✓Premium Material:This spiral drill bit set is made of high‑speed steel (HSS) with a nitriding treatment that significantly boosts wear resistance and durability. The fully ground spiral flute design quickly removes chips, reduces friction and heat, delivering faster drilling performance. A professional‑grade cutting drill bit set for all your woodworking needs.
✓6 Essential Sizes:Includes the 6 most commonly used sizes: 3mm, 4mm, 5mm, 6mm, 6.5mm, and 8mm – round shank for universal compatibility. Whether you're working on woodworking projects or drilling into harder wood materials, this drill bit set covers all your needs. Comes with a portable plastic bag for easy storage.
✓135° Split Point for Precision:The 135° split point with a straight shank prevents walking and allows for precise drilling – no center punch needed. The sharp cutting edge makes drilling faster and more effective. This spiral drill bit set is a great addition to your tool collection, combining drilling and sawing in one versatile bit.
✓Nitriding Treatment:The nitriding treatment chemically hardens the surface for superior wear resistance – it's a surface modification that never peels off. Unlike titanium coated drill bits that can wear off over time, this HSS drill bit set maintains its hardness and cutting performance for the long haul.
✓Efficient Serrated & Side Cutting Design:The sharp serrated design lets you drill horizontally after the initial hole is made. Featuring a side cutting drill bit design with a round shank, these bits fit securely into electric drills and drill presses without slipping. Safer, easier, and more reliable – a serrated drill bit set you can trust.
✓Wide Application:This round shank serrated drill bit set is ideal for DIY projects, home maintenance, and repairs. Perfect for grooving, boring, or cutting 1‑2mm thin materials like wood, solid wood, plywood, plastic board, thin aluminum, thin steel sheet, and thin aluminum alloy.
