drill bits?

A: No — the 135° split point tip is specifically designed to grip the surface on contact and prevent bit walking, so no center punch is required. This makes setup faster and more convenient for everyday use.

Q: Are these bits compatible with standard electric drills?

A: Yes. These bits feature a standard straight shank design that is compatible with most electric drills and drill chucks available on the market, making them easy to install and swap out during projects.

Q: What is the advantage of the serrated (sawtooth) section on these drill bits?

A: The serrated mid-section gives these bits their 3-in-1 capability. After drilling through a material, the serrations allow the bit to cut horizontally for grooving. They can also function like a miniature saw blade on thin wood panels — combining three tools into one for greater efficiency and versatility.
