Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Precision Drilling: Designed for high-precision hole cutting in wood, metal, and other hard materials, featuring a serrated grooving structure that enhances cutting efficiency and reduces friction.
  • Versatile Spiral Design: The spiral saw drill bits enable smooth, continuous cutting action, minimizing material deformation and ensuring clean edges. The titanium coating on high-speed steel (HSS) provides superior heat resistance and durability for prolonged use.

Key features

  • 1. Material Technology

    • With a titanium-coated high-speed steel (HSS) body, these drill bits deliver exceptional heat resistance and corrosion protection. The titanium coating extends lifespan by ~20% compared to uncoated HSS bits*, ensuring durability in demanding woodworking tasks.

  • 2. Performance Parameters

    • Equipped with 6 precision diameters (3mm–8mm, 6.5mm), these bits accommodate a wide range of material thicknesses. The 100mm working length variant enables deep drilling, outperforming shorter bits in heavy-duty applications*.

  • 3. Scenario Solutions

    • Designed for both professional and DIY woodworking, the spiral flutes and serrated grooving ensure smooth, precise cutting in wood, metal, and plastic. Ideal for detailed cabinetry and large-scale construction projects*.

  • 4. Interactive Design

    • The spiral flutes efficiently remove debris during drilling, reducing clogging by ~30% compared to straight-fluted bits*. The round shank ensures secure grip in power tools, enhancing control and accuracy.

  • 5. Certification Standards

    • Manufactured with high-speed steel (HSS), a material renowned for industrial-grade durability, these bits meet safety and quality benchmarks for professional use. Compliance with international metalworking standards ensures reliability*.

Product details

3-10mm Serrated Side Cutting Twist Bit TiN Coated, Drill Saw Bit for Wood Plastic Metal Hole Drilling Slotting Trimming Grooving

The Titanium Coated HSS Serrated Grooving Carpenter Side Milling Spiral Saw Drill Bits Set combines precision engineering with versatile performance. Designed for woodworking and metalworking, these spiral drill bits feature high-speed steel (HSS) cores with titanium coating for enhanced durability and heat resistance. Their serrated grooving and spiral flutes ensure efficient chip removal, while varying diameters (3mm–8mm) and working lengths (3mm–100mm) cater to diverse drilling needs.

Customization guide

Adjustable diameter and length options allow customization to meet specific project needs. For example:

  • Diameter Selection: Choose smaller sizes (3mm–5mm) for delicate woodwork or larger diameters (6mm–8mm) for thicker materials.
  • Length Adaptation: Opt for shorter lengths (3mm–13mm) for shallow holes or the 100mm bit for deep drilling in sturdy materials.

Supplier's note

  1. Technical Breakthroughs:

    • Titanium Coating: Reduces friction by 30% compared to uncoated HSS, extending tool life.
    • Serrated Grooving: Achieves 20% faster chip ejection than smooth-edged bits.
    • Spiral Flutes: Enables 15% deeper penetration in dense materials like hardwood.

  2. Optimal Version Selection:

    • Base Model: Ideal for hobbyists or light-duty tasks (e.g., furniture assembly). Its 3–6mm diameters handle thin wood and plastics efficiently.
    • Advanced Model: Targets professionals needing mid-range versatility (e.g., cabinetry). The 4–8mm range and 50mm length suit thicker materials.
    • Pro Model: Designed for heavy-duty industrial use (e.g., structural metalwork). The 100mm length and diamond-like coating triple heat resistance, enabling safe drilling in high-temperature environments.

Example Use Case: The Pro version’s 100mm length and enhanced coating allow safe, deep drilling in stainless steel, while its serrated edges ensure minimal splintering in oak flooring.
