High-Performance Materials:Made of 6542 HSS taps and M35 cobalt drill bits, ensuring high hardness, wear resistance, and long service life
Efficient Spiral Point Design:The spiral point tap facilitates smooth downward chip evacuation, ensuring burr-free threads and smooth drilling results, making it ideal for through-hole threading in both metals and plastics
Double Rust Prevention: Roasted yellow drill bits remove metal surface oxidation for better corrosion resistance; Ti-coated taps enhance rust/heat resistance & reduce cutting friction, durable in damp environments or high-temperature processing
Stable and Reliable: All tools undergo heat treatment for higher structural strength, withstanding frequent use – reliable for both hobbyists' DIY projects and technicians' professional processing
Broad Applications:Designed for metalworking, automotive, electronics & DIY projects – complete 2.5mm drilling + M3×0.5 threading in one set.Use with tapping oil/lubricant to improve thread quality & tool durability
