⚙️ KEY FEATURES
► Premium Titanium-Coated HSS
Crafted from high-speed steel (HSS) with a titanium-plated surface — high hardness, anti-oxidation, rust-resistant, and built for repeated professional use. Hardness: HRC55–58.
► Drill Faster & Stay Sharper
Titanium coating keeps edges sharper for longer, enabling higher drilling speeds than uncoated or oxide-coated bits — less downtime, more output.
► Less Debris, Cleaner Holes
Double U-shape flute design efficiently clears chips and reduces splashing debris — for cleaner, more precise results every time.
► Versatile Compatibility
Fits hand drills, lithium electric drills, and electric grinders. Ideal for hardwood, plastic, PVC, aluminum plate, thin iron sheet, circuit boards, jade, walnut, and more.
► Complete Size Range
Choose from 50, 60, 70, or 99-piece sets to match your project scale. The 99-piece set covers 1.5mm–10mm across 14 sizes — everything you need in one organized metal case.
