Professional 5-piece metal drill set with 4-10mm sizes, HSS 4241 steel, titanium nitride coating, 1/4" hex shank, and split point technology for precise drilling in stainless and cold-rolled steel.
Professional-grade metal drill bit set featuring 5 high-speed steel (HSS 4241) drill bits with titanium nitride coating and hexagonal 1/4" shank. This versatile set includes drill sizes ranging from 4mm to 10mm, making it ideal for drilling into stainless steel, acid-resistant steel, and cold-rolled steel materials. Each bit features a 135-degree drill point angle with split point technology, allowing for drilling without prior scoring and ensuring rapid heat dissipation during high-speed drilling operations.
The YATO YT-44700 drill set is engineered for professional applications requiring precision and durability. The titanium nitride coating provides superior hardness and wear resistance, extending tool life and maintaining sharp cutting edges through extended use. The split point design enables quick entry into the workpiece, reducing walking and improving accuracy. With overall lengths ranging from 100mm to 133mm and working part lengths from 43mm to 87mm, these drills accommodate various drilling depths and applications.
Designed to meet DIN 338 standards, this drill bit set is perfect for automotive work, metalworking, manufacturing, and general construction applications. The hexagonal shank ensures secure grip in compatible power tools and manual holders, preventing slippage during operation. Whether you're a professional tradesperson or serious DIY enthusiast, this durable metal drill set delivers consistent performance and reliability for demanding drilling tasks.
